Cosimo I de' Medici (June 12, 1519 [1] – April 21, 1574) was Duke of Florence, ruling from 1537 to 1574, and became the first Grand Duke of Tuscany. Cosimo was born in Florence, the son of the famous condottiere Giovanni dalle Bande Nere from Forlì. Cosimo came to power when Alessandro de' Medici was assassinated in 1537 because Alessandro's only male issue was illegitimate. He was from a different junior branch (il Popolani) of the family.
