Charter 77 – a manifesto written by Vaclav Havel to call attention to human rights violations within Hungary. It used the Helsinki Acts against the repressive measure of the Hungarian government, reminding the government that, as a signatory, it had agreed to respect the civil, social and cultural respects of its people. Initially, there were 243 signatories, and Havel sent it to Deutsche Welle radio and West German television, knowing this would make it known in East Germany.
