Cleveland is a city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located along the southern shore of Lake Erie, it is situated across the Canadian border and approximately 60 mi (97 km) west of the Ohio–Pennsylvania state line. Cleveland is the most populous city on Lake Erie and second-most populous city in Ohio, with a population of 372,624 at the 2020 census. The Cleveland metropolitan area, with an estimated 2.17 million residents, is the 34th-largest metropolitan area in the United States.
Cleveland was founded in 1796 near the mouth of the Cuyahoga River as part of the Connecticut Western Reserve in modern-day Northeast Ohio by General Moses Cleaveland, after whom the city was named. The city's location on the river and the lake shore allowed it to grow into a major commercial and industrial metropolis by the late 19th century, attracting large numbers of immigrants and migrants. It was among the top 10 largest U.S. cities by population for much of the 20th century, a period that saw the development of the city's cultural institutions. By the 1960s, Cleveland's economy began to slow down as manufacturing declined and suburbanization occurred.
