The American Caste System
The American caste system, as conceptualized by scholars like Isabel Wilkerson in her book Caste: The Origins of Our Discontents, operates through a rigid hierarchy where race serves as a primary marker of status, privilege, and exclusion. In this framework, "whiteness" functions as the top tier, granting access to citizenship, voting rights, property ownership, and social mobility, while non-white groups face systemic barriers. From 1790 to 1952, U.S. naturalization laws limited citizenship to "free white persons" (expanded in 1870 to include those of African descent), leading to dozens of "prerequisite cases" where courts adjudicated racial eligibility. These rulings often relied on pseudoscientific ethnology, "common understanding," or geographic origins to determine who qualified as "white," reflecting and reinforcing a caste-like structure that privileged Anglo-Saxon Europeans while marginalizing others. Groups like Irish, Italians, and Eastern European Jews were initially seen as non-white or inferior but assimilated into whiteness through cultural integration, labor movements, and political alliances without major court battles, gaining full privileges by the mid-20th century.
Various ethnic groups sought the "white card" via court rulings to secure naturalization, with mixed outcomes that exposed the arbitrary nature of racial classification. For Middle Eastern and North African immigrants, early 20th-century cases often granted whiteness based on geography or Christianity: Syrians were deemed white in In re Najour (1909) and Dow v. United States (1915), Armenians in In re Halladjian (1909) and United States v. Cartozian (1925), and by 1944, Arab Muslims were included as white for citizenship. Mexicans were classified as white under the Treaty of Guadalupe Hidalgo in In re Rodriguez (1897), enabling citizenship despite social discrimination. However, Asians faced consistent exclusion: Chinese were ruled non-white in In re Ah Yup (1878), Japanese in Ozawa v. United States (1922) where the Supreme Court equated "white" with Caucasian, and Indians in United States v. Bhagat Singh Thind (1923), rejecting scientific Caucasian claims in favor of "common sense" definitions of whiteness. These decisions stripped naturalized Asians of citizenship and barred immigration until racial barriers were lifted in 1952. The rulings underscore how the caste system evolved, gradually expanding whiteness to some groups while entrenching exclusion for others, shaping America's demographic and social hierarchy.
