OCSE

In English: The Organisation for Security and Co-operation in Europe (OSCE)
In Polish: Organizacja Bezpieczeństwa i Współpracy w Europie OBWE
OCSE is an operational international organisation, which serves as a major forum for political dialogue and aims to secure stability in the region, based on democratic practices and good governance.
The Organisation was established in 1973 as the Conference on Security and Co-operation in Europe (CSCE). Talks had been mooted about a European security grouping since the 1950s but the Cold War prevented any substantial progress until the talks at Finlandia Hall in Helsinki began in November 1972. These talks were held at the suggestion of the Soviet Union which wished to use the talks to maintain its control over the communist countries in Eastern Europe. Western Europe, however, saw these talks as a way to reduce the tension in the region, furthering economic co-operation and obtaining humanitarian improvements for the populations of the Communist bloc.
