Troy is a city in the US State of New York and the seat of Rensselaer County. The city is located on the western edge of Rensselaer County and on the eastern bank of the Hudson River. Troy has close ties to the nearby cities of Albany and Schenectady, forming a region popularly called the Capital District. The city is one of the three major centers for the Albany Metropolitan Statistical Area (MSA), which has a population of 1,170,483. At the 2010 census, the population of Troy was 50,129. Troy's motto is Ilium fuit, Troja est, which means "Ilium was, Troy is".
Before European arrival, the area was settled by the Mahican Indian tribe. The Dutch began settling in the mid 17th century; the patroon Kiliaen van Rensselaer called the area Pafraets Dael, after his mother. Control of New York passed to the English in 1664 and in 1707 Derick Van der Heyden purchased a farm near today's downtown area. In 1771 Abraham Lansing had his farm in today's Lansingburgh laid out into lots. Responding to Lansing's success to the north, in 1787, Van der Heyden's grandson Jacob had his extensive holdings surveyed and laid out into lots as well, calling the new village Vanderheyden.
In 1789, Troy got its current name after a vote of the people. In 1791, Troy was incorporated as a town and extended east across the county to the Vermont line and included Petersburgh. In 1796 Troy became a village and in 1816 it became a city. Lansingburgh, to the north, became part of Troy in 1900.(Wikipedia)
