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.
