Nigeria's first participation in a United Nations peace-keeping operation was in Congo. In 1960, the UN sent a peacekeeping force to Congo to maintain order and assist with the country's transition to independence. Nigeria was among the first African countries to send troops to this operation, and they played a significant role in helping to restore peace to the troubled region. This was a significant moment in Nigeria's history, as it marked the beginning of the country's long and ongoing involvement in peacekeeping operations around the world.
