Written by former Provisional Supreme Judge J. Quinn Thornton, this historical account chronicles the 1843 establishment of Oregon's Provisional Government at Champoeg and its subsequent legislative evolution. The narrative details the transition of the Willamette Valley from a loosely governed frontier outpost into an organized American political entity, emphasizing the drafting of its organic laws and the urgent lobbying for official U.S. territorial recognition. A keen insight drawn from the text is how Thornton’s intense personal vanity and staunchly anti-British prejudices transform this administrative history into a highly subjective, partisan autobiography. By actively framing himself as the indispensable architect of the 1848 Territorial Act and the primary crusader responsible for explicitly banning slavery in the region, Thornton weaponizes the historical record to settle old political vendettas and artificially inflate his own legacy in Pacific Northwest statecraft.
