The Doctrine of Discovery is still alive in the modern world.
A decade later, as the U.S. and England argued about dueling discovery claims to the Pacific Northwest, Secretary of State John Quincy Adams and President James Monroe ordered American officials back to the Columbia "to reassert the title of the United States." In August 1818, Capt. James Biddle performed a textbook discovery ritual: In the presence of Chinook Indians on the north side of the Columbia River, he raised the U.S. flag, turned the soil with a shovel and nailed up a lead plate inscribed: "Taken possession of, in the name and on the behalf of the United States by Captain James Biddle." He repeated the performance on the south shore of the Columbia, with a wooden sign declaring American ownership of the region.
