His death plunged Northumbria into a period of instability and briefly reversed the spread of Christianity in the kingdom.

After a roughly ten-week Atlantic crossing, lookout Rodrigo de Triana sighted land from the Pinta, and Columbus's expedition made its historic first landfall in the Americas at an island in the present-day Bahamas, an event that opened the era of sustained European contact, exploration, and colonization of the Western Hemisphere.

The landing opened the way for widespread European colonization of the Americas, with profound and often catastrophic consequences for its indigenous peoples. The date is still commemorated, and contested, as Columbus Day in various countries.

The law allowed authorities to register whole tribes and castes as habitual criminals, subjecting hundreds of thousands of people to surveillance, forced settlement, and restricted movement without individual evidence of wrongdoing. It targeted groups often associated with nomadic or itinerant trades, entrenching lasting social stigma. The act remained in force until independent India repealed it in 1952, though its legacy of discrimination against so-called denotified tribes persists today.
