Answer
The Medici family, a prominent Italian family that ruled Florence during the Renaissance, had two main branches: the senior branch of the grand dukes of Tuscany and the junior branch known as the "Popolani" or commoner Medici. Marie de' Medici, the queen consort of France and mother of King Louis XIII, belonged to the senior Medici branch, specifically the branch that had acquired the title of grand dukes of Tuscany.
