Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $25,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 38 in the Fund’s Prospectus and under “Buying and Selling Shares” on page 64 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – “Intermediary Sales Charge Discounts and Waivers” to the Fund’s prospectus.

Please note that the tables and examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or Advisor Class shares.

Portfolio Turnover [Text Block] rr_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 29.07% of the average value of its portfolio.

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 the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. 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

Under normal market conditions, the Fund invests at least 80% of its net assets in foreign securities. These securities are predominantly equity securities of companies located outside the U.S., including developing markets. The equity securities in which the Fund invests are predominantly common stock, and may include small and mid capitalization companies. Although the investment manager will search for investments across a large number of regions, countries and sectors, from time to time, based on economic conditions, the Fund may have significant positions in particular regions, countries or sectors.

The investment manager may consider selling an equity security when it believes the security has become overvalued due to either its price appreciation or changes in the company's fundamentals, or when the investment manager believes another security is a more attractive investment opportunity.

The Fund may, from time to time, engage in currency-related derivatives, such as currency and cross-currency forwards and currency futures contracts, to seek to hedge (protect) against currency risks.

When choosing equity investments for the Fund, the investment manager applies a “bottom-up,” value-oriented, long-term approach, focusing on the market price of a company’s securities relative to the investment manager’s evaluation of the company’s long-term earnings, asset value and cash flow potential. The investment manager also considers a company’s price/earnings ratio, price/cash flow ratio, profit margins and liquidation value.

The Fund may also use a variety of equity-related derivatives, which may include equity futures and equity index futures, for various purposes including enhancing Fund returns, increasing liquidity and gaining exposure to particular markets in more efficient or less expensive ways.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not

insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

The current global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, volatility in consumer demand for certain products, defaults and credit ratings downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic is unpredictable and may adversely affect the Fund’s performance.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Foreign Securities (non-U.S.) Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

Currency Management Strategies   Currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the investment manager

expects. In addition, currency management strategies, to the extent that they reduce the Fund’s exposure to currency risks, also reduce the Fund’s ability to benefit from favorable changes in currency exchange rates. Using currency management strategies for purposes other than hedging further increases the Fund’s exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.

Regional Focus Because the Fund may invest at least a significant portion of its assets in companies in a specific region, including Europe, the Fund is subject to greater risks of adverse developments in that region and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the region, even in countries in which the Fund is not invested, may adversely affect the value of investments held by the Fund. Current uncertainty concerning the economic consequences of the January 31, 2020 departure of the United Kingdom from the European Union (EU) and Russia’s military invasion of Ukraine in February 2022 may increase market volatility.

Developing Market Countries The Fund’s investments in securities of issuers in developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Value Style Investing A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur or do not have the anticipated effect.

Liquidity From time to time, the trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

Management The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment

techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Cybersecurity Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager and their service providers are subject to the risk of cyber incidents occurring from time to time.

Focus To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

Small and Mid Capitalization Companies Securities issued by small and mid capitalization companies may be more volatile in price than those of larger companies and may involve additional risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, small and mid capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.

Derivative Instruments The performance of derivative instruments (including currency derivatives) depends largely on the performance of an underlying instrument, such as a currency, security, interest rate or index, and such derivatives often have risks similar to the underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund’s portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that significantly exceeds the Fund’s initial investment. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. Their successful use will usually depend on the investment manager’s ability to accurately forecast movements in the market relating to the underlying instrument. Should a market or markets, or prices of particular classes of investments move in an unexpected manner, especially in unusual or extreme market conditions, the Fund may not achieve the anticipated benefits of the transaction, and it may realize losses, which could be significant. If the investment manager is not successful in using such derivative instruments, the Fund’s performance may be worse than if the investment manager did not use such derivatives at all. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate or other risk being hedged. Derivatives also may present the risk that the other party to the transaction will fail to perform. There is also the risk, especially under extreme market conditions, that a derivative, which usually would operate as a hedge, provides no hedging benefits at all.

The figures in the average annual total returns table above reflect the Class A shares maximum front-end sales charge of 5.50%. Prior to September 10, 2018, Class A shares were subject to a maximum front-end sales charge of 5.75%. If the

prior maximum front-end sales charge of 5.75% was reflected, performance for Class A shares in the average annual total returns table would be lower.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

There is a 1% contingent deferred sales charge that applies to investments of $1 Million or more (see "Investment of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.
[2] The transfer agent has contractually agreed to cap transfer agency fees for Class R6 shares of the Fund so that the transfer agency fees for that class do not exceed 0.03% until December 31, 2023. During the term, this fee waiver and expense reimbursement agreement may not be terminated or amended without approval of the board of trustees except to add series and classes, to reflect the extension of termination dates or to lower the cap on Fund’s fees and expenses (which would result in lower fees for shareholders).
[3] The investment manager has contractually agreed to waive or assume certain expenses so that total annual Fund operating expenses (excluding Rule 12b-1 fees, acquired fund fees and expenses and certain nonroutine expenses) for each class of the Fund do not exceed 0.85% until December 31, 2023. During the term, this fee waiver and expense reimbursement agreement may not be terminated or amended without approval of the board of trustees except to add series and classes, to reflect the extension of termination dates or to lower the cap on the Fund’s fees and expenses (which would result in lower fees for shareholders).
