Giovanni de' Rossi (21 November 1431[1] – 1502) was an Italian condottiero and the fifth count of San Secondo.
Giovanni was thus exiled with nothing and entered the service of the king of France, though he continued to claim the inheritance which had been denied him.
[2] When Pier Maria II died on 1 September 1482 in the midst of the Rossi War against Sforza troops under Ludovico il Moro and Pier Maria II's own son Guido, the succession became even more tangled.
He attempted a last-ditch defence of the castle at San Secondo in 1483 before fleeing to Venice, where he died in exile in 1490.
The conflict provoked by Pier Maria II's will was finally fully resolved by the Battle of San Secondo in 1522.
