How are the 'Baltic Way' and 'The Singing Revolution' connected?

The "Baltic Way" and "The Singing Revolution" are closely linked as key events in the peaceful independence movements of the Baltic states - Estonia, Latvia and Lithuania - from Soviet rule.

The Singing Revolution refers to a series of non-violent protests between 1987 and 1991 in which large crowds gathered in the Baltic states to sing national songs and hymns, which had been banned under Soviet rule. This act of cultural resistance was instrumental in building national unity and expressing the desire for independence.

The Baltic Way, which took place on 23 August 1989, was a powerful manifestation of the Singing Revolution. Around two million people formed a human chain over 600 kilometres long, linking the capitals of Vilnius (Lithuania), Riga (Latvia) and Tallinn (Estonia). The date was chosen to mark the 50th anniversary of the Molotov-Ribbentrop Pact, which led to the Soviet occupation of the Baltic states.
