The Congress of Estonia was an innovative grassroots parliament established in Estonia as a part of the process of regaining of independence from the Soviet Union. It also challenged the power and authority of the pre-existing quasi-parliament in the country, called the Supreme Soviet of the Estonian SSR, which had been imposed on Estonia after Moscow's illegal annexation in 1940. The Congress of Estonia declared that it represented the highest authority on questions of Estonian statehood and citizenship, deriving this authority from the consent and initiative of the citizens of Estonia. The aim of the Congress was to restore Estonian independence based on the principle of legal continuity, with the pre-1940 republic of Estonia, which had been established in 1918, as the foundation.
