Baku:November 12 is celebrated as Constitution Day in Azerbaijan, commemorating the adoption of the country's first independent constitution in 1995 through a national referendum. This significant event laid the foundation for state-building in independent Azerbaijan.

According to Azeri-Press news agency, the Constitution was adopted by referendum on November 12, 1995, and came into effect on November 27, 1995. It marked the first Constitution of independent Azerbaijan and the fourth in the country's history. The Azerbaijan Democratic Republic (1918-1920) did not adopt a state constitution during its brief existence.

The constitutional history of Azerbaijan dates back to the Soviet era, with the first Constitution adopted in 1921 and revised versions aligning with the USSR Constitution adopted in 1925 and 1978. Following the country's independence, President Heydar Aliyev led efforts to draft a new Constitution, which was then subjected to public discussion before being adopted by referendum.

The 1995 Constitution of Azerbaijan comprises 5 sections, 12 chapters, and 158 articles. It has undergone amendments and additions through referendums in 2002, 2009, and 2016. The Constitutional Court of Azerbaijan, established on July 14, 1998, serves as the country's first body for constitutional judicial review. Despite the significance of Constitution Day, November 12 remains a working day in Azerbaijan.
