There were several reasons why people feared a rise in radicalism after World War I ended. One factor was the arrival of communism in the Soviet Union. The people who supported the communist system, which is very different from the American political system of democracy and the economic system of capitalism, wanted to spread communism throughout the world. Many Americans believed that the Soviet Union was trying to bring communism to the United States. This was known as the Red Scare and had many people worried that radical ideas were gaining a foothold in the country.

Another concern was the growing number of immigrants coming to the United States from countries in south and Eastern Europe. These immigrants, some of whom were anarchists, had very different customs, languages, and ways of living than the Americans who had come to the United States from countries in north and Western Europe. Americans were frightened by these people's differences and wanted to limit their access to the United States. Many Americans feared that anarchists were connected to the spread of communism.

There were also economic issues after World War I ended. Inflation became a big issue, and many workers went on strike. These strikes, in some people’s minds, added credence to the idea that the communists were trying to spread their ideas to the United States. In some ways, it was easier to blame the communists than to deal with the economic issues that existed in our country.

The fear of radicalism that happened after WWI is typically known as the "red scare" or sometimes the "first red scare."  During this time, Americans were worried about the growth in radical ideas, especially among immigrants and workers.  There were three main causes of this fear.

First, there was the fact that Russia had become communist and was overtly talking about spreading its revolution abroad.  This made Americans fear that their country would be a target for communists.

Second, there was the large influx of immigrants, some of whom were radical, in the late 1800s and early 1900s.  Americans felt that there were large numbers of radicals among the immigrants and that American ideals were in danger.

Finally, there were major strikes in many US cities in 1919.  These strikes helped to convince many Americans that the labor movement was filled with these radical immigrants who were going to topple the US system.

For these reasons, a fear of radicalism arose in the US after WWI.
