Final answer:
Anti-German Hysteria during World War I led to increased discrimination against German-Americans, intense propaganda campaigns, and the suppression of German culture and language.
Step-by-step explanation:
The impact of Anti-German Hysteria during World War I was multifaceted and included: increased discrimination against German-Americans, extensive propaganda campaigns against Germany, and restrictions on German culture and language. This resulted in acts such as persecution of German Americans, shunning of their businesses, withdrawal of German-language books from libraries, and renaming of streets and buildings to remove German associations. Additionally, the hysteria fueled censorship and suppression of views that were deemed unpatriotic or dissenting. Internment camps were established for some residents suspected of sympathizing with enemy powers, and businesses and individuals were pressured into disclosing any 'un-American' activities or comments observed in their communities.
