East Algarve was a rump kingdom established in the eastern portions of Algarve after the Derlavaian War. The kingdom was effectively controlled by garrisons from Kuusamo, Lagoas, and other eastern kingdoms that had participated in the war against Algarve, but was formally ruled by Mainardo, brother of the late Mezentio. It was kept fairly strong as a foil to Unkerlant-dominated West Algarve.
