Successes and failures

Successes: peacekeeping missions, eradication of smallpox (WHO), decolonisation support, humanitarian aid. Failures: inability to prevent some conflicts and genocides (Rwanda in 1994), the veto blocking action, and dependence on members' funding.

Regional organisations

The OAU (1963) and its successor the African Union (2002); SADC (1992, formerly SADCC formed in 1980).
