| Objective [Heading] | rr_ObjectiveHeading | Investment Objective(s) | ||||||||||||||||||||||||||||

| Expense [Heading] | rr_ExpenseHeading | Fees and Expenses | ||||||||||||||||||||||||||||
| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below. |
||||||||||||||||||||||||||||
| Shareholder Fees Caption [Text] | rr_ShareholderFeesCaption | Shareholder fees (fees paid directly from your investment) | ||||||||||||||||||||||||||||

| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||||||||||||||||||||||
| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | Portfolio Turnover 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 the fund’s 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 15.4% of the average value of its portfolio. |

| Expense Example [Heading] | rr_ExpenseExampleHeading | Example | ||||||||||||||||||||||||||||
| Expense Example Narrative [Text Block] | rr_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, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in the emerging markets of Europe, including Eastern Europe and the former Soviet Union. For purposes of determining whether the fund invests at least 80% of its net assets in emerging European countries, the fund relies on the country assigned to a security by MSCI Inc., a third party provider of benchmark indexes and data services, or another unaffiliated data provider. The fund also relies on MSCI Inc. or another unaffiliated data provider to determine which countries are considered emerging markets. The fund considers frontier markets to be a subset of emerging markets, and any investments in frontier markets will be counted toward the fund’s 80% investment policy. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy. The fund expects to primarily invest in common stocks of companies located (or with primary operations) in emerging markets of Europe. Historically, the fund has typically invested significantly in Russia; however, the fund is no longer making new investments in Russia although it continues to hold certain Russian securities that have been valued effectively at zero. Going forward, the countries in which the fund expects to normally invest include, but are not limited to, the following: · Primary Emphasis: Czech Republic, Greece, Hungary, Poland, Romania, and Türkiye. · Others: Bulgaria, Croatia, Estonia, Georgia, Kazakhstan, Latvia, Lithuania, Slovakia, Slovenia, and Ukraine. The emerging European investable universe, due to its limited geographic scope and less developed markets, tends to rely heavily on the success of certain industries and sectors. As a result, the fund may invest up to 35% of its net assets in any industry that accounts for more than 20% of the emerging European market as a whole, as measured by an index determined by T. Rowe Price to be an appropriate measure of the emerging European market (currently the MSCI Emerging Markets Europe Index). The fund is “nondiversified,” meaning it may invest a greater portion of its assets in a single issuer and own more of the issuer’s voting securities than is permissible for a “diversified” fund. The fund may purchase the stocks of companies of any size. While the adviser invests with an awareness of the adviser’s outlook for certain industries, sectors, and individual countries within the region, the adviser’s decision-making process focuses on bottom-up stock selection. Country allocation is driven largely by stock selection, though the adviser may limit investments in markets or industries that appear to have poor overall prospects. The adviser does not emphasize either a growth or value bias in selecting investments for the fund, and generally seeks stocks that the adviser believes have the most favorable combination of company fundamentals, earnings potential, and relative valuation. In selecting investments, the adviser generally favors companies with one or more of the following characteristics: · leading or improving market position; · attractive business niche; · attractive or improving franchise or industry position; · seasoned management; · stable or improving earnings and/or cash flow; and · sound or improving balance sheet. At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the financial sector. |

| T. Rowe Price Emerging Europe Fund | Investing in Emerging Europe | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Emerging Europe: The European financial markets have experienced increased volatility due to concerns about economic downturns, political unrest, war, military conflict, economic sanctions, rising government debt levels, energy crises, and public pandemics, and these events may continue to significantly affect all of Europe. The economies and markets of European countries are often connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. European economies could be significantly affected by, among other things, rising unemployment, the imposition or unexpected elimination of fiscal and monetary controls by member countries of the European Economic and Monetary Union, uncertainty surrounding the euro, the success of governmental actions to reduce budget deficits, and the ongoing conflict between Russia and Ukraine. Emerging European countries are more susceptible to political turmoil, recession, varying market reforms, and adverse currency fluctuations as their economies continue to develop. The securities markets in some emerging European countries are substantially smaller and less established, with less government supervision and regulation of stock exchanges, and may be less liquid and more volatile than securities markets in the U.S. or developed European countries. In addition, there tends to be less information available about issuers in emerging Europe and their markets may experience limited trading volumes and reduced liquidity. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Emerging markets | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Emerging markets: Investments in emerging market countries are subject to greater risk and overall volatility than investments in the U.S. and other developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, less developed legal and regulatory regimes, and political systems that are less stable, than those of developed countries. In addition to the risks associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Geographic concentration | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Geographic concentration: Because the fund focuses its investments on a particular geographic area, the fund’s performance is closely tied to the social, political, and economic conditions of that area. Political developments and changes in regulatory, tax, or economic policy could significantly affect the markets in which the fund invests. As a result, the fund is likely to be more volatile than more geographically diverse international funds. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Industry concentration | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Industry concentration: Because the fund may invest significantly in any industry that accounts for more than 20% of the emerging European market, the fund is more susceptible to adverse developments affecting such industries and may perform poorly during a downturn in one of the industries that are heavily represented in emerging Europe. For example, the fund may invest significantly in banks and other financial services companies. Banks can be adversely affected by, among other things, regulatory changes, interest rate movements, the availability of capital and cost to borrow, and the rate of debt defaults. The oversight of banks in emerging markets may be ineffective and underdeveloped relative to more mature markets. In particular for emerging markets, the impact of future regulation on any individual bank, or on the financial services sector as a whole, can be very difficult to predict. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Frontier markets | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Frontier markets: Frontier markets generally have smaller economies and less mature capital markets than emerging markets. As a result, the risks associated with investing in emerging market countries are magnified in frontier market countries. Frontier markets are more susceptible to abrupt changes in currency values, have less mature markets and settlement practices, and can have lower trading volumes that could lead to greater price volatility and illiquidity. Investor protections in frontier market countries may be limited and settlement procedures and custody services may prove inadequate in certain markets. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | International investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | International investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Investing in Türkiye | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Türkiye: Investments in Turkish issuers are subject to legal, regulatory, political, currency, and economic risks specific to Türkiye. The Turkish economy is prone to, among other things, risks of sharp currency devaluations, legal and regulatory changes, natural disasters, social unrest, terrorism, and geopolitical tensions. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Investing in Russia | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investing in Russia: On February 24, 2022, Russia launched a large-scale military invasion of Ukraine, which has resulted in sanctions and market disruptions, including significant declines in Russia’s stock markets and the value of the ruble against the U.S. dollar. In response to Russia’s invasion of Ukraine, the U.S. and other countries instituted sanctions against Russia that, among other things, restrict certain securities trades and private transactions in certain sectors and prohibit doing business with certain Russian individuals and Russian companies. In addition, for investors in the U.S. and many other countries, Russia has banned purchases and sales of Russian securities traded on its local stock exchange. Accordingly, the Russian stock market has become largely uninvestable to foreign investors, such as the fund, and it is uncertain when these restrictions on trading or transferring Russian securities may be reduced or eliminated. As a result of these market events, the locally traded Russian securities that are held in the fund’s portfolio generally cannot be sold or transferred and have been valued effectively at zero. Prior to reducing the value of Russian securities to zero, the fund had a significant amount of its assets invested in Russian securities. There is no assurance that the fund will be able to realize any value from these securities in the future. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Market conditions | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Liquidity | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Risk Nondiversified Status [Member] | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Nondiversification: As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified. |
||||||||||||||||||||||||||||
| T. Rowe Price Emerging Europe Fund | Stock investing | ||||||||||||||||||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry. |
||||||||||||||||||||||||||||

| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies. |

| Risk/Return: | rr_RiskReturnAbstract | |||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. |
