Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund's investment objective is long-term growth of capital.
Expense [Heading]	rr_ExpenseHeading	<b>Fees and Expenses of the Fund </b>
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Investors may pay commissions and/or other forms of compensation to an intermediary, such as a broker, for transactions in Class R6 shares, which are not reflected in the table or the Example below.

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<b>Portfolio Turnover.</b>
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 46% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	46.00%
Expense Example [Heading]	rr_ExpenseExampleHeading	<b>Example.</b>
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. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	<b>Principal Investment Strategies of the Fund </b>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities and depositary receipts of foreign issuers of all capitalization sizes, including small and mid-capitalization issuers. The principal types of equity securities in which the Fund invests are common and preferred stock. The Fund’s common stock investments also include China-A shares (shares of companies based in mainland China that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange). Under normal circumstances, the Fund will provide exposure to investments that are economically tied to at least three different countries outside of the U.S. The Fund may also invest up to 30% of its net assets in emerging markets countries, i.e., those that are in the early stages of their industrial cycles. The Fund invests primarily in securities of issuers that are considered by the Fund’s portfolio managers to have potential for earnings or revenue growth. The Fund does not intend to hedge the currency exposure created by its investments in foreign securities but has the ability to do so if deemed appropriate by the Fund’s portfolio managers. To achieve the Fund’s objective, the portfolio management team applies a rigorous bottom-up fundamental investment approach to analyze the quality and value of individual companies to determine whether or not to invest in them. The portfolio management team looks for companies: That meet strict quality business criteria That meet standards of management quality That are believed to be attractively priced in relation to their intrinsic value As part of a comprehensive assessment of a company’s intrinsic value, the team uses a variety of valuation methods and will typically review a company’s financial information, competitive position and its future prospects. The team may also meet with the company’s management and take into account general industry and economic trends. The team will then compare the intrinsic value that it has placed on the company against its current market price, and will consider investing where the market price is sufficiently lower than the value that the team has determined. The portfolio management team will typically sell a security under the following conditions: (1) where the price of the security increases to a level that the team considers to be at or near its intrinsic value, (2) where there are more attractive opportunities, or (3) where the original investment thesis for a company is no longer valid.
Risk [Heading]	rr_RiskHeading	<b>Principal Risks of Investing in the Fund </b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Depositary Receipts Risk. Investing in depositary receipts involves the same risks as direct investments in foreign securities. In addition, the underlying issuers of certain depositary receipts are under no obligation to distribute shareholder communications or pass through any voting rights with respect to the deposited securities to the holders of such receipts. The Fund may therefore receive less timely information or have less control than if it invested directly in the foreign issuer. Emerging Markets Securities Risk. Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably. The Fund's investments in China A-shares are subject to trading restrictions, quota limitations and clearing and settlement risks. In addition, investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, and lack of timely information. Foreign Securities Risk. The Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls. Unless the Fund has hedged its foreign securities risk, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. Geographic Focus Risk. The Fund may from time to time invest a substantial amount of its assets 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. Growth Investing Risk. Growth stocks tend to be more expensive relative to the issuing company’s earnings or assets compared with other types of stock. As a result, they tend to be more sensitive to changes in, or investors’ expectations of, the issuing company’s earnings and can be more volatile. Investing in the European Union Risk. Investments in certain countries in the European Union are susceptible to high economic risks associated with high levels of debt, such as investments in sovereign debt of Greece, Italy and Spain. Efforts of the member states to further unify their economic and monetary policies may increase the potential for the downward movement of one member state’s market to cause a similar effect on other member states’ markets. Separately, the European Union faces issues involving its membership, structure, procedures and policies. The exit of one or more member states from the European Union, such as the United Kingdom (UK) which has announced its intention to exit, would place its currency and banking system in jeopardy. The exit by the UK or other member states will likely result in increased volatility, illiquidity and potentially lower economic growth in the affected markets, which will adversely affect the Fund’s investments. 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. 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. 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. Individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. 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. Preferred Securities Risk. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities also may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non-payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Sector Focus Risk. The Fund may from time to time invest a significant amount of its assets (i.e. over 25%) in one market sector or group of related industries. In this event, the Fund’s performance will depend to a greater extent on the overall condition of the sector or group of industries and there is increased risk that the Fund will lose significant value if conditions adversely affect that sector or group of industries. Small- and Mid-Capitalization Companies Risks. 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, and their returns may vary, sometimes significantly, from the overall securities market.

[1] Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding Acquired Fund Fees and Expenses and certain items discussed in the SAI) of each of Class R5 and Class R6 shares to 0.87% of the Fund's average daily net assets (the “expense limits”). Invesco has also contractually agreed to waive a portion of the Fund's management fee in an amount equal to the net management fee that Invesco earns on the Fund's investments in certain affiliated funds, which will have the effect of reducing the Acquired Fund Fees and Expenses. Unless Invesco continues the fee waiver agreements, they will terminate on February 29, 2020 and June 30, 2020, respectively. During their terms, the fee waiver agreements cannot be terminated or amended to increase the expense limits or reduce the advisory fee waiver without approval of the Board of Trustees.
