The 30th anniversary of the petition that gave a voice to opposition in Czechoslovakia.The Czech centre and Orange Tree Theatre present an evening to celebrate the 30th anniversary of the petition that started a movement representing the leading platform for opposition in Czechoslovakia under the Communist regime. After an adventurous start in January 1977, the petition called Charter 77 gained international support and many events were held internationally to draw attention to the chartists and their call for freedom of speech and expression and respect for human rights. Some of those who were personally involved in the movement and helped to gain international support and to draw attention to the petition will gather together to share their experience and memories of one of the most significant events in Modern European history. Discussion chaired by Timothy Garton Ash. Introduction by Sam Walters.
