In addition to these conflicts, European nations also used their North American colonial possessions to wage wars with one other colonial territories in the event of a larger war in Europe or for the control of resources. A number of colonial territories saw conflict with rival colonies as a result of a larger European war. Several North American colonies were attacked by other European powers in conflicts such as the Anglo-Spanish War of 1585 to 1604, and the Eighty Years' War. Campaigns of colonial conquest were also fought during this time, with the Dutch conquest of New Sweden during the Second Northern War, and the English conquest of New Netherland during the Second Anglo-Dutch War. By the beginning of the 18th century, the kingdoms of England, France, and Spain were the only remaining colonial powers on the North American mainland.
