Overview
Maria Salviati (17 July 1499 – 29 December 1543) was a Florentine noblewoman, the daughter of Lucrezia di Lorenzo de' Medici and Jacopo Salviati. She married Giovanni delle Bande Nere and was the mother of Cosimo I de Medici. Her husband died 30 November 1526, leaving her a widow at the age of 27. Salviati never remarried; after her husband's death she adopted the somber garb of a novice, which is how she is remembered today as numerous late portraits show her attired in black and white.
Life
Maria Salviati was born in Florence. She descended from two of Florence's most powerful banking families: the Salviati on her father's side, and the de' Medici on her mother's. Her maternal grandfather was Lorenzo "il Magnifico".
When her cousin, Alessandro de' Medici was assassinated in 1537, Maria used her family connections to get involved in the discussions to decide the next Duke of Florence. She played a key role in getting her son, Cosimo I de' Medici, elected.
