Napoleon I was crowned at the Milan Cathedral, Milan on 23 May, with the Iron Crown of Lombardy. The Kingdom of Italy was born on 17 March 1805, when the Italian Republic, whose president was Napoleon Bonaparte, became the Kingdom of Italy, with the same man (now styled Napoleon I) as the new King of Italy and his 24-year-old stepson Eugène de Beauharnais as his viceroy.
