What organization, founded by Booker T. Washington, aimed to support African American businesses with numerous chapters across the country?

The National Negro Business League, founded by Booker T. Washington in 1900, was specifically established to promote and support African American entrepreneurship. Washington believed that economic independence was crucial for the advancement of African Americans and that business ownership could help secure social and political rights. The league aimed to provide a platform for Black business owners and foster economic development in African American communities by organizing chapters across the country, offering resources, and facilitating networking opportunities.

The other organizations listed focus on different aspects of civil rights and education. The National Association for the Advancement of Colored People (NAACP), for example, was primarily focused on civil rights and combating racial discrimination. The Black Business Alliance and the United Negro College Fund (UNCF) also play significant roles in supporting African American interests, but they do not have the same historical connection to Booker T. Washington's vision of promoting business as the National Negro Business League.
