The revolution in Russia is one of the many events that helped to make for uncertain times at the start of the First Red Scare.

Explanation:

The First Red Scare is the name used to designate a relatively short period in the history of the United States immediately after World War I, when parts of the society as well as the authorities were convinced that danger was coming from the Bolsheviks. Such an impression has created a series of incidents, from strikes through racial unrest and terrorist attacks, interpreted as part of a plan to prepare for a revolution similar to the recent October Revolution in Russia. They were reflected through a series of repressive measures aimed at preventing communist activity, with leftists being the most prominent victims, most often of foreign origin, many of whom as anarchists and social democrats had no direct connection with communism. Of these, the most famous are the so-called Palmer raids carried out in late 1919 and 1920. Contemporaries eventually began to criticize these measures as exaggerated, and by the late 1920s the mood began to increase as the danger of the Bolshevik revolution was exaggerated. Many historians, however, consider the First Red Scare to serve as a model for the later anti-Communist campaign after World War II.
