Organization for Security and Co-operation in Europe
in November 1972, leaders of 35 countries met in Helsinki. In 1973, these countries set up the Conference for Security and Co-operation in Europe (CSCE). By the end of 1990s, communist governments in many countries had changed. In this situation, the role of CSCE was also changing. The leaders from member countries of CSCE met in Paris. On 21st November 1990, they signed an agreement. This changed the name of Conference for Security and Co-operation in Europe (CSCE) to Organization for Security and Co-operation in Europe (OSCE). This international organization continues to function.
