The Great Shift: From Welcome Mat to Closed Doors

America's immigration story took a dramatic turn in the 1920s. The country had originally aimed to be a 'melting pot' where different nationalities would blend into one American identity, though many immigrants actually preferred staying in their own communities (creating more of a 'salad bowl' effect).

WASP society (White Anglo-Saxon Protestants) began feeling threatened by the wave of new immigrants from Eastern Europe who brought different religions - mainly Catholic and Jewish faiths. This religious divide became a major flashpoint that changed everything.

The most visible and violent result of this prejudice was the revival of the Ku Klux Klan. By the mid-1920s, they had several million members and weren't just targeting Black Americans - they went after anyone who didn't fit their WASP ideals. Their crimes included hangings, mutilations, and kidnappings.

Key Point: The film 'Birth of a Nation' actually portrayed the KKK as heroes saving America from 'Un-American' ideas, showing how mainstream these prejudiced views had become.

The Red Scare: When Fear Drove Policy

The Russian Revolution of 1917 sent shockwaves through America. Since many immigrants came from Russia and Eastern Europe, Americans became paranoid about communist revolution spreading to their shores - this panic was called the 'Red Scare'.

Things got real when General Palmer's home was bombed and letter bombs were sent to government officials. Suddenly, every immigrant looked like a potential revolutionary. The country was gripped by what historian Alistair Cooke described as fear that "the last great wave of immigrants had brought the revolutionary spirit with them."

However, this fear proved largely unfounded. By 1920, General Palmer had arrested 4,000 alleged communists, but no actual revolution materialised. Once people realised there was no real threat, the Red Scare's influence on immigration attitudes began to fade.

Social fears also played a role, with politicians blaming immigrants for rising crime rates. The Italian Mafia became a newspaper target, and Al Capone's high-profile criminal activities seemed to 'prove' that immigrants brought crime with them.

Reality Check: The infamous Sacco and Vanzetti case $1920-1927$ showed how prejudice could override justice - many believed these two Italian immigrants were executed more for their radical political views than for the murders they were accused of.

The Bigger Picture: Why This Matters

World War I added another layer of complexity, as anti-German propaganda increased tensions between German immigrants and other Americans, even though the US had relied on immigrant labour during the war.

Economic fears grew as housing shortages hit cities like New York. WASPs made it nearly impossible for immigrants to find housing, and the idea that immigrants were 'stealing jobs' gained popularity among American workers.

The government's response was swift and decisive. The 1921 Emergency Quota Act specifically limited immigrants from Eastern and Southern Europe whilst still allowing WASPs to enter freely. This wasn't about numbers - it was about excluding 'undesirable' groups.

Prejudice and racism emerged as the most significant factor because it fueled all the others. Without the underlying religious and ethnic prejudices, groups like the KKK wouldn't have gained millions of members, and the fears about revolution and crime might not have taken such deep root in American society.

Bottom Line: The 1920s immigration restrictions weren't just about economics or security - they were fundamentally about preserving WASP dominance in American society, showing how prejudice can shape entire national policies.
