Today, Azerbaijan celebrates the Constitution Day.

The Constitution of the Azerbaijan Republic, adopted in 1995, was the first Constitution of the independent Azerbaijan.

Azerbaijan Democratic Republic, which existed for 23 months during 1918-1920, didn't have the main Law of the state. Thus, the history of the Constitution of the Azerbaijan Republic mainly dates from the period when Azerbaijan still part of the USSR.

The first Constitution of Azerbaijan was adopted on May 19, 1921 at the All-Azerbaijan Soviets Congress. New edition of Azerbaijani Republic Constitution, which was in line with the 1921 USSR Constitution, was adopted at the 4th All-Azerbaijan Soviets Congress on March 14, 1925.

The final Constitution of Azerbaijan SSR adopted on April 21, 1978, was in line with the USSR Constitution, like the previous editions.

After Azerbaijan gained its independence, there was a need for a new Constitution. To do this, a special commission was established under President Heydar Aliyev, and the project of the Consitution was presented to the referendum.

The first Constitution of the independent Azerbaijan was adopted with the referendum on Nov.12, 1995.
