Gilman, E. "[United States (after the Treaty of Guadalupe Hidalgo)]." 1848. Map. Description: The map illustrates the territorial changes in the United States following the Treaty of Guadalupe Hidalgo in 1848, which transferred Upper California and New Mexico to the U.S. and confirmed its claim to Texas.
