The United States and Great Britain established in 1818 joint claim over the Oregon Territory - the region north of Spanish controlled Upper California up to the southern boundary of Russia's Alaska Territory at North latitude 54°40'. By the late 1830's this arrangement was beginning to fall apart. In the 1840's the expansionist Democrats, including their 1844 presidential candidate, James Polk, claimed the entire region for the United States. Their expansionist desires were expressed by Polk's famous campaign slogan, "Fifty-four Forty or Fight!" The slogan also became a rally cry for Americans desiring to settle the territory. Following Polk's election, the dispute was resolved by the 1846 Treaty of Oregon, which struck a compromise that fixed the U.S./Canadian boundary at 49º North.

This nicely detailed French map presents the Republic of Texas in its smaller configuration with its southern border on the Nueces River (the borders are engraved but not colored). Mexico is control of the entire Southwest including California. Oregon's territorial claims extend up into Canada to North latitude 54°40', a reflection of the Oregon boundary dispute. In the Great Basin, the lakes Timpanogos and Teguayo are partially delineated, with conjectural rivers flowing from them to the Pacific. A vast Territoire du Missouri dominates the United States west of the Mississippi. The map is enclosed in a frame-style border. Directed and lettered by Lale.
