The Buckeye State
Ohio's nickname is "The Buckeye State" partly because many buckeye trees once covered Ohio's hills and plains. The name buckeye stems from native Americans Indians, who called the nut "hetuck" (meaning buck eye, because the markings on the nut resemble the eye of a deer).
But the national association between Ohio and the buckeye was born during William Henry Harrison's 1840 presidential campaign (Harrison was a Virginia-born Ohioan and military hero). Harrison's opponents claimed he was "better suited to sit in a log cabin and drink hard cider." Harrison's supporters turned this intended criticism into a promotion, dubbing him "the log cabin candidate." They fashioned Harrison's campaign emblem as a log cabin made of buckeye timbers with a long string of buckeyes decorating the walls. Harrison's backers also walked with buckeye canes and rolled whisky barrels in parades.
The campaign gimmick was successful and Harrison ("Old Tippecanoe") beat President Martin Van Buren's bid for re-election. Ohio has since been known as "the buckeye state." The buckeye is also Ohio's state tree.
