Clackamas was one of the four original Oregon districts created by Oregon's Provisional Legislature on July 5, 1843 along with Twality (later Washington), Champooick (later Marion), and Yamhill. The four districts were redesignated as counties in 1845. At the time of its creation, Clackamas County covered portions of four present-day states and a Canadian province. The Columbia River became the northern boundary of the county in 1844.
Oregon City was also the site of the only federal court west of the Rockies in 1849, when the city of San Francisco was platted. The plat was filed in 1850 in the first plat book of the first office of records in the West Coast and is still in Oregon City.
In contrast with the more liberal and cosmopolitan Multnomah County to the north, and the more affluent Washington County to the west, Clackamas county has espoused a blue-collar, yet conservative political outlook. It is the headquarters of Lon Mabon, whose Oregon Citizens Alliance has worked to pass a number of anti-homosexual initiatives, and where Bill Sizemore, who has championed various anti-government initiatives for most of the 1990s, has his base.
