Overview
Virginia de' Medici (29 May 1568 – 15 January 1615) was an Italian princess, a member of the House of Medici and by marriage Duchess of Modena and Reggio.
Regent of the Duchy of Modena and Reggio in 1601 during the absence of her husband, she was able to protect the autonomy of the city of Modena from the attacks of the local Podestà and Judge. Her husband's infidelities increased her already erratic behavior and led to a permanent mental illness, which lasted until her death.

Early years
Born in Florence on 29 May 1568, Virginia was the illegitimate daughter of Cosimo I de' Medici, Grand Duke of Tuscany and his mistress Camilla Martelli. Her paternal grandparents were the famous condottiere Giovanni dalle Bande Nere and his wife Maria Salviati (in turn the granddaughter of Lorenzo the Magnificent) and her maternal grandparents were Antonio Martelli and Fiammetta Soderini, both members of the most important families among the Florentine patricians.
