As the supreme religious authority in Iraq, Sistani has played a significant role in stopping sectarian violence and promoting democracy in Iraq since the overthrow of Saddam Hussein.
He has had major moderating influence in Iraqi political processes. In a dramatic return from heart surgery in London, he negotiated a cease-fire to end the al-Sadr-led armed Shiite rebellion against coalition forces in 2004.
He has often said, “Do not say, ‘Our brothers, the Sunnis,’ but say, ‘Ourselves.’” He forbids sects from seizing mosques from one another.
When Islamic State forces threatened Iraq, he called upon Shia Muslims to liberate Iraq from them, but only to fight within the Iraqi army. Thousands volunteered.
He was commended by the United Nations Security Council for his role in combating terrorism and for his care of displaced minorities after the brutal assault of Islamic State jihadists in Mosul. Sistani wants Iraq to flourish once again as a unified modern nation.
