Estonian Diplomatic Service (1940–1991)
Estonia was occupied on 17 June 1940, by Red Army troops and was forcibly incorporated into the Soviet Union on 6 August 1940. The United States never recognized the illegal annexation of the three Baltic countries – Estonia, Latvia, and Lithuania – in conformity with the principles of the Stimson Doctrine, and more than 50 countries followed this position.
The Republic of Estonia, from 1940 through 1991, continued to exist as a state de jure according to international law during the whole period of its actual occupation and annexation. Therefore, some Estonian diplomatic and consular representations continued to function from 1940 through 1991 in some Western countries, dealing with a limited part of state functions of the Republic of Estonia.
