Monroe is a town in Orange County, New York, United States. The population was 39,912 at the 2010 census. The town is named after President James Monroe.
The first settlers to this land were American Indians from the Lenni-Lenape Indian nation. The Lenni-Lenape nation consisted of three tribes: the Unulactus, the turkeys; Minsis, the wolf tribe; and the Unamis, the turtle tribe. As white settlers started to move north, the Lenni-Lenape were forced to move west, out of New York and New Jersey into Pennsylvania and later into central North America, under the treaty of Easton, a colonial agreement signed in October, 1758. The British colonial government of the province of Pennsylvania and the Native American tribes in the Ohio country signed this document stating they would be allies in the French and Indian War.
In the early 1700s the lower Hudson Valley region was being mapped out to be divided up under the crown. On March 25, 1707, the "Chessecocks Patent was granted by Queen Anne". The patent confirmed deeds that had been previously acquired by purchase directly from the Lenni-Lenape nation.
