21 september, Independence day of Armenia
Wikipedia..
On March 17, 1991, Armenia, along with the Baltics, Georgia and Moldova, boycotted a union-wide referendum in which 78% of all voters voted for the retention of the Soviet Union in a reformed form.[36] On August 23, 1991, Armenia became one of the first republics to declare independence from the Soviet Union. Armenia’s desire to break away from the Soviet Union largely stemmed from Moscow’s intransigence on Karabakh, mishandling of the earthquake relief effort, and the shortcomings of the Soviet economy.[citation needed]
On September 21, 1991, Armenia declared its independence. Tensions between Armenia and Azerbaijan continued to escalate, ultimately leading to the outbreak of the Nagorno-Karabakh War. Despite a cease-fire in place since 1994, Armenia has yet to resolve its conflict with Azerbaijan over Nagorno-Karabakh. The country, however, has seen substantial development since independence, moving away from a planned economy to a privatized one and adopting a representative democratic system of government. Armenia remains blockaded by both Turkey and Azerbaijan over the Karabakh dispute. It maintains friendly relations with its neighboring states of Georgia and Iran and is a strategic ally of Russia.
On July 5, 1995, the new constitution of the Republic of Armenia was adopted.
