History of Italy
In 1805, after the French victory over the Third Coalition and the Peace of Pressburg, Napoleon recovered Veneto and Dalmatia, annexing them to the Italian Republic and renaming it the Kingdom of Italy. Also that year a second satellite state, the Ligurian Republic (successor to the old Republic of Genoa), was pressured into merging with France. In 1806, he conquered the Kingdom of Naples and granted it to his brother and then (from 1808) to Joachim Murat, along with marrying his sisters Elisa and Paolina off to the princes of Massa-Carrara and Guastalla. In 1808, he also annexed Marche and Tuscany to the Kingdom of Italy.
