The first red scare was a period of hysteria based around communism and the security of democracy and capitalism in America. People with large sums of money were especially scared of communism because of the concept of the redistribution of wealth.
(There are no people because they were all scared)
the red scare was a direct response to the Bolshevik revolution in Russia that led to the establishment of a communist government. Many pro-Bolshevik demonstrations took place across the U.S. This was seen as a threat to security by many political leaders and wealthy business owners.
The red scare led to the discrimination of many different groups of people for their either pro-socialist or anti-government views. Assumptions were made about people based off their country of origin or of people close to them.
Due to the atheist nature of the Bolshevik revolution, communism was seen as a threat to the catholic church in America. Religious persons in America took a large opposition to communism, and sought to halter its spread and protect their own personal interests.
The socialist party during the red scare received plenty of backlash from wealthy businessmen. Although the idea of communism grew greater among the working class, most serious attempts at revolution were quickly found out and crushed.
The red scare is significant in U.S. history because it is a precursor to McCarthyism and the cold war that would take place later in the 20th century. Plenty of the red scare included the conviction of many politicians and other progressives whose ideas were seen as too dangerous to democracy. The fear of communism fueled the American ideals, such as freedom and democracy. The red scare resembles the 20's because it was the era that relied on surrealism and impressionism, and plenty of people took their own subjective ideas on new ideas and related them to communism.
