Solution:The African Charter on Human and People's Rights, commonly known as the Banjul Charter, was formally adopted by the Assembly of Heads of State and Government of the Organisation of African Unity (OAU) in Nairobi, Kenya, on 27 June 1981.
Although the drafting and finalisation of the text took place earlier in Banjul, Gambia, the official adoption occurred during the OAU's 18th Summit in Nairobi, where all member states unanimously approved the Charter.
The Charter is distinctive for recognising both individual and collective ("peoples'") rights, reflecting African traditions and socio-political contexts. It entered into force on 21 October 1986, marking a significant milestone in Africa's regional human rights framework.
