===Results===
The land that the Treaty of Guadalupe Hidalgo brought into the United States became, between 1850 and 1912, all or part of nine states: [[California]] (1850), [[Nevada]] (1864), [[Utah]] (1896), and [[Arizona]] (1912), as well as, depending upon interpretation, the entire state of Texas (1845), which then included part of [[Kansas]] (1861); [[Colorado]] (1876); [[Wyoming]] (1890); [[Oklahoma]] (1907); and [[New Mexico]] (1912). The area of domain acquired was given by the Federal Interagency Committee as 338,680,960 acres.<ref name="books.google.com">{{cite book|title=Our Public Lands|department=Issued quarterly by United States Department of the Interior Bureau of Land Management |date=1958-01-01|page=7|url=https://books.google.com/books?id=eFPWo3AcWi8C&pg=RA3-PA7}}</ref> The cost was $16,295,149 or approximately 5 cents an acre.<ref name="books.google.com"/> The remainder (the southern parts) of New Mexico and Arizona were peacefully acquired under the [[Gadsden Purchase]], which was carried out in 1853.

However, the [[American Civil War]] delayed the construction of such a route, and it was not until 1881 that the [[Southern Pacific Railroad]] finally was completed as a second transcontinental railroad, fulfilling the purpose of the acquisition.<ref>{{cite book |first=David |last=Devine |title=Slavery, Scandal, and Steel Rails: The 1854 Gadsden Purchase and the Building of the Second Transcontinental Railroad Across Arizona and New Mexico Twenty-Five Years Later |location=New York |publisher=iUniverse |year=2004 |isbn=0-595-32913-6 }}{{Self-published source|date=October 2019}}</ref>
