Radical Reconstruction began in response to the lenient policies of Andrew Johnson

In 1867, Congress passed the Reconstruction Acts—overriding Johnson's vetoes—placing the South under military rule and requiring new state constitutions, Black male suffrage, and ratification of the 14th Amendment before readmission.

The end of Reconstruction paved the way for Jim Crow segregation

The 15th Amendment granted Black men the right to vote nationwide

Ratified in 1870, the 15th Amendment prohibited federal and state governments from denying the right to vote based on race, color, or previous condition of servitude—enfranchising millions of Black men.

The Dred Scott decision denied citizenship to people of African descent

How did segregation in the US affect blood donations?

When the US established its first nationwide network of blood banks in 1941 with the hopes of restoring the dwindling reserves of military members, it was quick to emphasize blood donated by Black Americans wouldn't coat the veins of white servicemen. Historians say this policy was meant to appease white Southerners who believed Black blood was inferior to their own.This policy was leaked to the press that same year.
