The Kingdom of Italy (1805–1814; ; ) was a kingdom in Northern Italy (formerly the Italian Republic) in personal union with Napoleon I's French Empire. It was fully influenced by revolutionary France and ended with Napoleon's defeat and fall.

The second one, dating from 29 March, regulated the regency, the Great Officials of the kingdom, and the oaths. The most important was the third, proclaimed on 5 June, being the real constitution of the kingdom: Napoleon I was the head of state and had the full powers of government; in his absence, he was represented by the Viceroy, Eugène de Beauharnais. The Consulta, Legislative Council, and Speakers were all merged into a Council of State, whose opinions became only optional and not binding for the king. The Legislative Body, the old parliament, remained in theory, but it was never summoned after 1805; the Napoleonic Code was introduced.
