blishment of Sąjūdis, an anti-communist independence movement. After a landslide victory in elections to the Supreme Soviet, members of Sąjūdis proclaimed Lithuania's independence on 11 March 1990, becoming the first Soviet republic to do so. The Soviet Union attempted to suppress the secession by imposing an economic blockade. Soviet troops attacked the Vilnius TV Tower, killing 14 Lithuanian civilians and wounding 600 others on the night of 13 January 1991 (January Events). On 31 July 1991 Soviet paramilitaries killed seven Lithuanian border guards on the Belarusian border in what became known as the Medininkai Massacre.
On 4 February 1991, Iceland became the first country to recognise Lithuanian independence. After the Soviet August Coup, independent Lithuania received wide official recognition and joined the United Nations on 17 September 1991. The last Soviet troops left Lithuania on 31 August 1993 – even earlier than they departed from East Germany. Lithuania, seeking closer ties with the West, applied for NATO membership in 1994. After a transition from a planned economy to a free market one, Lithuania became a full member of NATO and the European Union in the spring of 2004 and a member of the Schengen Agreement on 21 December 2007
