The rulers of Tuscany have varied over time, sometimes being margraves, the rulers of handfuls of border counties and sometimes the heads of the most important family of the region.
Tuscany was annexed by France, 1807-1814. Napoleon's sister Elisa Bonaparte was given the honorary title of Grand Duchess of Tuscany, but did not actually rule over the region.
