Definition of chauvinistic

"Chauvinistic" originates from the French soldier Nicolas Chauvin, a fervent supporter of Napoleon Bonaparte. In the early 19th century, Chauvin's unwavering loyalty and exaggerated patriotism became synonymous with excessive nationalism and blind devotion to one's country. The word "chauvin" was first used in the play "La Cocarde Tricolore" (1831) to describe a character based on Chauvin. By the mid-19th century, "chauvinism" and "chauvinistic" entered the English language to describe excessive patriotism and blind allegiance to a particular group or belief.
