8.8.2 Mapa de los Estados Unidos De Mejico.

The seventh edition known as the "Treaty Map." This map was "the official cartographic reference consulted in negotiating the peace treaty of February 2, 1848, which terminated the Mexican war..." (Martin). The first of seven issues in 1847, this is easily identifiable by having only two inset maps in the Gulf of Mexico (later issues have four). The twelfth edition was also used as a treaty map. This copy folds into red cloth covers 15x10, with "Mexico" stamped in gold, and with "Statistics of the Republic of Mexico" pasted on the inside front cover. Signature of Cornelius S. Van Alstine, U.S. Navy, on verso of map. Streeter refers to this seventh edition as "the most important edition of the Disturnell map." Map is in full color.

The Treaty of Guadalupe Hidalgo was signed in 1848, and the Disturnell Treaty map was used to negotiate the land cession. The Mexican government was required to sign away their land or else suffer continued US military occupation. As a result of the treaty, Mexico surrendered 55 percent of its country’s territory (present-day Arizona, California, New Mexico, and parts of Colorado, Nevada, and Utah). The Texas border was also set at the Rio Grande river. The United States paid Mexico $15 million for war-related damage to Mexican property. In addition to changes in the size of their territory, how do you think Mexico changed as a result of the war’s outcome? How do you think the United States changed?
The Disturnell Treaty map reveals the extent of Mexican lands in its northern territory prior to the end of the war. On this map you can see how California was organized under Mexican law, extending east to the Great Salt Lake in what is Utah today. Note the Mexican towns located along the Rio Grande river in New Mexico, along the Gila River in what is Arizona today, and along the coastal region of Alta California. The rest was inhabited by indigenous populations, who, under Mexican law, were citizens. Note also that Texas was already seen as part of the United States and so not negotiated under the treaty.
