Federated Hermes International Leaders Fund Investment Risks - Federated Hermes International Leaders Fund	Nov. 30, 2025
Stock Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Stock Market Risk. The value of equity securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s Share price may decline suddenly or over a sustained period of time. Information publicly available about a company, whether from the company’s financial statements or other disclosures or from third parties, or information available to some but not all market participants, can affect the price of a company’s shares in the market. Among other factors, equity securities may decline in value because of an increase in interest rates or changes in the stock market. Recent and potential future changes in industry and/or economic trends, as well as changes in monetary policy made by central banks and/or their governments, also can affect the level of interest rates and contribute to the development of or increase in volatility, illiquidity, shareholder redemptions and other adverse effects (such as a decline in a company’s stock price), which could negatively impact the Fund’s performance.
Risk of Foreign Investing [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Foreign Investing. The foreign markets in which the Fund invests may be subject to economic or political conditions which are less favorable than those of the United States and may lack financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies.
Risk of Investing in Depositary Receipts and Domestically Traded Securities of Foreign Issuers [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Investing in Depositary Receipts and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts and other domestically traded securities of foreign companies, whether in the United States or in foreign local markets, the Fund’s Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
Currency Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Currency Risk. Because the exchange rates for currencies fluctuate daily, prices of the foreign securities in which the Fund invests are more volatile than prices of securities traded exclusively in the United States.
European Union and Eurozone Related Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	European Union and Eurozone Related Risk. A number of countries in the European Union (EU), including certain countries within the EU that have adopted the euro (Eurozone), have experienced, and may continue to experience, severe economic and financial difficulties. Additional countries within the EU may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund’s investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.
Investment Style Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Investment Style Risk. The Fund may employ a combination of styles that impact its risk characteristics, such as growth and value investing. Due to the Fund’s style of investing, the Fund’s Share price may lag that of other funds using a different investment style.
Risk of Investing in Emerging Market Countries [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Securities markets within emerging market countries may experience low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities. Political and economic structures in emerging market countries generally lack the social, political and economic stability of developed countries, which may affect the value of the Fund’s investments in these countries. There may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing, and financial reporting standards comparable to those to which U.S. companies are subject.
Custodial Services and Related Investment Costs [Member]
Prospectus [Line Items]
Risk [Text Block]	Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. In addition, security settlement and clearance procedures in some emerging market countries may not fully protect the Fund against loss of its assets.
Exchange Traded Funds Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Exchange-Traded Funds Risk. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange traded). In addition, ETFs may be subject to the following risks that do not apply to conventional funds: (i) the market price of an ETF’s shares may trade above or below their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate.
Risk of Investing in Derivative Contracts and Hybrid Instruments [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts and instruments include valuation and tax issues, increased potential for losses and/or costs to the Fund, and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts and hybrid instruments may also involve other risks described in this Prospectus such as stock market, credit, currency, liquidity and leverage risks.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk. Trading opportunities are more limited for equity securities that are not widely held. This may make it more difficult to sell or buy a security at a favorable price or time. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to.
Leverage Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Leverage Risk. Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain. Investments can have these same results if their returns are based on a multiple of a specified index, security or other benchmark.
Counterparty Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Counterparty Risk. Counterparty risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
Risk Related to the Economy [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions including geopolitical and other events (e.g., wars, sanctions and terrorism), legislative changes, industry or economic trends and developments, natural disasters or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on the economies of many nations, including the U.S., and financial markets generally and cause the Fund to experience volatility, illiquidity, loss of value, shareholder redemptions, and/or other potentially adverse effects.
Technology Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
