Organized from Ripley County February 14, 1845, with a population of 750; and named for Oregon Territory. The controversy between Britain and the United States over the possession of this territory, which gave rise to the slogan "Fifty-four forty or fight," was a live issue at the time, finally settled in favor of the United States in 1846. Oregon Territory was organized in 1848, and became a state in 1859. It was named for the Oregon River, now the Columbia. The name is of Indian origin, but its precise meaning is uncertain.
