The Inter-American Convention on the Prevention, Punishment, and Eradication of Violence against Women, also known as the Convention of Belem do Para, is the first legally binding international human rights instrument to specifically address violence against women. Drafted and adopted by the Organisation of American States (OAS), it called for the established of mechanisms in the Americas for the protection of women against violence in both the private and public spheres. Most importantly, it has been a major trigger for significant legislative and policy reform in all of the signatory countries. To date, it has been ratified by 32 of the 35 states of the OAS. The USA, Canada, and Cuba have not signed on to the Convention.
