by Carlton J. H. (Carlton Joseph Huntley) Hayes
Born in 1882, Carlton J. H. Hayes was an American historian, educator, and public servant best known for his work on nationalism and modern European history. He taught at Columbia University and became one of the prominent U.S. scholars interpreting the political and cultural forces that shaped Europe in the modern age.
Hayes wrote widely on the French Revolution, contemporary Europe, and the history of nationalism. He is often noted for treating nationalism as a powerful modern belief system rather than just a political program, an approach that gave his historical writing lasting influence.
During World War II, he served as the United States ambassador to Spain from 1942 to 1945. He died in 1964, leaving behind a body of work that bridged academic history and public affairs.
