… on 23 August 1989, the three nations living by the Baltic Sea surprised the world by taking hold of each other’s hands and jointly demanding recognition of the secret clauses in the Molotov-Ribbentrop pact and the re-establishment of the independence of the Baltic States. More than a million people joined hands to create a 600 km long human chain from the foot of Toompea in Tallinn to the foot of the Gediminas Tower in Vilnius, crossing Riga and the River Daugava on its way, creating a synergy in the drive for freedom that united the three countries.
