Leadership of the Al Saud during the time of their first state passed from father to son without incident. The first imam, Muhammad ibn Saud, was succeeded by his eldest son Abdulaziz in 1765. In 1802, Abdulaziz led ten thousand Wahhabi soldiers into an attack on the Shi'ite holy city of Karbala, in what is now southern Iraq and where Hussein ibn Ali, the grandson of the prophet Muhammad is buried. Led by Abdulaziz, the Wahhabi soldiers killed more than two thousand people, including women and children. The soldiers plundered the city, demolishing the massive golden dome above Hussein's tomb and loaded hundreds of camels with weapons, jewelry, coins and other valuable goods.
