Margraves reigned in the 9th century when the region was part of the
Margraviate of Tuscany. Beginning in the 11th century, the region was fully divided into several independent cities, which included
Pisa,
Florence,
Siena,
Lucca,
Arezzo among others. However, with the territorial expansion of Florence, Tuscany began to "come together" again under one single leadership. This situation became even clearer with the creation of the
Grand Duchy of Tuscany in 1569. Over the years, the Grand duchy managed to absorb practically the entire region of present-day Tuscany, until its own final annexation to the
Kingdom of Italy. ==Medici grand dukes of Tuscany, 1569–1737==
