Helsinki Accords, also called Helsinki Final Act, (August 1, 1975), major diplomatic agreement signed in Helsinki, Finland, at the conclusion of the first Conference on Security and Co-operation in Europe (CSCE; now called the Organization for Security and Co-operation in Europe). The Helsinki Accords were primarily an effort to reduce tension between the Soviet and Western blocs by securing their common acceptance of the post-World War II status quo in Europe. The accords were signed by all the countries of Europe (except Albania, which became a signatory in September 1991) and by the United States and Canada. The agreement recognized the inviolability of the post-World War II frontiers in Europe and pledged the 35 signatory nations to respect human rights and fundamental freedoms and to cooperate in economic, scientific, humanitarian, and other areas. The Helsinki Accords are nonbinding and do not have treaty status.
