Even as California was being accepted into the Union, a new dispute was breaking out between the US and Mexico. The map used for the Treaty of Guadalupe Hidalgo had been inaccurate, meaning that the central part of the US-Mexican boundary was ambiguous. To solve this issue, the US ambassador James Gadsden arranged for the purchase of the disputed region, signing the Gadsden Purchase treaty with Mexico in 1853.
