The infamous explorer executed for his cruel treatment of native peoples in the Caribbean was Christopher Columbus. While Columbus is often celebrated for his voyages that opened the Americas to European exploration, his legacy is marred by his brutal treatment of Indigenous populations. Upon reaching the Caribbean, Columbus enslaved many Indigenous people, imposed harsh labor conditions, and implemented violent tactics to maintain control over the territories. His actions led to significant suffering and demographic collapse among native groups. Ultimately, a backlash against his governance led to his arrest and return to Spain in chains, and he was later tried and executed for his misdeeds.
