26 May 1652

Massachusetts declared an interpretation of its 1628/1629 charter that would make its northern boundary an east-west line through a point three miles north of the most northerly part of the Merrimack River, which it decided later (1 August 1652) was the parallel of 43 degrees, 43 minutes, 12 seconds of north latitude. Massachusetts used this interpretation to claim part of Maine and, until 1740, to create a few towns in present southern Vermont and southwestern New Hampshire. (Van Zandt, 64; Williamson, W. D., 1:337)

12 March 1664

[12 March 1663/1664] King Charles II granted to the Duke of York all territory between the Connecticut and Delaware Rivers, including all of present Vermont. (Swindler, 4:278-280)

29 August 1664

The Duke of York's forces captured New Amsterdam from the Dutch, swiftly took control of the rest of New Netherland, and renamed the province New York; territory included present Vermont. (Flick, 2:80)

21 July 1667

The Peace of Breda, between England and France and the Netherlands, confirmed the English conquest of New York, including present Vermont, from the Dutch. (Farnham, 7:311, 314; Parry, 10:231)

30 July 1673

Dutch forces recaptured the territory of former New Netherland, implicitly including present Vermont. (Flick, 2:93)

9 February 1674

[9 February 1673/1674] The Treaty of Westminster ended the Anglo-Dutch War and restored conquered colonies to their pre-war jurisdictions. New York, and implicitly, present Vermont, returned to the jurisdiction of England. (Parry, 13:136)

29 June 1674

Following the Treaty of Westminster (9 February 1673/1674) King Charles II regranted to the Duke of York the territory he had first granted on 12 March 1663/1664, including present Vermont. (Parry, 13:136; Swindler, 4:282)

1 November 1683

ALBANY (N.Y.) created by New York from non-county area. The northern limits were not specified but were understood to cover present Vermont [not mapped]. (N.Y. Col. Laws, ch. 4/1:121-122)

11 August 1688

New York, including present Vermont, was formally incorporated into the Dominion of New England in accordance with the royal governor's second commission (7 April 1688) and instructions (16 April 1688) from King James II. No change was made in county boundaries. (Docs. of N.Y., 3:537, 543, 554)

18 April 1689

Upon learning of the Glorious Revolution (replacement of King James II by King William III and Queen Mary II) in England, Bostonians imprisoned the royal governor and others, thereby ending the Dominion of New England. Over the next months, New York and other colonies that had been united to form the Dominion had to resume self-government. (Craven, 224; Morris and Kelly, pl. 11)

June 1689

Royal officials lost control of New York, including present Vermont, when local militia captured the fort in New York City (Leisler's Rebellion). Regular government was reinstituted with the arrival of a new royal governor on 19 March 1690/1691. (Andrews, 3:125, 133)

5 August 1740

In settling the boundaries between Massachusetts (which then including Maine) and New Hampshire, King George II defined New Hampshire's western limit as New York. Under this decree New Hampshire challenged New York's 1674 claim to the area of present Vermont by first claiming a western limit equal to Connecticut and Massachusetts (20 miles east of the Hudson River) and later (chiefly in 1761 and 1763) creating in present Vermont more than 100 towns that became known collectively as the New Hampshire Grants. (Farnham, 8:47; Van Zandt, 61)

20 July 1764

ALBANY (N.Y.) implicitly gained all of present Vermont when King George III established the boundary between New Hampshire and New York along the west bank of the Connecticut River, north of Massachusetts and south of the parallel of 45 degrees of north latitude. Although disputes occasionally broke out later, this line became the boundary between New Hampshire and Vermont and has not changed to the present. When New York refused to recognize land titles through the New Hampshire Grants (towns created earlier by New Hampshire in present Vermont), dissatisfied colonists organized in opposition, which eventually led to the creation of independent Vermont in 1777. (Slade, 13-19; Van Zandt, 63)

3 July 1766

CUMBERLAND (N.Y., extinct) created by New York from ALBANY (N.Y.); CUMBERLAND was located entirely within present Vermont. (N.Y. Col. Laws, ch. 1297/4:903-904)

GLOUCESTER (N.Y., extinct) created by New York from ALBANY (N.Y.); GLOUCESTER (N.Y.) was located entirely within present Vermont. (N.Y. Col. Laws, ch. 1559/5:400-402)

12 March 1772

CUMBERLAND (N.Y.) and GLOUCESTER (N.Y.) eliminated when Vermont declared its independence from New York; ALBANY (N.Y.) and CHARLOTTE (now WASHINGTON, N.Y.) eliminated from Vermont. (Slade, 70-73; Van Zandt, 64; Williamson, C., 82-84, map facing 95, 100-102, 112-113)

12 March 1778

Representatives from New Hampshire appeared before the Vermont Assembly and asked that 17 western New Hampshire towns be annexed to Vermont (the so-called East Union).
