Milloin Neuvostoliitto tunnusti Viron itsenäisyyden?
On 16 November 1988, the Estonian SSR became the first republic within the Soviet sphere of influence to declare state sovereignty from Moscow. On 30 March 1990, the Estonian SSR declared that Estonia had been occupied since 1940 and declared a transitional period for the country's full independence. The Estonian Soviet Socialist Republic was renamed as the Republic of Estonia on 8 May 1990. The independence of the Republic of Estonia was re-established on 20 August during the 1991 Soviet coup d'état attempt the following year and the Soviet Union itself recognised the independence of Estonia on 6 September 1991.
