Pike County, Illinois
Pike County was formed in January 1821 out of Madison County. It was named in honor of Zebulon Pike, leader of the Pike expedition in 1806 to map out the south and west portions of the Louisiana Purchase. Pike served at the Battle of Tippecanoe, and was killed in 1813 in the War of 1812.
