Latins (Middle Ages) in the context of "Latin Emperor"

The Latin Emperor was the ruler of the Latin Empire, the historiographical convention for the Crusader realm, established in Constantinople after the Fourth Crusade (1204) and lasting until the city was reconquered by the Byzantine Greeks in 1261. Its name derives from its Catholic and Western European ("Latin") nature. The empire, whose official name was Imperium Romaniae (Latin: "Empire of Romania"), claimed the direct heritage of the Eastern Roman Empire, which had most of its lands taken and partitioned by the crusaders. This claim however was disputed by the Byzantine Greek successor states, the Empire of Nicaea, the Empire of Trebizond and the Despotate of Epirus. Out of these three, the Nicaeans succeeded in displacing the Latin emperors in 1261 and restored the Byzantine Empire.

Theodore I Komnenos Laskaris or Lascaris (Greek: Θεόδωρος Κομνηνὸς Λάσκαρις, romanized: Theodōros Komnēnós Láskaris; c. 1175 – November 1221) was the first emperor of Nicaea—a successor state of the Byzantine Empire—from 1205 to his death. Although he was born to an obscure aristocratic family, his mother was related to the imperial Komnenos clan. He married Anna, a younger daughter of Emperor Alexios III Angelos in 1200. He received the title of despot before 1203, demonstrating his right to succeed his father-in-law on the throne.

The Fourth Crusade forced Alexios III to flee from Constantinople in 1203. Theodore was imprisoned by the crusaders (commonly referred to as "Latins" by the Byzantines), but he escaped. After crossing the Bosporus into Asia Minor (in present-day Turkey), he started to organise the local Greeks' resistance against the Latins in Bithynia in his father-in-law's name. He concluded an alliance with the Seljuq sultan of Rum, but he could not stop the Latins' expansion. Neither could he prevent a claimant to the imperial throne, Alexios Komnenos, from establishing a Byzantine successor state, the Empire of Trebizond, in northern Asia Minor. Theodore's position consolidated only after Tzar Kaloyan of Bulgaria inflicted a crushing defeat on the Latins in the Battle of Adrianople (in Thrace) in 1205.

The House of Tocco (pl. Tocchi, Ancient Greek: Τόκκος, romanized: Tókkos pl. Τόκκοι, Tokkoi) was an Italian noble family from Benevento that came to prominence in the late 14th and 15th centuries, when they ruled various territories in western Greece as Counts Palatine of Cephalonia and Zakynthos and Despots of Epirus. During their brief period of rule in Greece, they were one of the most ambitious and able Latin dynasties in the region, and were one of the few to leave descendants lasting nearly until modern times, in which they claimed to represent the senior matrilineal heirs of the Palaiologos dynasty.

The earliest known members of the family are recorded in the 12th century, in Benevento, though Tocco family genealogies claimed that they originated much earlier, with forged connections to ancient Gothic kings Theodoric the Great and Totila, as well as to the ancient Epirote king Pyrrhus. Members of the family held various prominent offices during the rule of the Hohenstaufen and Angevin dynasties in the Kingdom of Sicily. As a result of the family's loyalty to the Angevin princes in Greece, such as the titular Latin emperors Philip I of Taranto and Robert of Taranto, Leonardo I Tocco was rewarded c.  1357 with the grant of the County Palatine of Cephalonia and Zakynthos, islands off the western coast of Greece.
