West New Jersey: Polity Style: 1680-1688

1/11 Jul 1676	the Province of New Jersey is divided into East New Jersey and West New Jersey in accordance with a quintite or quintipartite (five-party) indenture signed by Sir George Carteret and three trustees of Edward Byllynge's interest on 1/11 Jul 1676 (New Jersey Archives, Series 1, 1:205-219)
16/26 Aug 1677	the commissioners appointed by the trustees of Byllynge and a group of settlers reached New Castle on the Delaware River on 16/26 Aug 1677 and subsequently landed near Raccoon Creek on the Jersey side of the river (Smith's History of New Jersey, p. 93)
6/16 Aug 1680	the trustees of Byllynge are granted the right of government of West New Jersey, in accordance with an indenture of grant signed by the Duke of York on 6/16 Aug 1680 (New Jersey Grants, Concessions and Original Constitutions, pp. 412-419) [1]
6/16 Aug 1680 - 18/28 Aug 1688	Province of West New Jersey
18/28 Aug 1688	the Province of West New Jersey is placed under the administration of a Governor and Council of the Territory and Dominion of New England in accordance with letters patent (commission) issued by command of the King of England on 7/17 Apr 1688, which was read and published in Burlington on 18/28 Aug 1688 (New York Colonial Documents, 3:554-555)

The deed of partition of New Jersey expressly divided the territory into "East New Jersey" and "West New Jersey," but the trustees of Edward Byllynge, proprietor of the western division, were not initially granted the right of government. Authority over the area remained under the jurisdiction of the governor of the Duke of York's American territories Edmund Andros. The Duke transferred the government only on 6/16 Aug 1680, a date that may be conditionally accepted as the establishment of the Province of West New Jersey.
