One major Shia militia in Iraq is the Badr Organization, the military wing of the Supreme Islamic Council of Iraq. The group is currently based in Karbala, Iraq, and is also active in areas throughout southern Iraq. The group was formed by the Iranian Government to fight the Saddam Hussein-controlled Iraq during the Iran–Iraq War. Originally, the group consisted of Iraqi exiles who were banished from Iraq during the reign of Saddam Hussein. After the war ended in 1988, the organization remained in Iran until Saddam Hussein was overthrown during the 2003 invasion of Iraq. Following the invasion, the brigade then moved into Iraq, became members of the new Iraq Army, and aided coalition forces in insurgents.
