Information: - The Empire of Trebizond or the Trapezuntine Empire was a monarchy that flourished during the 13th through 15th centuries, consisting of the far northeastern corner of Anatolia and the southern Crimea. Originally formed during a revolt against the usurpation of the imperial throne by the grandsons of Emperor Andronikos I Komnenos, Trebizond (current Trabzon, Turkey, with which the name of the empire is a cognate) became a Byzantine Greek successor state established after the fall of the Eastern Roman Empire (Byzantine) in the Fourth Crusade, along with the Empire of Nicaea and the Despotate of Epirus. The Emperors of Trebizond pressed their claim on the Imperial throne for decades after the Nicaean reconquest of Constantinople in 1261. - The Empire of Nicaea was the largest of the three Byzantine Greek successor states founded by the aristocracy of the Byzantine Empire that fled after Constantinople was occupied by Western European and Venetian forces during the Fourth Crusade.

History. It was founded between 650 and 625 BC by Gorgus, son of the Corinthian tyrant Cypselus, at which time its economy was based on farmlands, fishing, timber for shipbuilding, and the exportation of the produce of Epirus. After the expulsion of Gorgus's son Periander its government developed into a strong democracy. The early policy of Ambracia was determined by its loyalty to Corinth (for which it probably served as an entrepot in the Epirus trade), and its consequent aversion to Corcyra (as Ambracia participated on the Corinthian side at the Battle of Sybota, which took place in 433 BC between the rebellious Corinthian colony of Corcyra (modern Corfu) and Corinth). - The Angelos family, feminine form Angelina, plural Angeloi, was a Greek noble lineage which gave rise to three Byzantine emperors who ruled between 1185 and 1204. From the 13th to the 14th century, a branch of the family ruled Epiros, Thessaly and Thessaloniki under the name of Komnenos Doukas.

During the latter tenure he rebelled against Alexios III but was defeated and forced to flee to the Seljuk Turks .

Michael 's domain in Epirus became a refuge and centre of resistance of the Greeks against the Latin Crusaders . At about the same time , according to some modern scholars , he may have led the abortive Greek resistance to the Crusaders in the Peloponnese , which was crushed at the Battle of the Olive Grove of Kountouras ; according to other views , he may have led a campaign there between 1207 and 1209 . In order to avoid invasion and buy time to consolidate his position in Epirus , Michael soon entered into negotiations with Pope Innocent III , and concluded treaties with the Latin Empire and the Republic of Venice . In the meantime , his rule received legitimacy when he ransomed the deposed Alexios III from captivity . According to later chroniclers , Alexios III conferred the hereditary rule of Epirus to Michael and his descendants . By 1210 , Michael was secure enough to launch an attack against the Latin Kingdom of Thessalonica , in conjunction with the Bulgarians .... - Doukas, Latinized as Ducas (feminine: Doukaina/Ducaena, ; plural: Doukai/Ducae, ), from the Latin tile "dux" ("leader", "general", Hellenized as ["oux"]), is the name of a Byzantine Greek noble family, whose branches provided several notable generals and rulers to the Byzantine Empire in the 9th11th centuries.

It is roughly 160km long, with a maximum elevation of 2,637m (Mount Smolikas). Because it runs along the border of Thessaly and Epirus, the Pindus range is often called the "spine of Greece".
