Following the Mexican Revolution (1910–20), which generated significant new streams of Mexican migration to the border, anti-Mexican antipathy gained increasing expression in U.S. immigration policy: the United States created the Border Patrol as part of the Immigration Bureau in the Department of Labor in 1924; began to criminalize unauthorized entry in 1929; and policed immigrants and Mexican American communities with deportation campaigns during the Great Depression and the years of the Bracero Program.

33 More precisely, Beth Lew-Williams has recently argued that policy makers were ambivalent about barring Chinese immigration, and originally intended the 1882 law to merely “restrict” Chinese immigration. It was the anti-Chinese violence in the U.S. West, Lew-Williams argues, that compelled the federal government to expand the policy against Chinese immigration from one of “restriction” to one of “exclusion.” Lew-Williams, Beth, The Chinese Must Go: Violence, Exclusion, and the Making of the Alien in America (Cambridge, MA: Harvard University Press, 2018)CrossRefGoogle Scholar.

38 Four years later, in Fong Yue Ting v. United States, 149 U.S. 698 (1893), the Supreme Court affirmed the federal power to exclude and remove noncitizens as well; although the Constitution provides no explicit deportation power, the Supreme Court upheld the government's power to remove and expel noncitizens, again arguing that such a power was inherent to sovereignty.

39 See also The Late Corporation of the Church of Jesus Christ of Latter-Day Saints v. United States, 136 U.S. 1 (1890), which soon followed on the heels of Chae Chan Ping v. United States and included similar questions about territoriality, sovereignty, and the power of the U.S. federal government over Utah territory and Mormon affairs.

40 United States v. Kagama, 118 U.S. 375 (1886), 384–85 (emphasis added). The case involved a constitutional challenge to the 1885 Major Crimes Act, a federal law that extended U.S. criminal jurisdiction to certain major crimes committed between Native Americans.

42 In a recent issue of the new journal Modern American History, Margaret Jacobs even pointed out that “[t]he curious case of the federal government's ‘plenary power’ over both indigenous peoples and immigrants points to a productive area of inquiry,” but this important observation is buried in a footnote. Jacobs, Margaret D., “Seeing Like a Settler Colonial State,” Modern American History 1 (July 2018), 260n13CrossRefGoogle Scholar. In-depth connections between the development of inherent plenary powers in the case of “Indians, aliens, and territories” has been made mostly by legal scholars, but their analytical connections have remained largely at the doctrinal or theoretical level. See Saito, Natsu Taylor, “The Plenary Power Doctrine: Subverting Human Rights in the Name of Sovereignty,” Catholic University Law Review 51, no. 4 (2002), 1,115Google Scholar; Cleveland, Sarah H., “Powers Inherent in Sovereignty: Indians, Aliens, Territories, and the Nineteenth Century Origins of Plenary Power over Foreign Affairs,” Texas Law Review 81 (Nov. 2002), 3Google Scholar. Rather than treating the cases as a chronological coincidence—in other words, as matters of legal and political development that converged around the same time—I am currently working on a book that points to a spatial connection. Taking a more granular look at the West (especially California and then the U.S.-Mexico border region) I am examining how the Indian Wars in the West transformed into battles against Chinese immigration along the U.S.-Mexico border.

43 This does not mean, of course, that the United States is any less imperial today, either abroad or in the domestic context.
