Mohamed Siad Barre (October 6, 1919 - January 2, 1995) was a Somali politician, military officer, and author who served as the President of Somalia from 1969 to 1991, making him the longest-serving leader in modern Somali history. He rose to power through a military coup in 1969 and established the Somali Democratic Republic. During his 22-year rule, Barre implemented socialist policies, maintained close ties with the Soviet Union, and championed linguistic reform by developing a Latin-script writing system for the Somali language. His regime collapsed in 1991 during the Somali Civil War, and he died in exile in Nigeria.
