Empire of Nicaea, Empire of Trebizond, and the Despotate of Epirus 1204
After the sack of Constantinople in 1204 by Latin Crusaders, two Byzantine successor states were established: the Empire of Nicaea, and the Despotate of Epirus. A third one, the Empire of Trebizond was created a few weeks before the sack of Constantinople by Alexios I of Trebizond.
