territory as part of New France. In 1666, French settlers erected Fort Sainte Anne on Isle La Motte, the first European settlement in Vermont. The "violent" 1638 New Hampshire earthquake was centered in the St. Lawrence Valley and reported throughout New England. This was the first seismic event noted in Vermont. In 1690, a group of Dutch-British settlers from Albany established a settlement and trading post at Chimney Point, west of present-day Addison. During Dummer's War, the first permanent English settlement was established in 1724 with the construction of Fort Dummer. It was intended to protect the nearby settlements of Dummerston and Brattleboro. From 1731 to 1734, the French constructed Fort St. Frédéric, which gave them control of the New France–Vermont frontier region in the Lake Champlain Valley. With the outbreak of the French and Indian War in 1754, the North American front of the Seven Years' War between the French and British, the French began construction in 1755 of Fort Carillon at present-day Ticonderoga, New York. The British failed to take either fort between 1755 and 1758. In 1759, a combined force of 12,000 British regular and provincial troops under Sir Jeffery Amherst captured Carillon in the Battle of Ticonderoga, after which the French abandoned Fort St. Frédéric. Amherst constructed Fort Crown Point next to the remains of the Fort St. Frédéric, securing British control over the area. Following France's loss in the French and Indian War, through the 1763 Treaty of Paris, it ceded control of land east of the Mississippi River to the British. The Crown attempted to limit colonial settlement to lands east of the Appalachians, in order to prohibit encroachment on Native American lands. The territory of Vermont was divided nearly in half in a jagged line running from Fort William Henry in Lake George diagonally north-eastward to Lake Memphremagog. With the end of the war, new settlers arrived in Vermont. Ultimately, Massachusetts, New Hampshire and New York all claimed this frontier area. On July 20, 1764, 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 45 degrees north latitude. New York refused to recognize the land titles known as the New Hampshire Grants (towns created by land grants sold by New Hampshire Governor Benning Wentworth) and dissatisfied New Hampshire settlers organized in opposition.
