The African Charter on Human and Peoples’ Rights, also known as the Banjul Charter on Human and Peoples’ Rights, was adopted by the 18th Assembly of Heads of State and Government of the Organization of African Unity (OAU), held in Nairobi in June 1981. Contrary to some expectations, the Charter stayed in limbo for only 5 years. It entered into force on October 21, 1986, after the deposit of the 26th instrument of ratification, the number required by its Article 63(3). By April 16, 1987, there were 33 states parties to the Charter, which makes it the largest regional human rights system in existence.
