Orange County, NY
History
During the American Revolutionary War the county was a hotbed of Loyalist and anti-Patriot activity. Claudius Smith was a Loyalist marauder whose team robbed and terrorized citizens; he was hanged in Goshen in 1779 for allegedly robbing and killing Major Nathaniel Strong; two of his sons were also executed for similar crimes. The Mathews family of Blooming Grove were active Loyalists; Fletcher Mathews was a sympathizer and sometime associate of Smith, and his brother David Mathews was Mayor of New York City during its British occupation for the entirety of the war.In 1798, after the American Revolutionary War, the boundaries of Orange County changed. Its southern corner was used to create the new Rockland County, and in exchange, an area to the north of the Moodna Creek was added, which had previously been in Ulster County. This caused a reorganization of the local administration, as the original county seat had been fixed at Orangetown in 1703, but this was now in Rockland County. Duties were subsequently shared between Goshen, which had been the center of government for the northern part of Orange County, and Newburgh, which played a similar role in the area transferred from Ulster County. The county court was established in 1801. It was not until 1970 that Goshen was named as the sole county seat.
Due to a boundary dispute between New York and New Jersey, the boundaries of many of the southern towns of the county were not definitively established until the 19th century.
