Eric III (9 June 1637 – 12 October 1701), known as Eric the Great (Greek: Έρικ τις Μέγας; French: Éric le Grand) or the Sun Emperor (Greek: Ήλιος Αυτοκράτορας/Helios Autokrator; French: Le Soleil empereur), was a monarch of the House of Komnenos-Palaiologos who ruled as Emperor of all Diadochia from 1647 until his death. He reigned for 54 years. Eric began his personal rule in 1659, when he turned twenty-two years old, right after the regent Victor Angelos died.
