Constantine Akropolites or Acropolites, son of the scholar and statesman George Akropolites, was a minister of the Byzantine emperor Michael VIII Palaiologos, until the Emperor dismissed him for his opposition to the union of churches created by the Second Council of Lyon (1272). Under the new emperor Andronikos II, however, Akropolites returned to favor; perhaps as early as 1282 he was appointed Logothete, and on the death of Theodore Mouzalon in 1294, Akropolites was raised to the title of megas logothetes, which he held perhaps as late as 1321. He died sometime before August 1324, for a document dated May–August 1324, concerning the Monastery of the Anastasis, states he is dead.
Constantine of Kostenets, also known as Constantine the Philosopher, was a medieval Bulgarian scholar, writer and chronicler, who spent most of his life in the Serbian Despotate. He is best known for his biography of Serbian despot Stefan Lazarević, which George Ostrogorsky described as "the most important historical work of old Serbian literature", and for writing the first Serbian philological study, Skazanije o pismeneh. He followed the writing style of the Old Serbian vita, first made popular in the Serbian scriptoria of the 12th century.
Constantine of Preslav was a medieval Bulgarian scholar, writer and translator, one of the most important men of letters working at the Preslav Literary School at the end of the 9th and the beginning of the 10th century. Biographical evidence about his life is scarce but he is believed to have been a disciple of Saint Methodius. After the saint's death in 885, Constantine was jailed by the Germanic clergy in Great Moravia and sold as slave in Venice. He escaped to Constantinople, moving to Bulgaria around 886 and working at the Preslav Literary School.
Konstantinos Petrou Kavafis, known, especially in English, as Constantine P. Cavafy and often published as C. P. Cavafy, was a Greek poet, journalist, and civil servant from Alexandria. His work, as one translator put it, "holds the historical and the erotic in a single embrace."
Constantine I, also known as Constantine the Great, was Roman emperor from AD 306 to 337. He was the first emperor to convert to Christianity. Born in Naissus, Dacia Mediterranea, he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek woman of low birth and a Christian. Later canonized as a saint, she is traditionally attributed with the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces before being recalled in the west to fight alongside his father in the province of Britannia. After his father's death in 306, Constantine was acclaimed as augustus (emperor) by his army at Eboracum. He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.
Constantine VII Porphyrogenitus was the fourth Byzantine emperor of the Macedonian dynasty, reigning from 6 June 913 to 9 November 959. He was the son of Emperor Leo VI and his fourth wife, Zoe Karbonopsina, and the nephew of his predecessor Alexander.
