During the [[French Revolution|Revolutionary]] and [[Napoleonic era]]s (1789–1815), France conquered most of [[western Europe]] and established several client states.

At first, during the [[French Revolutionary Wars]], these states were erected as "''Républiques soeurs''" ("[[sister republic]]s"). They were established in Italy (the [[Cisalpine Republic]] in [[Northern Italy]] and the [[Parthenopean Republic]] in [[Southern Italy]]), Greece ([[French rule in the Ionian Islands (1797–1799)|''Îles Ioniennes'']]), Switzerland (the [[Helvetic Republic]] and the [[Valais Republic|Rhodanic Republic]]), and Belgium and the Netherlands ([[Batavian Republic]]).

During the [[First French Empire]], while [[Napoleon|Napoleon I]] and the [[French Imperial Army (1804–1815)|French Army]] occupied much of [[Europe]], such states changed, and several new states were formed. The Italian republics were transformed into the [[Kingdom of Italy (Napoleonic)|Kingdom of Italy]] under Napoleon's direct rule in the north, and the [[Kingdom of Naples (Napoleonic)|Kingdom of Naples]] in the south, first under [[Joseph Bonaparte]] and later under [[Marshal of the Empire|Marshal]] [[Joachim Murat]]. A third state was created in the Italian Peninsula, the [[Kingdom of Etruria]]. The Batavian Republic was replaced by the [[Kingdom of Holland]], ruled by Napoleon's third brother, [[Louis Bonaparte]].

A total of 35 German states, all of them allies of France, seceded from the [[Holy Roman Empire]] to create the [[Confederation of the Rhine]], a client state created to provide a buffer between France and its two largest enemies to the east, [[Kingdom of Prussia|Prussia]] and [[Austrian Empire|Austria]]. Two of those states were Napoleonic creations: the [[Kingdom of Westphalia]], which was controlled by [[Jérôme Bonaparte]], the Emperor's youngest brother; and the [[Grand Duchy of Würzburg]] as was Poland, then the [[Duchy of Warsaw]].

During the [[Peninsular War|French invasion of the Iberian Peninsula]], Napoleon attempted to subjugate Portugal and Spain into a client [[Spain under Joseph Bonaparte|Kingdom of Spain]], but the French were eventually driven out of Iberia in a costly war.
