Somaliland has had other constitutional documents of historical importance which range from the international treaties signed by the various Somaliland communities with the British government, and the various constitutional arrangements prior to independence in 1960 to the Declaration of Re-assertion of Sovereignty in 1991 (in Burao) at one of the earliest grand conferences of the Somaliland communities. Although the Republic of Somaliland was independent for a short period in June 1960, it later unified with Trust Territory of Somalia to form the Somali Republic. During that short period no comprehensive constitution was adopted.
