Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.
The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.
Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 34% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The Fund mainly invests in the common stock of growth companies that are domiciled or have their primary operations outside of the United States. The Fund may invest 100% of its assets in securities of foreign companies. The Fund may invest in emerging markets (i.e., those that are generally in the early stages of their industrial cycles) as well as in developed markets throughout the world. From time to time the Fund may place greater emphasis on investing in one or more particular regions such as Europe or Asia. Under normal market conditions the Fund will:
■ 
invest at least 65% of its total assets in common and preferred stocks of issuers in at least three different countries outside of the United States, and
■ 
emphasize investments in common stocks of issuers that are considered by the Fund’s portfolio managers to have potential for earnings or revenue growth.
The Fund does not limit its investments to issuers within a specific market capitalization range and at times may invest a substantial portion of its assets in one or more particular capitalization ranges. The Fund can also buy preferred stocks, securities convertible into common stock and other securities having equity features.
In selecting investments for the Fund’s portfolio, the portfolio managers evaluate investment opportunities on a company-by-company basis. The portfolio managers look primarily for foreign companies with high growth potential using a “bottom up” investment approach, that is, by looking at the investment performance of individual stocks before considering the impact of general or industry-specific economic trends. This approach includes fundamental analysis of a company’s financial statements and management structure and consideration of the company’s operations, product development, and industry position.
The portfolio managers currently focus on the following factors, which may vary in particular cases and may change over time:
■ 
companies that enjoy a strong competitive position and high demand for their products or services;
■ 
companies with accelerating earnings growth and cash flow; and
■ 
diversity among companies, industries and countries to help reduce the risks of foreign investing, such as currency fluctuations and stock market volatility.
The portfolio managers also consider the effect of worldwide trends on the growth of particular business sectors and look for companies that may benefit from those trends. The trends currently considered include: mass affluence, new technologies, restructuring and aging. The portfolio managers do not invest any fixed amount of the Fund’s assets according to these criteria and the trends that are considered may change over time. The
portfolio managers monitor individual issuers for changes in the factors above, which may trigger a decision to sell a security, but does not require a decision to do so.
Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading Performance Information
Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock
The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer International Growth Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad measure of market performance and an additional index with characteristics relevant to the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund. Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund were reorganized into Class A, Class C, Class R, Class Y and Class R6 shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.
Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Investing in Stocks Risk. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.
The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), Fund share values may fluctuate more in response to events affecting the market for those types of securities.

Risk [Text Block] oef_RiskTextBlock
Preferred Securities Risk. There are special risks associated with investing in preferred securities compared to those applicable generally to equity securities. Preferred securities may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Preferred securities also may be subordinated to bonds or other debt instruments in an issuer’s capital structure, subjecting them to a greater risk of non-payment than more senior securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it
may not have received any income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of possible seizure, expropriation, nationalization, political or social instability, changes in economic or taxation policies or other adverse political or economic developments (in which the Fund could lose its entire investments in a certain market) and the difficulty of enforcing obligations in other countries, including the possible adoption of foreign governmental restrictions such as exchange controls. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. To the extent the Fund invests in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns, unless the Fund has hedged its foreign currency exposure. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, may not always be successful. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. From time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company’s performance. Additionally, one or more of these companies could suffer damage to its reputation if the market identifies it as a company that invests or deals with countries that the U.S. government identifies as state sponsors of terrorism or is subject to sanctions.

Geographic Focus Risk. The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund’s investment performance.
Invesco International Growth Fund | Invesco International Growth Fund | European Investment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
European Investment Risk. The Economic and Monetary Union (the EMU) of the European Union (the EU) requires compliance by member countries with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have significant adverse effects on the economies of EU member countries and the EU and Europe as a whole. Responses to these and other financial problems by European governments, central banks, and others, including austerity measures and reforms, may not produce the desired results, may limit future growth and economic recovery, or may result in social unrest, or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets, and asset valuations around the world. A number of countries in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments. Separately, the EU faces issues involving its membership, structure, procedures and policies. The exit of one or more
member countries from the EU, such as the departure of the United Kingdom (the UK), referred to as Brexit, could place the departing member’s currency and banking system under severe stress or even in jeopardy. An exit by other member countries will likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which will adversely affect the Fund’s investments.

Risk [Text Block] oef_RiskTextBlock Asia Pacific Region Risk (including Japan). The level of development of the economies of countries in the Asia Pacific region varies greatly. Furthermore, since the economies of the countries in the region are largely intertwined, if an economic recession is experienced by any of these countries, it will likely adversely impact the economic performance of other countries in the region. Certain economies in the region may be adversely affected by increased competition, high inflation rates, undeveloped financial services sectors, currency fluctuations or restrictions, political and social instability and increased economic volatility.The Fund’s Japanese investments may be adversely affected by protectionist trade policies, slow economic activity worldwide, dependence on exports and international trade, increasing competition from Asia’s other low-cost emerging economies, political and social instability, regional and global conflicts and natural disasters, as well as by commodity markets fluctuations related to Japan’s limited natural resource supply. The Japanese economy also faces several other concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits.Investments in companies located or operating in Greater China (normally considered to be the geographical area that includes mainland China, Hong Kong, Macau and Taiwan) involve risks and considerations not typically associated with investments in the U.S. and other Western nations, such as greater government control over the economy; political, legal and regulatory uncertainty; nationalization, expropriation, or confiscation of property; lack of willingness or ability of the Chinese government to support the economies and markets of the Greater China region; lack of publicly available information and difficulty in obtaining information necessary for audits of, investigations into and/or litigation against Chinese companies, as well as in obtaining and/or enforcing judgments; limited legal remedies for shareholders; alteration or discontinuation of economic reforms; complex geopolitical tensions, military conflicts and the risk of war, either internal or with other countries; assertions of human rights violations by certain nations; public health emergencies resulting in market closures, travel restrictions, quarantines or other interventions; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of Greater China; and Greater China’s dependency on the economies of other Asian countries, many of which are developing countries. Events in any one country or region within Greater China may impact the other countries or regions or Greater China as a whole. Export growth continues to be a major driver of China’s rapid economic growth. As a result, a reduction in spending on Chinese products and services, the institution of additional tariffs, sanctions, capital controls, embargoes, trade wars, or other trade barriers (or the threat thereof), including as a result of trade tensions between China and the United States, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. In addition, actions by the U.S. government, such as delisting of certain Chinese companies from U.S. securities exchanges or otherwise restricting their operations in the U.S., may negatively impact the value of such securities held by the Fund. Further, from time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company’s performance. Additionally, the Public Company Accounting Oversight Board (PCAOB) has historically had difficulties in inspecting audit work papers and practices of PCAOB-registered accounting firms in China with respect to their audit work of U.S. reporting companies. These difficulties may impose significant additional risks concerning the reliability of the audits and of the information about the Chinese securities or the potential delisting of a U.S.-listed Chinese issuer due to an inability to inspect the issuer’s accounting firm.Investments in Chinese companies may be made through a special structure known as a variable interest entity (VIE) that is designed to provide foreign investors, such as the Fund, with exposure to Chinese companies that operate in certain sectors in which China restricts or prohibits foreign investments. Investments in VIEs may pose additional risks because the investment is made through an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company in order to provide investors with exposure to the operating company, and therefore does not represent equity ownership in the operating company. The value of the shell company is derived from its ability to consolidate the VIE into its financials pursuant to contractual arrangements that allow the shell company to exert a degree of control over, and obtain economic benefits arising from, the VIE without formal legal ownership. The contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor’s (such as the Fund’s) rights may be limited, including by actions of the Chinese government which could determine that the underlying contractual arrangements are invalid. While VIEs are a longstanding industry practice and are well known by Chinese officials and regulators, historically the structure has not been formally recognized under Chinese law. However, effective March 31, 2023, the China Securities Regulatory Commission (CSRC) released new rules and implementing guidelines that permit the use of VIE structures, provided they abide by Chinese laws and register with the CSRC. The rules, however, may cause Chinese companies to undergo greater scrutiny and may make the process to create VIEs more difficult and costly. Further, while the rules and implementing guidelines do not prohibit the use of VIE structures, this does not serve as a formal endorsement by the Chinese government. There is a risk that the Chinese government may cease to tolerate VIEs at any time, and any guidance or further rulemaking prohibiting or restricting these structures by the Chinese government, generally or with respect to specific industries, would likely cause impacted VIE-structured holding(s) to suffer significant, detrimental, and possibly permanent losses, and in turn, adversely affect the Fund’s, returns and net asset value. The future of the VIE structure generally and with respect to certain industries remains uncertain.Certain securities issued by companies located or operating in Greater China, such as China A-shares, are subject to trading restrictions and suspensions, quota limitations and sudden changes in those limitations, and operational, clearing and settlement risks. Additionally, developing countries, such as those in Greater China, may subject the Fund’s investments to a number of tax rules, and the application of many of those rules may be uncertain. Moreover, China has implemented a number of tax reforms in recent years, and may amend or revise its existing tax laws and/or procedures in the future, possibly with retroactive effect. Changes in applicable Chinese tax law could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies in China in which the Fund invests. Uncertainties in Chinese tax rules could result in unexpected tax liabilities for the Fund.

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Emerging markets usually are
subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

Risk [Text Block] oef_RiskTextBlock
Growth Investing Risk. The market values of growth securities may be more volatile than other types of investments. The returns on growth securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. If a growth company’s earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, the value of its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth securities typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price and the securities of growth companies may underperform the securities of value companies or the overall stock market. Growth stocks may also be more volatile than other securities because of investor speculation and the value of the Fund’s investments will vary and at times may be lower than that of other types of investments.

Risk [Text Block] oef_RiskTextBlock
Small- and Mid-Capitalization Companies Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all.

Convertible Securities Risk. The market values of convertible securities are affected by market interest rates, the risk of actual issuer default on interest or principal payments and the value of the underlying common stock into which the convertible security may be converted. Additionally, a convertible security is subject to the same types of market and issuer risks that apply to the underlying common stock. In addition,
certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of certain triggering events, and, as a result, are subject to an increased risk of loss. Convertible securities may be rated below investment grade and therefore considered to have more speculative characteristics and greater susceptibility to default or decline in market value than investment grade securities.
Invesco International Growth Fund | Invesco International Growth Fund | Valuation Risk [Member]

Risk [Text Block] oef_RiskTextBlock
Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

Management Risk. The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser's investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

[1] A contingent deferred sales charge may apply in some cases. See “Shareholder Account Information-Contingent Deferred Sales Charges (CDSCs).”
[2] Performance shown on or prior to the inception date is that of the predecessor fund's Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R5 shares' returns of the Fund will be different from Class A shares' returns of the predecessor fund as they have different expenses.
