The origins of this day go back to the beginning of the 20th century, when women from all over the world united to defend their rights and demand the right to vote.
An international day of action has been proposed since 1917.
8 March 2000 was marked by the European launch of the World March of Women in Geneva.
This date marks the anniversary of the adoption by the Swiss people of the constitutional article on equality between women and men (in 1981).
Ten years later, during the women's strike, almost half a million women rallied to express their indignation at the failure to comply with this text.
Despite the introduction of the Equality Act in 1996, there is still a long way to go.
