The Universal Negro Improvement Association (UNIA) was a Black nationalist organization founded by Marcus Garvey in 1914. The UNIA was one of the most influential Black movements of the early 20th century, aiming to promote unity and empowerment among people of African descent worldwide.

Under Garvey's leadership, the UNIA advocated for Black economic self-sufficiency, racial pride, and the repatriation of African Americans to Africa. The organization also established businesses, schools, and other institutions to support the Black community.

One of the UNIA's most significant achievements was the "Back to Africa" movement, which inspired thousands of African Americans to embrace their African heritage and consider resettling in Liberia or other parts of Africa.

The UNIA's message of Black empowerment and pride resonated with many African Americans and people of African descent around the world, making it a powerful force in the fight for civil rights and racial equality.
