Answer:
1. African Americans are granted official citizenship of the United States
2. African Americans are granted the right to vote
3. 265 African Americans delegates were elected (100 of them were ex-slaves)
4. 16 African Americans served in the United States Congress
Step-by-step explanation:
During the decade known as Radical Reconstruction (1867-77), Congress granted African American men the status and rights of citizenship, including the right to vote, as guaranteed by the 14th and 15th Amendments to the U.S. Constitution. Beginning in 1867, branches of the Union League, which encouraged the political activism of African Americans, spread throughout the South. During the state constitutional conventions held in 1867-69, Black and white Americans stood side by side for the first time in political life.
Black citizens made up the overwhelming majority of southern Republican voters, forming a coalition with “carpetbaggers” and “scalawags” (derogatory terms referring to recent arrivals from the North and southern white Republicans, respectively). A total of 265 African-American delegates were elected, more than 100 of whom had been born into slavery. Almost half of the elected Black delegates served in South Carolina and Louisiana, where Black people had the longest history of political organization; in most other states, African Americans were underrepresented compared to their population. In all, 16 African Americans served in the U.S. Congress during Reconstruction; more than 600 more were elected to the state legislatures, and hundreds more held local offices across the South.
