Which European powers fought against Napoleonic France?

During the Napoleonic Wars, Napoleonic France faced a series of shifting alliances formed by various European powers determined to challenge French hegemony. These coalitions were not static, as different nations joined or withdrew based on political and military circumstances.12

Key European powers that fought against France at various times included:

• Great Britain: A persistent opponent that provided significant financial subsidies to its allies to support military campaigns against Napoleon.13
• Russia: A major power that frequently engaged in the coalitions, though its commitment fluctuated throughout the period.13
• Austria: A central participant in the coalitions, often motivated by the preservation of Habsburg influence and opposition to French expansion in Italy and Germany.3
• Sweden: An active member of the anti-French alliances, particularly during the formation of the Third Coalition.3

While these nations formed the backbone of the resistance, the alliances were complex, and some smaller states, such as Bavaria, Baden, and Württemberg, occasionally aligned with France to pursue their own territorial interests against rivals like Austria.3
