Before the Greek Dark Ages , Thessaly was known as Aeolia , and appears thus in Homer ' s " Odyssey ".

He was a descendant of John Doukas ( c . 1126 -- c . 1200 ) son of Constantine Angelos by Theodora Komnene , daughter of the Byzantine Emperor Alexios I Komnenos and Irene Doukaina , hence the combination of family names , `` Angelos Komnenos Doukas '' . ___MASK95___ (' ), officially the Hellenic Republic ( Greek : ' ), historically also known as Hellas ("" ), is a country in southeastern Europe . ___MASK95___ ' s population is approximately 10 . 955 million as of 2015 . ___MASK99___ is the nation ' s capital and largest city , followed by Thessaloniki . The ___MASK29___ , also referred to as the Eastern Roman Empire , was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages , when its capital city was Constantinople ( modern - day Istanbul , which had been founded as Byzantium ). It survived the fragmentation and fall of the ___MASK72___ in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453 .

After the 12th century , the name " Doukas " and other variants proliferated across the Byzantine world , and were sometimes presented as signifying a direct genealogical relationship with the original family or the later branch based in the ___MASK84___ . Homer (, " Hómros ") is the name ascribed by the Ancient Greeks to the semi - legendary author of the two epic poems , the " Iliad " and the " Odyssey ", the central works of Greek literature .

An angel , especially according to Abrahamic religions and Zoroastrianism , is a spiritual being superior to humans in power and intelligence . Angels are typically described as benevolent , dreadful , and endowed with wisdom and knowledge of earthly events , but not infallible ; for they strive with each other , and God has to make peace between them .

It claimed to be the legitimate successor of the Byzantine Empire , along the Empire of Nicaea and the Empire of Trebizond . The term " ___MASK84___ " is , like " Byzantine Empire " itself , a modern historiographic convention and not a name in use at the time . 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 . The family name means " angel " ( messenger of God ).
