The term was coined by an Estonian activist and artist, Heinz Valk, in an article published a week after 10–11 June 1988, spontaneous mass evening singing demonstrations at the Tallinn Song Festival Grounds. Later, all three countries joined EU and NATO in 2004.

An independence referendum was held in the Latvian SSR on 3 March 1991, alongside a similar referendum in the Estonian SSR the same day.

The act emphasized restoration and legal continuity of the interwar-period Lithuania, which was occupied by the Soviet Union and lost independence in June 1940. It was the first Soviet republic to declare independence from the Soviet Union that would cause the dissolution of the Soviet Union in 1991.

The Declaration "On the Restoration of Independence of the Republic of Latvia" was adopted on 4 May 1990, by the Supreme Soviet of the Latvian SSR. The Declaration stated that, although Latvia had de facto lost its independence in 1940, when it was annexed by the Soviet Union, the country had de jure remained a sovereign country as the annexation had been unconstitutional and against the will of the Latvian people. Therefore, it resolved that the Molotov–Ribbentrop Pact and the Soviet occupation of Latvia in 1940 were illegal. It also asserted that the heavily rigged 1940 elections were illegal and unconstitutional, and that all acts of the "People's Saeima" chosen at that election–including the request to join the Soviet Union on 21 July 1940–were ipso facto void.

The Popular Front of Estonia, introduced to the public by the Estonian politician Edgar Savisaar under the short-lived name Popular Front for the Support of Perestroika, was a political organisation in Estonia in the late 1980s and early 1990s. Edgar Savisaar introduced the idea of popular front during a TV show on 13 April 1988.

Roko maršas was a rock music festival, organized in various cities of Lithuania. It was held in 1987–1989. It was resurrected in 1996 and 1997. The first festivals were organized while Lithuania was still part of the Soviet Union. They became part of the Singing Revolution, spreading ideas of the Lithuanian independence movement among the youth. It helped to awaken the younger generation from Soviet-era apathy and inspire them. In total, the three first festivals attracted an estimated 130,000 spectators. The festivals became a rehearsal for the mass protest rallies by the Sąjūdis that lead to the declaration of Lithuania's independence in March 1990.

The revolutionary songs they created anchored Estonia’s non-violent struggle for freedom.

The Soviet economic blockade of Lithuania was the economic blockade imposed by the Soviet Union on Lithuania between 18 April and 29 June 1990. It began soon after Lithuania declared restoration of its independence on 11 March 1990. The Soviets hoped that the economic difficulties would force the Lithuanian leadership to revoke or suspend the independence restoration. Even though Lithuania entered into negotiations to end the blockade, the Soviet Union did not regain control of the country, later resorting to military means in an attempt to stop the independence process.

The Barricades were a series of confrontations between the Republic of Latvia and the Union of Soviet Socialist Republics in January 1991 which took place mainly in Riga. The events are named for the popular effort of building and protecting barricades from 13 January until about 27 January. Latvia, which had declared restoration of independence from the Soviet Union a year earlier, anticipated that the Soviet Union might attempt to regain control over the country by force.
