Final answer:
Frederick Douglass was the African American leader who rejected emigration and instead appealed to political methods to end slavery and gain citizenship.

Washington, pursued further political and educational rights for Black people.
Step-by-step explanation:
The African American leader who rejected emigration and instead explored political methods to end slavery and gain citizenship was Frederick Douglass. A fervent abolitionist, Douglass channeled his efforts towards incorporating people from around the globe into what he termed a 'composite nation'. He considered America's diversity as a key element in its success. Douglass campaigned against discrimination faced by various races, including Chinese immigrants, exemplifying his belief in equal rights for all.
Unlike President Johnson, who rejected the Fourteenth Amendment and believed that ending slavery was enough, Douglass and other civil rights advocates like W.E.B. Du Bois and Booker T. Washington pursued further political and educational advancements for Black citizens. They aimed for a society where Black people could enjoy full citizenship rights, leading the fight against discrimination and striving for social justice.
