In May 1987, the Lithuanian Cultural Fund was established to engage in environmental activity and the protection of Lithuanian cultural assets. On 3 June 1988, the Lithuanian Reformation Movement (LRM) was founded; its mission was to restore the statehood of Lithuania; LRM supporters formed groups across Lithuania. On 23 August 1988, a meeting took place at Vingis Park in Vilnius, with a turnout of about 250,000 people. On 23 August 1989, marking 50 years of the Molotov–Ribbentrop pact and aiming to draw the world's attention to the occupation of the Baltic states, the Baltic Way event was staged. Organised by the Lithuanian Reformation Movement, the Baltic Way was a chain of people holding hands that stretched for nearly to connect the three Baltic capitals of Vilnius, Riga, and Tallinn. It was a display of the aspiration of the Lithuanian, Latvian, and Estonian people to part ways with the USSR. The LSSR "de facto" ceased to exist on 11 March 1990, with the Reconstituent Seimas declaring Lithuania's independence restored. Since Lithuania's membership in the USSR was considered a violation of the international law and void, there was no formal procedure of secession from the USSR.
