The United Nations (UN) has played a significant role in Black history with its mission to promote peace, security, and human rights across the globe. Black individuals and nations have been part of the UN's history since its inception in 1945.

One of the milestones in Black history within the UN is the recognition of African decolonization and independence movements. The UN played a crucial role in supporting African nations in their struggles for independence from colonial rule. For example, the UN Special Committee on Decolonization worked to assist colonized nations in achieving self-governance and independence, leading to the eventual decolonization of many African countries.

Furthermore, the UN has played a key role in addressing racial discrimination and promoting equal rights for Black people around the world. The International Convention on the Elimination of All Forms of Racial Discrimination, adopted by the UN General Assembly in 1965, is a crucial human rights treaty that aims to combat racism and promote racial equality. The UN also established the International Decade for People of African Descent (2015-2024) to focus on addressing the challenges faced by people of African descent globally.

Additionally, Black individuals have made significant contributions to the work of the UN. For example, Ralph Bunche, an African American diplomat and political scientist, was the first person of color to receive the Nobel Peace Prize for his mediation efforts in the Israeli-Arab conflict through the UN. Kofi Annan, a Ghanaian diplomat, served as the Secretary-General of the UN from 1997 to 2006, becoming the first person from sub-Saharan Africa to hold that position.

Overall, the UN has been a platform for Black voices and a vehicle for promoting equality, justice, and empowerment for people of African descent around the world.
