Four world conferences on Women have been organized by the UN. These conferences have taken place in Mexico City in 1975; Copenhagen in 1980; Nairobi in 1985; and Beijing in 1995.
The 1995 Fourth World Conference on Women in Beijing was a turning point for the global women’s movement. Over 17,000 participants attended, including 6,000 government delegates, 4,000 accredited NGO representatives, many international civil servants and about 4,000 media representatives. A parallel NGO Forum took place near Beijing in Huairou, which gathered over 30,000 people. The outcome of the conference, the Beijing Declaration and the Platform for Action, was adopted unanimously by 189 countries. This agenda, according to UN Women, is considered "the most progressive blueprint ever for advancing women’s rights" and "the key global policy document on gender equality".
2020 marks the 25th anniversary of the Beijing Declaration and Platform for Action (BPfA). In 2020, UN Women and the Commission on the Status of Women will undertake a review and analysis of the implementation of the BPfA and the outcomes of the twenty-third special session of the General Assembly. It has called for national and regional-level reviews, the outcomes of which will feed into the 2020 review to be undertaken by the Commission.
