What was the ratification process of the Iraq constitution?

The ratification process of the Iraq constitution took place in 2005, following the approval of the draft by the National Assembly. A referendum was held on October 15, 2005, where the constitution was approved by a majority of voters, with around 78% in favor. However, it faced opposition, particularly from Sunni Arab groups, leading to a requirement that any province could reject the constitution if two-thirds of voters opposed it. Ultimately, the constitution was adopted, marking a significant step in Iraq's political transition after the 2003 invasion.
