Every year, Azerbaijan marks the national holiday, the Republic Day.

The 20th century became known in history not only as the age of science and technology, but also as the age of liberation from colonization and the establishment of national states.

The 1917 Russian Revolution put an end to the rule of the Romanovs and saw the collapse of the Russian Empire. Shortly thereafter, on May 28, 1918, patriotic leaders in Azerbaijan founded the Democratic Republic of Azerbaijan.

The Azerbaijani Democratic Republic was the first democratic republic to be established in the East. It was a parliamentary state, with all the associated attributes. It had a flag, an anthem and an army.

The Azerbaijani Democratic Republic existed only 23 months. On April 28, 1920 the Bolcheviks 11th Army occupied Azerbaijan and the republic collapsed.

The Republic Day - the day of regaining state independence, has been celebrated as a state holiday since 1990.
