 They established a "Dodici" (council of 12 nobles), assisted by a council with a popular majority.This form of government was also short-lived, soon replaced by the "Quindici" ("The Fifteen") reformers in 1385, the "Dieci" ("The Ten", 1386–1387), "Undici" ("The Eleven", 1388–1398) and the Twelve Priors (1398–1399) who, in the end, gave the city's lordship to Gian Galeazzo Visconti, the Duke of Milan, in order to defend it from Florentine expansionism.Five years later, the House of Visconti was expelled in 1404, and a new government of Ten Priors was established, this time in alliance with Florence against King Ladislaus of Naples.
