Taking into account the statement above: "World War I and the importance placed on nationalism in politics created a backlash against ethnic and racial differences in the United States. Identify the examples of ""Americanization"" that took place in the country."
The answer is: well, the federal and the state governments demanded that the immigrants demonstrate their unwavering devotion to the United States.
Also, the public schools paid special attention to the children of immigrants in attempt to teach them American values.
Hope this helps.
