Ellis Island | Alien Enemies | 3

In the immediate aftermath of America’s entry into World War I, federal agents began rounding up hundreds of German nationals and detaining them at Ellis Island, designating them as “alien enemies.” After the war, anti-immigrant sentiment intensified as eugenic theories of racial hierarchy gained popularity. By the 1920s, Americans were willing to accept sweeping changes to the nation’s immigration laws, with the introduction of quotas setting numerical limits on new arrivals. As the country closed the door on immigrants, Ellis Island was transformed into a facility for detention and deportation.
