Etymology

Origin of kaiser

1150–1200; < German ≪ Latin Caesar emperor, special use of proper name ( see Caesar); replacing Middle English keisere, (north) caisere < Old Norse keisari ≪ Latin as above; compare Old English cāsere

Explanation

Historically, a kaiser was a German or Austrian emperor. In North America, it's also a delicious crusty roll. This royal title goes all the way back to the Holy Roman Emperors of the 10th century, who called themselves kaiser, from Caesar, "emperor or ruler," (a reference to Julius Caesar). The term was used throughout the German Empire, until its end in the 20th century. Kaiser rolls resemble crowns and originated in Austria, where they're known as Kaisersemmel. They're named after Austrian Kaiser Franz Joseph I, who ruled from 1848 to 1916.
