Origin and early lifeEdit
Vatatzes was of low birth, hailing from the region around Adrianople and Didymoteichon. He likely entered military service under Emperor Manuel I Komnenos (r. 1143–1180), but details of his early life are otherwise unknown. He apparently reached sufficient prominence to be married, around 1187, to an unnamed daughter of Isaac Angelos Doukas, uncle to the emperor Isaac II Angelos (r. 1185–1195, 1203–1204). Married to a cousin of the emperor, Vatatzes suddenly became a member of the senior aristocracy: he was awarded the rank of sebastos, and the path to senior military commands opened to him.
Ousting of Theodore MankaphasEdit
His first office after the marriage was likely as military governor (doux) of the small province of Mylasa and Melanoudion, which he is known to have held in August 1189. From there he was promoted to "Grand Domestic of the East" and governor of the extensive Thracesian Theme.
In this capacity he had to deal with the usurper Theodore Mankaphas. Mankaphas had launched a rebellion c. 1188, when he proclaimed himself as emperor in Philadelphia. The revolt was short-lived, as Isaac II besieged the city and forced Mankaphas to submit, but the latter was pardoned and allowed to continue as governor of the city.
In c. 1192/3, however, Basil Vatatzes was sent against Theodore Mankaphas, who had rebelled once more. This time Vataztes effectively ended the rebellion and forced the usurper to flee to the court of the Seljuk Turks at Iconium.
Soon after he was appointed Domestic of the West (as with his contemporary and co-commander, Alexios Gidos, it is unclear if he was a real Grand Domestic or simply Domestic), based at Adrianople. His primary task was to confront the ongoing Bulgarian rebellion in the northern Balkans.
In 1193 he refused any military support to the rebellion of his brother-in-law Constantine Angelos Doukas, a cousin to the emperor and commander of the Byzantine armies in Philippopolis. Doukas proclaimed himself emperor and marched his troops onto Adrianople, but he was betrayed by his followers and surrendered to Isaac II Angelos for a pardon in return.
He was likely the father of John III Doukas Vatatzes, the future Emperor of Nicaea, as well as of John's two older brothers, the sebastokrator Isaac Doukas Vatatzes, and anonymous middle son, whose daughter married the protovestiarios Alexios Raoul.
