The Government of Iran is an Islamic theocracy which includes elements of a presidential democracy, with the ultimate authority vested in an autocratic "Supreme Leader", a position held by Ali Khamenei since Khomeini's death in 1989. The Iranian government is widely considered to be authoritarian, and has attracted widespread criticism for its significant constraints and abuses against human rights and civil liberties, including several violent suppressions of mass protests, unfair elections, and limited rights for women and children.
