Most of the county is within the Nez Perce Indian Reservation, though Native Americans comprise less than 6% of the county population. Similar to the opening of lands in Oklahoma, the US government opened the reservation for white settlement in November 1895. The proclamation had been signed less than two weeks earlier by President Cleveland.
Lewis County is named for Meriwether Lewis, a co-leader of the Lewis and Clark Expedition.
