Zanj Rebellion
The marshes had for some time been considered a refuge for elements persecuted by the government of Saddam Hussein, as in past centuries they had been a refuge for escaped slaves and serfs, such as during the Zanj Rebellion. By the mid-1980s, a low-level insurgency against Ba'athist drainage and resettlement projects had developed in the area, led by Sheik Abdul Kerim Mahud al-Muhammadawi of the Al bu Muhammad under the "nom de guerre" Abu Hatim.
