A "wise and aware" princess, Anna Maria was given in marriage to John Charles Wilhelm I of Austria when she was still very young, but despite moving to Dusseldorf she kept having an influence over her father Cosimo, who named her heir of her brother Gian Gastone. Anna Maria moved back to Florence in 1717 after the death of her husband. She died in 1743, and she was buried in the Cappelle Medicee.
