Ainsty
Originally a wapentake or subdivision of the West Riding of Yorkshire it later had a unique status as a rural area controlled by the corporation of the city.The Ainsty covered an area to the west of York, bounded by three rivers: the Nidd to the north; the Ouse to the east and the Wharfe to the south.As a result, villages tend to occupy slight rises, and the settlements of the Ainsty are dispersed with some areas, such as Marston Moor, almost completely devoid of buildings.[4] The city of York later claimed jurisdiction over the area under a royal charter of King John granted in the early 13th century.The validity of this charter was a matter of dispute between the city and the Crown, eventually leading to the imprisonment of the mayor in 1280 when it was proved that a clause in the document had been altered.
