The second independence
Seven decades later the idea of 1918 returned. In 1991 Azerbaijan restored its state independence and declared itself the successor of the first republic.
The revival of independence in 1991 was a direct continuation of the work of the ADR. The new republic stressed that it inherited the statehood of 1918.
1991 · Revival
On 30 August 1991 the Declaration on the Restoration of State Independence was adopted, and on 18 October the Constitutional Act on the State Independence of the Azerbaijan Republic.
That act directly mentioned the 1918 Declaration and the succession from the Azerbaijan Democratic Republic — the bond of two eras was set down in writing.

The main dates of Azerbaijan's path to independence.
1991 · Revival
Modern Azerbaijan considers itself the direct heir of the ADR: the same flag, the same symbols, the same idea of freedom and national dignity.
So the two independences — of 1918 and 1991 — joined into the single history of one country.
