The Great Wagon Road was an improved trail through the Great Appalachian Valley from Pennsylvania to North Carolina, and from there to Georgia in colonial America.
The heavily traveled Great Wagon Road was the primary route for the early settlement of the Southern United States, particularly the "backcountry". Although a wide variety of settlers traveled southward on the road, two dominant cultures emerged. The German Palatines and Scotch-Irish American immigrants arrived in huge numbers because of unendurable conditions in Europe. The Germans (also known as Pennsylvania Dutch) tended to find rich farmland and work it zealously to become stable and prosperous. The other group (known also as Presbyterian or Ulster Scots) tended to be restless, clannish, and fiercely independent; they formed what became known as the Appalachian Culture. Partly because of the language difference, the two groups tended to keep to themselves.
Beginning at the port of Philadelphia, where many immigrants entered the colonies, the Great Wagon Road passed through the towns of Lancaster and York in southeastern Pennsylvania.
A wagon train is a group of wagons traveling together. In a military context, a baggage train was the wagon train that followed an army with supplies and ammunition.
In the American West, settlers traveling across the plains and mountain passes in covered wagons banded together for mutual assistance. Although wagon trains are associated with the Old West, the Trekboers of South Africa also traveled in caravans of covered wagons.
Virtually all US trails originated in Independence, Missouri, a gateway to the American West.
Perhaps the most famous wagon train trail was the Oregon Trail which had a span of over 2,000 miles. Other paths included the [[]], the Chisholm Trail, the California Trail (which split southwestward from the Oregon Trail), the Mormon Trail, and the Old Spanish Trail.
Although "wagon train" suggests a line of wagons, when terrain permitted, wagons would often fan out and travel abreast to minimize the amount of dust each wagon encountered.
