Final answer:
The renaming of sauerkraut to "liberty cabbage" during World War I is an example of anti-German propaganda.
Step-by-step explanation:
The renaming of sauerkraut to "liberty cabbage" during World War I is an example of anti-German propaganda. The U.S. government sponsored propaganda campaigns to create an anti-German sentiment among the American public. They wanted to ensure that American immigrants who sympathized with Germany would not hinder the U.S. war effort. This renaming was part of a larger effort to stigmatize German culture and discourage support for Germany.
