The most important historical figure in Somali history is Muhammad 'Abdallah bin Hasan (known popularly in English literature as the "Mad Mullah"). He was born about 1860 and during his youth devoted himself to religious studies. In August 1899, with his followers of the Salihiyyah confraternity, he declared a holy war against the British, Italians, and Ethiopians. His resistance to the British lasted until his death in November 1920. Muhammad, also known as one of Somalia's greatest poets, was the first to call for Somali unity. Other important historical figures include Sharif Abu Bakr bin 'Abdallah al-'Aydarus (d.1503), who founded the Qadiriyyah confraternity in the Somali region; Sheikh 'Ali Maye Durogba of Marka (d.1917), who founded the Ahmadiyyah sect in Somalia; and Sheikh Muhammad Guled (d.1918), who started the Salihiyyah sect in Somalia.
'Abdullahi 'Issa Mohamud (b.1921) was prime minister during the Italian trusteeship administration (1956–60) and was Somalia's first foreign minister. Aden 'Abdullah Osman Daar (b.1908) is regarded as the Somali most responsible for bringing about the transition of the Somali territory from dependence to independence; he was the nation's first president. Abdirashid 'Ali Shermarke (1919–69) was Somalia's first prime minister after independence and the nation's second president. He was assassinated on 15 October 1969 by a member of his bodyguard. Maj. Gen. Jalle Mohamed Siad Barre (1921–95) was the leader of the bloodless coup that took over the government six days later and established the SRC. He subsequently became president of the Somali Democratic Republic. Mohamed 'Ali Samater (b.1931), first vice-president and minister of defense, became prime minister in 1986. Mohammed Farah Aidid (1934–96) was the clan leader that gained control over much of Somalia during the civil war. His son, Hussein Aidid (b.1962), a former US marine, took over after his death. Osman Hasan Ali (b.1950) became famous as the wealthy financier of clan militias during the civil war.
May Allah Bless Somalia forever.
