Medici

In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the Grand Duchy from its inception under the builder Cosimo I until 1737, with the death of Gian Gastone de' Medici. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France—Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). The Medici's grand duchy witnessed degrees of economic growth under the early grand dukes, but was bankrupt by the time of Cosimo III de' Medici (r. 1670–1723).
