Rizzardo IV da Camino
Rizzardo IV da Camino (1274–1312) was an Italian condottiero and lord of Treviso. Knighted in 1295 by Azzo VIII d'Este, he succeeded his father Gherardo III in 1306. He long led the family's expansion into Friuli: in 1309 he escorted the patriarch of Aquileia home and extorted the title of captain general, only to be driven out by a citizen uprising.
In 1311 he joined the Ghibellines and became imperial vicar under Henry VII, alienating Venice. In April 1312 he was stabbed at chess in his palace and died a week later.
