A constitutional referendum was held in Somaliland on 31 May 2001, an internationally recognized autonomous region in Somalia. The referendum was held on a draft constitution that affirmed Somaliland's independence from Somalia as a separate state. Two-thirds of eligible voters took part in the referendum and 97.1% of them voted in favour of the constitution. However the referendum was opposed by the Government of Somalia and did not lead to any international recognition of Somaliland's separatism.
In May 1991 after the fall of the military dictator of Somalia, Siad Barre, the Somali National Movement declared the independence of Somaliland. In 1993 an executive presidency was set up with a bicameral legislature and Muhammad Haji Ibrahim Egal was elected president by a council of elders. In 1997, at a Conference of Somaliland Communities in Hargeisa, a constitution was adopted to last for 3 years until a referendum could take place to bring it into full effect. The constitution was amended in 2000 and the referendum was delayed by one year till 2001. Meanwhile, the attempts to form a national government of Somalia and the formation of the Transitional National Government of Somalia in May 2000 encouraged Somaliland to hold a referendum to try to show Somaliland's desire for independence.
The referendum in effect became a vote on the independence of Somaliland due to the inclusion in the constitution of a clause on Somaliland's independence. There was no census or voter lists so community elders decided who was eligible to vote in the referendum.
The Transitional Federal Government of Somalia opposed the referendum, describing it as illegal and said that the government of Somaliland had no authority to unilaterally separate from Somalia. The referendum was also opposed by the leadership of the neighbouring region of Puntland as provocative. No international organisation or country supported the referendum.
