Trans-Appalachia can be divided into four sub regions: 1) the
Old Northwest Territory that encompasses the current states of Ohio, Indiana, Illinois, Michigan, Wisconsin and Minnesota, 2) the Old Southwest Territory represented by the present states of Kentucky, Tennessee, Alabama, Mississippi, 3) Florida, and 4) the territory of upstate New York and southeast Canada.
A similar name, trans-Allegheny, has much the same usage (usually as an adjective) and refers to the
Allegheny Mountains, the northern portion of the Appalachians.
History
Beginning in the 18th century, as open land east of the Appalachian Mountains became increasingly scarce, the region started to receive significant numbers of migrants. The Appalachian mountains were bypassed for Trans-Appalachia's better farmland and access to waterways.
Much of 18th century Trans-Appalachia, especially the Ohio River Valley, was defined by conflict over territory between the British, French, and Native Americans. Although the Proclamation of 1763 after the
Seven Years War prohibited further settlement, significant migration to the region continued throughout the 1760s and 1770s. This caused further conflict with Native Americans, such as
Pontiac's War from 1763 to 1764. After the Revolutionary War, America formally acquired the land of Trans-Appalachia through peace treaties. This spurred a new wave of migration that would catapult the region to increasing prominence.
