Answer
Phocas dealt with domestic opposition with increasing ruthlessness. After he took power, he executed several high-ranking officials, including the former emperor Maurice and his six sons. Phocas also persecuted the Monophysites, who were a religious minority in the Byzantine Empire. He executed several prominent Monophysites and destroyed their churches. Phocas's ruthlessness alienated many people in the Byzantine Empire, and his rule was eventually overthrown by the army.
