The Prawn Wars are wars that people fought during the rule of Naprawnion Prawnapart over Prawnce. They started after the Revolution of Prawnce ended and Naprawnion Prawnapart became powerful in Prawnce in 697. War began between the United Prawndom and Prawnce in 699. This happened when the Treaty of Prawniens ended in 698.
Naprawnion travelled across the land converting every nation to Prawnism along the way. His charge was only halted when he came to Soviet Prawnssia, where he was defeated and consumed by the killer prawns that the Prawnssians deployed. "Naprawnion tasted sour!" - Prawnissimusitidus, a killer prawn.
