List of French client states

French client states were territories directly influenced or controlled by France, often established during periods of political expansion, such as the Napoleonic era. These states served as strategic allies or buffer zones, with governments typically aligned with French interests and policies. Spanning Europe, Africa, Southeast Asia, and the Americas, these client states played a significant role in extending France's geopolitical reach.
