the Red Scare refers to a period of political and cultural instability in the United States during the late 1940s and the 1950s wherein the United States was so fearful of communists in their midst due to a Cold War with the United States that neighbors informed on neighbors and people were blacklisted from employment.
Through the Black Codes, blacks were not allowed to testify against whites, serve on juries or to vote. Blacks who did not sign yearly labor contracts with planters could be arrested. Some states limited job opportunities, barred them from acquiring land and even allowed judges to assign black children to work for their former owners without their parents consent.
It allowed Missouri and then Maine (which also applied for statehood) to become states. A lot of states were on the edge on wether to admit or not allow a state that allows slavery into the states. In the end - both were admitted and became states. However, Missouri was left as a slave state and Maine was set as a free state.
