The hardscrabble people of northern England, the Scottish lowlands and Ulster were cannon fodder for the English-Scottish and English-Irish border wars.
They were uncouth, fierce, stubborn and rebellious, and hard to get along with.
When the border wars ended, they were encouraged to leave for colonial America. Once here, they were encouraged to leave the coastal settlements for the Appalachian back country.
David Hackett Fischer, in Albion’s Seed, wrote that they were the last of the four great British migrations whose folkways became the basis of American regional cultures.
Fischer stated that each of the folkways had its own concept of freedom. The Puritans of Massachusetts Bay believed in ordered freedom, the right of communities to live by God’s will and their own laws. The Cavaliers of tidewater Virginia believed in hegemonic freedom, the power to rule and not be ruled. The Quakers of the Delaware Bay believed in reciprocal freedom, the duty to allow others all the freedoms you want for yourself.
The Appalachian backwoodsmen believed in natural liberty, the right to live as you wish without interference by others. They found this liberty in America and felt at home here. They and their descendants, when asked their ancestry, are the most likely to merely answer “American.”
Their desire for natural liberty put them in the forefront of the American westward movement. Kentucky and Tennessee became states before Ohio and Alabama were barely settled from New England and the deep South.
They provide our image of the pioneer West. Daniel Boone, Davy Crockett, Sam Houston and Kit Carson were products of the Appalachian culture.
Together with the indentured laborers of the Deep South, they also provide our image of poor white people.
And more recently, they provide our image of right-wing, gun-loving, evolution-denying, diversity-hating supporters of Donald Trump. This latter image, while not completely false, ignores a lot of history
