Jayhawker

Jayhawkers is a term that came to prominence just before the American Civil War in Bleeding Kansas, where it was adopted by militant bands affiliated with the free-state cause. These bands, known as "Jayhawkers", were guerrilla fighters who often clashed with pro-slavery groups from Missouri known at the time as "Border Ruffians". After the Civil War, the word "Jayhawker" became synonymous with the people of Kansas. Today the term is a nickname for a native-born Kansan.
