Buffalo is a city in the U.S. state of New York. It lies in Western New York at the eastern end of Lake Erie and at the head of the Niagara River on the Canada–United States border. It is the second-most populous city in New York, with a population of 278,349 at the 2020 census. The Buffalo–Niagara Falls metropolitan area, with over 1.16 million residents, is the 51st-largest metropolitan area in the United States. Buffalo is the county seat of Erie County.
Before the 17th century, the region was inhabited by nomadic Paleo-Indians who were succeeded by the Neutral, Erie, and Iroquois nations. In the early 17th century, the French began to explore the region. In the 18th century, Iroquois land surrounding Buffalo Creek was ceded through the Holland Land Purchase, and a small village was established at its headwaters. Buffalo was selected as the terminus of the Erie Canal in 1825, which led to its incorporation in 1832 and stimulated its growth as the primary inland port between the Great Lakes and Atlantic Ocean. Transshipment made Buffalo the world's largest grain port in that era. After the coming of railroads greatly reduced the canal's importance, the city became the second-largest railway hub (after Chicago), and the city came to be dominated by steel production by the 20th century. Later, deindustrialization and the opening of the St. Lawrence Seaway saw the city's economy decline and diversify. It developed its service industries, such as health care, retail, tourism, logistics, and education, while retaining some manufacturing.
