Answer:
The National Equal Rights League was founded by African Americans. It was established in 1864 by a group of prominent African American activists and leaders, including Frederick Douglass. The organization aimed to advocate for equal rights for African Americans, particularly in the areas of suffrage, education, and civil rights. The National Equal Rights League played a crucial role in pushing for the ratification of the 14th and 15th Amendments to the United States Constitution, which granted citizenship and voting rights to African Americans. It is important to note that while the Republican Congress supported civil rights legislation during this time, the National Equal Rights League was founded specifically by African Americans themselves.
