After the American Revolution, the Haudenosaunee lost most of their land in New York and Pennsylvania and were forced to live on reservations, including in Canada, as punishment for taking the side of the British Crown in the revolution. Although these reservations included much of the prime real estate in Western New York, including several of the prominent creek and river valleys, the small and fragmented native lands were separated by wide swaths of land that was eventually earmarked for American settlement in what would be known as the Holland Purchase. This dislocation followed years of social disruption due to epidemics of infectious disease and major wars.
