Why did the French Revolution loose American support?

The French Revolution lost some U.S. support when French citizens migrated to the United States to escape their war-torn country. Many refugees started their own newspapers and propaganda campaigns, encouraging Americans to support their radical ideas and political agendas.

the historians cited in the article all agree with one another about the cause of the civil war. despite coming from different backgrounds and cultures, the historians agree that slavery was the root cause of the civil war. the fact that all these historiansgenerally agree with one another makes their shared viewpoints more reliable and valid, especially because the historians have different backgrounds and all work for the well-respected institutions of howard university, clemson university, and the university of colorado.
