In this video segment, from the PBS documentary Looking for Lincoln<span>, Henry Louis Gates, Jr. and historian David Blight examine President Abraham Lincoln’s mixed motivations for issuing the Emancipation Proclamation. They conclude that while Lincoln ultimately recognized the moral righteousness freeing the slaves, his first and primary concern was strategic: it was the best way to rally the North and strike at the heart of the South’s economy. Gates and Blight then join a roundtable discussion of Lincoln scholars debating the legal authority of the Proclamation and its special meaning for African Americans.</span>

Answer:
<h2>The Red Scare</h2><h3>(technically, the First Red Scare)</h3>
Explanation:
What historians refer to as the first Red Scare occurred from 1919 to the early 1920s in the United States, following the Bolsvhevik Revolution which brought communism to power in Russia. The Bolsheviks (meaning "the Majority") were the communist faction that led a successful overthrow of the regime of the tsar in Russia in 1917. They weren't a "majority" in Russia, but they were the dominant group within the Russian communist movement. Civil war in Russia followed during the next years, from 1917 into the early 1920s, ultimately leading to the establishment of the Union of Soviet Socialist Republics (USSR) in 1922. There was fear in the United States (as there was elsewhere in the world) that communism would begin to spread further, beyond Russia. Attorney General Mitchell Palmer used that fear as an excuse to arrest suspected radicals in the United States.
The more common reference to "The Red Scare" usually refers to what historically was the second Red Scare, from the late 1940s to late 1950s in the United States. Following World War 2, as the Cold War developed and the Soviet Union was gathering allies, there was even greater fear -- and fear-mongering -- in the United States about the threat of communism. The Second Red Scare was when The House Un-American Activities Committee (HUAC) was created and when Senator Joseph McCarthy began a campaign of accusations against suspected communists in various sectors of American life.
