Passage: When the English arrived, the colony somewhat vaguely included claims to all of the present U.S. states of New York, New Jersey, Delaware and Vermont, along with inland portions of Connecticut, Massachusetts and Maine in addition to eastern Pennsylvania. Much of this land was soon reassigned by the crown, leaving the territory of the modern State of New York, including the valleys of the Hudson and Mohawk Rivers, and future Vermont. The territory of western New York was disputed with the Iroquois Indian nation, and also disputed between the English and the French from their northern colonial province of New France (modern eastern Canada). Vermont was disputed with the Province of New Hampshire to the east.

Question: Which area was being disputed over?
territory of western New York
