The Bastard's Rebellion was a military conflict that took place in the Duchy of Athens in 1402 and 1403. A Florentine by the name of Antonio I Acciauoli managed to recapture his title and the Duchy from the Venetians. Angered by this, the Venetians retaliated, blockading Athenian ports and sending in troops. The Roman Empire also participated, lured in by its increasing relations with Venice due to the Treaty of Aegina and the promise of land.
