Aaron of Bulgaria

Aaron was a younger son of the last Tsar of the First Bulgarian Empire, Ivan Vladislav. After the Byzantine conquest of Bulgaria he entered Byzantine service along with his brothers, and held a series of higher military commands in the eastern provinces of the Byzantine Empire during the 1040s and 1050s, rising from patrikios to protoproedros in the process. In this capacity, he fought in the first battles against the invading Seljuq Turks, and unsuccessfully opposed the uprising of his brother-in-law Isaac I Komnenos in 1057. The Aaronios noble family was named after him, and included his descendants, as well as the descendants of his siblings.
