Jaakko Ilkka

Jaakko Pentinpoika Ilkka (1545, Ilmajoki – January 27, 1597) was a Finnish yeoman and trader. He is remembered for leading the Cudgel War of 1596; at its end, and the peasants' defeat on January 1–2, 1597, he escaped, but was soon recaptured and executed for his part in the fighting.

Ilkka was the subject of an opera by Jorma Panula, composed between 1977 and 1978.
