[5] On 9 November 1918 on the basis of the proposal by Mammad Amin Rasulzadeh the three-color flag of the Azerbaijan Democratic Republic was adopted.

The Azerbaijan Democratic Republic was able to operate in a tense and complicated socio-political situation for only 23 months.

So far only a geographical reference, Azerbaijan now became the name of a state, and some 2 million people, called variously Tatars, Transcaucasian Muslims, and Caucasian Turks, officially became Azerbaijanis.

[10] One year after the founding of the ADR, a military parade on the site of the Azerbaijan Carpet Museum took place on Republic Day.

[14] In 2001, Patriarch Alexy II of Moscow visited the country for the first time to attend the Republic Day celebrations.

However, after the Republic gained independence for the second time, the name, reminiscent of the Soviet past, was replaced by "May 28".
