Piero degli Albizzi

Piero degli Albizzi (died 1379) was a leading Guelph politician in fourteenth-century Florence. He was prior in 1349–1350, and in 1358 the commissioner charged with defending Florentine land against the raids of the mercenary Count Lando.

In 1370, at the height of his career, he persuaded the councils to move against the Visconti. His feud with the Ricci, led by Uguccione, ended in 1372 with both men barred from office and exiled; Piero took refuge at Queen Joanna I's Naples court and returned in 1377 to the Guelph leadership.

In July 1378 the Ciompi revolt burned the Albizzi houses, and he fled to Venice. Arrested in Florence on 20 December 1379 on a charge of plotting against the popular regime, he was beheaded in the Palazzo della Signoria three days later.
