In response to the establishment of Charter 77 and the campaign against its signatories, the first major conference on Charter 77 and respect for human rights in Czechoslovakia was held at the Dauphine University in Paris on January 14^th, 1977. The conference was led by Pierre Emmanuel, a member of the French Academy, and Vladimir Bukovsky was also present. Directly at the conference, The International committee for the support of principles of the Charter 77 in Czechoslovakia was established at the initiative of Ivana and Pavel Tigrid, member of the French Academy of Pierre Emmanuel, secretary of the Socialist Party of Gillese Martinet and former editor of the Communist Party of France writer Pierre Daix. Membership of the Committee has received over thirty leading political and cultural figures in Western Europe and the United States, including the internationally renowned writers Heinrich Böll, Günter Grass, Arthur Miller, and Friedrich Dürrenmatt. Among the members of the Committee were three Nobel laureates, as well as well-known French actors Yves Montand and Simone Signoret. Ivana Tigridová, who was elected as the Committee's honorary secretary, eventually resigned from this position, as because of her name, she did not want to compromise the work of the International Committee.

The International Committee for the promotion of Charter 77 focused its efforts on supporting the signatories of Charter 77 in their efforts to implement human and civil rights in the country. They held a series of protest events; one of the largest Czechoslovak campaigns that took place in the West was a campaign in 1979 against the prosecution of members of the Committee for the Defence of Unjustly Prosecuted Persons.

The work of the International Committee to Support Charter 77 ended in the fall of the Iron Curtain, which meant the defeat of totalitarian regimes in the Soviet bloc countries.
