As the U.S. entered World War I, German culture was erased as the government promoted the unpopular war through anti-German propaganda. This backlash culminated in the lynching of a German immigrant.
German-Americans are America’s largest single ethnic group (if you divide Hispanics into Mexican-Americans, Cuban-Americans, etc). Yet despite their numbers, they are barely visible. During the first world war, parts of America grew incredibly anti-German. Many stopped speaking German and anglicized their names. “In 1915 about 25% of all high school students in America studied German, but by the end of the World War I German had become so stigmatized that only 1 percent of high schools even taught it.”
