Cosimo III de' Medici

Cosimo III de' Medici was Grand Duke of Tuscany from 1670 until his death in 1723, the sixth and penultimate from the House of Medici. 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 laws that regulated prostitution and May celebrations. His reign also witnessed Tuscany's deterioration to previously unknown economic lows. In 1723, when Cosimo died, he was succeeded by the younger of his two surviving children, Gian Gastone.
