Rensselaer County, New York is a county located in the U.S. state of New York, directly across the Hudson River from the state capital of Albany. Established in 1791 from a portion of Albany County, its county seat and largest city is Troy. The county is part of the Capital District metropolitan area and is named for its original patroon, Kiliaen van Rensselaer, a Dutch merchant.

History

The area was originally inhabited by the Mohican people before becoming part of the Dutch patroonship of Rensselaerswyck, granted to Kiliaen van Rensselaer by the Dutch West India Company. Following English conquest, it remained a vast manorial estate under the Van Rensselaer family, with early settlements like Greenbush and Schaghticoke developing in the 17th and 18th centuries. The county was formally created by an act of the New York State Legislature in 1791, with Troy incorporated as a city in 1816 and becoming a major industrial center known for iron and steel production, exemplified by firms like the Albany and Rensselaer Iron and Steel Company. The 19th century saw significant transportation development, including the Champlain Canal, the Troy and Greenbush Railroad, and the influential Rensselaer and Saratoga Railroad. The county was also a hub for social reform, being a center of the Shakers at Mount Lebanon Shaker Society and the site of the Troy Female Seminary, founded by Emma Willard.

Geography

According to the United States Census Bureau, the county has a total area of 665 square miles, of which 655 square miles is land and 10 square miles is water. The western border is defined by the Hudson River, separating it from Albany County and Columbia County. The terrain rises from the river valley to the Taconic Mountains along the eastern border with Massachusetts and the Berkshires, and includes part of the Rensselaer Plateau. Major waterways include the Hoosic River, the Little Hoosic River, and the Wynants Kill. The county contains parts of the Grafton Lakes State Park and the Pittstown State Forest.

The largest ancestry groups include Irish, Italian, German, and English. The population is concentrated in the western river communities like Troy, Rensselaer, and East Greenbush, with more rural areas in the eastern towns such as Stephentown and Berlin.
