"Muqtada belongs to the most famous religious family in Iraq, which is the al-Sadr family. He's really the third in line. [Muqtada's father] drew his power from the first really important al-Sadr, Muhammad Baqir, who was executed by Saddam in 1980, together with his sister. So it's really a family of martyrs, and that's why Muqtada suddenly emerged from nowhere with the fall of Saddam."
