Basil Vatatzes

[4] 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.

This time Vataztes effectively ended the rebellion and forced the usurper to flee to the court of the Seljuk Turks at Iconium.

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.

[8] He married a daughter of Isaakios Angelos and was likely[11][12] 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.
