1989 Iranian constitutional referendum

A constitutional referendum was held in Iran on 28 July 1989, alongside presidential elections. Approved by 97.6% of voters, it was the first and so far only time the Constitution of the Islamic Republic of Iran has been amended. It made several changes to articles 5, 107, 109, 111, and added article 176. It eliminated the need for the Supreme Leader ("rahbar") of the country to be a "marja" or chosen by popular acclaim, it eliminated the post of prime minister, and it created a Supreme National Security Council.
