The coming of World War I brought with it a backlash against German culture in the United States. When the U.S. declared war on Germany in 1917, anti-German sentiment rose across the nation, and German American institutions came under attack. Some discrimination was hateful, but cosmetic: The names of schools, foods, streets, and towns, were often changed, and music written by Wagner and Mendelssohn was removed from concert programs and even weddings. Physical attacks, though rare, were more violent: German American businesses and homes were vandalized, and German Americans accused of being "pro-German" were tarred and feathered, and, in at least once instance, lynched.
