List of Famous people named Cosimo

Cosimo di Giovanni de' Medici, called "the Elder" and posthumously "Father of the Fatherland", was an Italian banker and politician, the first member of the Medici family which effectively ruled Florence during much of the Italian Renaissance. Despite his influence, his power was not absolute; Florence's legislative councils at times resisted his proposals throughout his life, and he was viewed as first among equals, rather than an autocrat. His power derived from his wealth as a banker, and he was a patron of arts, learning and architecture.

Cosimo I de' Medici was the second Duke of Florence from 1537 until 1569, when he became the first Grand Duke of Tuscany, a title he held until his death.

Cosimo II de' Medici was Grand Duke of Tuscany from 1609 until his death. He was the elder son of Ferdinando I de' Medici, Grand Duke of Tuscany, and Christina of Lorraine.

Cosimo III de' Medici was the penultimate (sixth) Medici Grand Duke of Tuscany. He reigned from 1670 to 1723, and was the elder son of Grand Duke Ferdinando II. Cosimo's 53-year-long reign, the longest in Tuscan history, was marked by a series of ultra-reactionary laws which regulated prostitution and banned May celebrations. His reign also witnessed Tuscany's deterioration to previously unknown economic lows. He was succeeded by his elder surviving son, Gian Gastone, when he died, in 1723.

Cosimo Morelli was an Italian architect, active throughout the Papal States in a Neoclassic style.
