arie de Medici (1573-1642), daughter of
Francis, grand-duke of Tuscany, married (1600) Henry IV of France.
After the murder of her husband by Ravaillac, she was appointed
queen-regent, but allowed herself to be governed by two
Florentine adventurers, Concini and his wife Leonora, until the
young king, Louis XIII, caused Concini to be assassinated, and
exiled Mary to Blois, whence she made her escape to Angoulême in
1617. [World Wide Illustrated Encyclopedia, 1935]
