Theodore, or Theodoros (Θεόδωρος) II Laskaris (Λάσκαρις) was a Nikaian emperor of the 13th century. He was known for his intellectual prowess and production of theological, historical, and philosophical treatises. He wrote Egkomion (Εγκωμιον) as a praise of the Nikaians and also treatises against Catholic positions. These were called, "First Oration against the Latins" and "On the Trinity". He repelled the Mongols and Bulgarians and ceded Dyrrachium from the Epeiros rump state. He also discussed the possibility of church union, once again, with Pope Alexander IV but a union never occurred.
