Lieutentant-Colonel Ibrahim al-Hamdi (1943–October 11, 1977) was the leader of a military coup d'etat in Yemen Arab Republic that overthrew the regime of President Abdul Rahman al-Iryani on June 13, 1974. After the revolt, he was President of the Military Command Council that governed the country. During his rule, he cemented the central government's control over the country, planned on ending tribal loyalty, and Yemen's medieval "social classes" by proclaiming all Yemenis as equal, and improved relations with Saudi Arabia and the United States. He also planned on improving ties with Marxist People's Democratic Republic of Yemen, but he was assassinated by Saudi Arabian agents who were ultimately against his rebuilding of Yemen, before he could make the trip to Aden. Many Yemenis agree he was the country's most beloved leader to date.
