What this topic is asking
The same decade that "roared" with modern culture also seethed with conflict between old and new ways of life. Standard 4 (Becoming a World Power through World War II) wants you to analyze the cultural conflicts of the 1920s: Prohibition, nativism and immigration restriction, the revived Ku Klux Klan, and the clash between fundamentalism and modern science. LEAP often uses a Prohibition photograph, a quota-law chart, or a Scopes Trial excerpt as the source.
Prohibition and its failure
Nativism and immigration restriction
The fear of foreigners that had surged during the war and the Red Scare hardened into law.
Congress passed immigration quota laws in the early 1920s that sharply reduced immigration and set quotas based on national origin. The quotas deliberately favored immigrants from northern and western Europe and restricted those from southern and eastern Europe, while barring most Asian immigration almost entirely. The goal was nativist: to preserve the older ethnic makeup of the country by keeping out "new" immigrants seen as harder to assimilate. These laws ended the era of large-scale open immigration that had built industrial America.
The revived Ku Klux Klan
The Ku Klux Klan, dormant since Reconstruction, was revived in the 1910s and grew explosively in the 1920s, reaching millions of members and spreading well beyond the South. The new Klan still targeted African Americans but now also attacked immigrants, Catholics, and Jews, presenting itself as the defender of "old-stock" white Protestant America. Its power faded later in the decade amid scandal and corruption, but its rise shows how widespread the backlash against change had become.
Fundamentalism and modern science
The decade also pitted traditional religion against modern science.
A divided decade
The exam reward is recognizing the tension at the heart of the 1920s. The same years brought the modern consumer culture and the cultural backlash, the flapper and the Klan, jazz and Prohibition. The "Roaring Twenties" was not simply a carefree boom; it was a society arguing fiercely over what it should become.

A single-select item assessing analysis of a source (Standard 4; Standard 1 source analysis).
Correct answer: Prohibition, the nationwide ban on the manufacture and sale of alcohol under the Eighteenth Amendment.
Banning alcohol did not stop demand; it created a black market of speakeasies and bootleggers and fueled organized crime, which is why Prohibition is seen as a failed experiment. Distractors such as "the repeal of Prohibition" reverse the cause, since repeal came later in 1933.
LA LEAP 2025 US History (style)2 marksPart A: What was the purpose of the immigration quota laws of the 1920s? Part B: How did these laws reflect the nativism of the decade?Show worked answer →
A two-part evidence-based item (Standard 4; Standard 1 claims and evidence).
Part A (1 point): the immigration quota laws sharply limited immigration and set quotas favoring immigrants from northern and western Europe while restricting those from southern and eastern Europe and barring most Asians.
Part B (1 point): the laws reflected nativism because they were designed to preserve an older ethnic makeup of the country by favoring "old" immigrant groups and shutting out "new" immigrants seen as less desirable. A distractor saying the laws welcomed all immigrants equally contradicts the discriminatory quotas.
Markers reward describing the quota system in Part A and linking it to nativist motives in Part B.
