This map of North America in the 1850s shows the 27 states and 8 territories of the United States of America of the time. It should be noted that during the Kays Administration, the naming conventions of US states and territories began to shift towards the names of the earliest Presidents of the United States. The Adams Territory was the remainder of the old Missouri Territory, comprised of land taken during the War of 1804, acquired during President Adam's tenure as president. The Jefferson Territory was the remainder of the Oregon Country, the final rights to which had been negotiatied in the Transcontinental Treaty by the Jefferson administration. Not coincidentally, the naming of these two territories meant one each was from the Federalist and Democratic (previously called Democratic-Republican) parties. For the remaining territories in the Southwest along the border, the Colorado Territory had already been named under the older nomenclature system, but some argued for renaming the territory using the presidential system. Schulze was the president under which the territory had been acquired, but it was felt that he was too 'recent' a president to name a territory after, and so some suggested that the territory be renamed Washington, for the founding president of America, as it seemed wrong to have territories named after other founding-father presidents but not
the founding president. In the end, Colorado Territory retained its name, but a new territory was created out of the old Missouri Territory lands below the 40th parallel, which was named Washington Territory.
