Why were Italians called dagos?

Answer 1

The term "dago" is a derogatory slang used primarily in the United States to refer to Italians and, at times, Spanish or Portuguese individuals. Its origins are debated, but it is believed to derive from the name "Diego," which was a common name among Spanish-speaking people. The term emerged in the early 20th century, reflecting the nativist attitudes and prejudice faced by Italian immigrants. It has since been recognized as offensive and is largely avoided in contemporary discourse.
