Bahram Chobin (died 591 AD) was a famous Sasanian general from the noble House of Mihran. He gained fame by crushing a massive Gokturk invasion in the east with a small but elite force.
Humiliated by King Hormizd IV despite his victories, Bahram refused to submit and launched a rebellion, eventually seizing the capital Ctesiphon and declaring himself king (Bahram VI). This was the first time in Sasanian history that a non-Sasanian claimed the throne.
The rightful heir, Khosrow II, fled to the Byzantine Empire and returned with Roman support. Bahram was defeated at the Battle of the Blarathon in 591 and fled to the Turks, where he was later assassinated.
