Racial segregation is a tool of power, not just a matter of social distance.

In short: Racial segregation is the calculated restriction of people to specific areas or institutions based on race. While often viewed as a social phenomenon, it is fundamentally a mechanism of control, historically used to secure advantages for dominant groups by denying others basic rights, mobility, and political agency.

At its core, racial segregation is the practice of separating individuals into distinct groups to enforce hierarchy. Historically, this has manifested as the spatial separation of residences, schools, and public facilities. While modern international standards generally outlaw such practices, defining them as potential crimes against humanity, the historical record reveals that segregation was rarely about mere social preference. Instead, it was a deliberate strategy used by dominant groups—from the Mongols to the Aztecs—to consolidate power and maintain control over subordinated populations.

The American experience illustrates this dynamic through the long struggle for civil rights. Despite the promise of equality in founding documents, the U.S. Constitution originally protected slavery, and the 1857 Dred Scott decision reinforced this by declaring that Black Americans had no rights that white citizens were bound to respect. Even after the Civil War and the passage of the Fourteenth and Fifteenth amendments, segregation persisted as a system of oppression. It was only through sustained, nonviolent protest in the mid-1950s and 1960s that the pattern of segregated public facilities in the South was finally broken.

However, segregation is not limited to a single cultural context. In the Tang dynasty, for example, authorities enforced strict separation between Han Chinese and foreigners, including bans on interracial marriage and property ownership, driven by a desire to maintain ethnic boundaries. Conversely, the Qing dynasty initially employed a more complex strategy, using intermarriage and the integration of Han Bannermen into the military structure to stabilize rule. These examples highlight that segregation is a fluid, political instrument. Whether through the exclusion of 'free Blacks' in 19th-century America or the restrictive edicts of 8th-century China, the practice consistently serves to define who belongs and who is excluded from the benefits of the state.
