Cross-Topic Links
- → Topic 3 (America in 1920): WASP fear of rapid change was already visible in 1920 — the 11 million "new immigrants" of 1900-1920, the growing cities, and the shifting social order created the anxieties that erupted into KKK revivals and the Red Scare in the 1920s.
- → Topic 8 (Prohibition): Prohibition and intolerance share the same root — rural Protestant WASPs using law and violence to resist the urban, immigrant, Catholic, and "modern" culture that threatened their dominance; both are sides of the same conservative reaction.
- → Topic 4 (Economic Boom): The prosperity that benefited white urban Americans first made inequality more visible — those left out (immigrants, Black Americans, rural poor) were the same groups targeted by intolerance, showing how economic exclusion and social prejudice reinforced each other.
- → Topic 16 (Segregation): The KKK's racial violence against Black Americans in the 1920s is part of the same system of legal and extra-legal oppression (Jim Crow + mob violence) that made formal segregation possible and required decades of organised resistance to dismantle.
- → Topic 15 (WW2 and Post-War): McCarthyism (1950-54) was a direct descendant of the 1920s Red Scare — both exploited fear of communism and used accusations without evidence to destroy people; understanding the 1920s pattern helps explain how post-war anti-communist hysteria took the same form.
