Shishman (Bulgarian: Шишман), also Shishmanids or Shishmanovtsi (Bulgarian: Шишмановци), was a medieval Bulgarian royal dynasty of partial Cuman origin. The Shishman dynasty consecutively ruled the Second Bulgarian Empire for approximately one century, from 1323 to 1422, when it was conquered by the Ottomans. The Shishmanids were related to the earlier Asen dynasty, and according to the Ragusan historian Lukarić, also to the immediately preceding Terter dynasty. In Plamen Pavlov's view, the Shishman dynasty's founder, despot Shishman of Vidin, may have been the brother of George I, the first Bulgarian Terterid ruler, thus also coming to Bulgaria from the Kingdom of Hungary after 1241.
