Waterloo is a village located in the West Central area of the American state of New York.
The village of Waterloo used to be a village of the native Cayuga people which was established around the early 1500s. In the 1600s, the town was visited by explorers, and in 1779 the Sullivan Expedition (a military campaign after the US independence that went after anyone who was loyal to the British Empire) destroyed the town. After being abandoned by the Cayuga, the first new settler arrived in 1795. It was later incorporated twice, once in 1824, and again in 1866 when it claimed to hold the first Memorial Day (later disproven).
The village was named after Waterloo, Belgium.
