Isabella of France (Château de Bois de Vincennes, 1 October 1348 – Pavia, 11 September 1373) was a French princess and member of the House of Valois, as well as the wife of Gian Galeazzo Visconti, Lord of Milan, although she died before her husband's accession).
This was also short-lived, being replaced by the Quindici (Fifteen) reformers in 1385, the Dieci (Ten, 1386–1387), Undici (Eleven, 1388–1398) and Twelve Priors (1398–1399) who, in the end, gave the city's seigniory to Gian Galeazzo Visconti of Milan in order to defend it from the Florentine expansionism.
