Settled first, the coastal region attracted primarily English immigrants of the early migrations, including indentured servants transported to the colonies and descendants of English who migrated from Virginia. In addition, there were waves of Protestant European immigration, including the British, many Scots Irish, French Huguenots, and Swiss Germans who settled New Bern; many Pennsylvania Germans came down the Shenandoah Valley of Virginia on the Great Wagon Road and settled in the western Piedmont and the foothills of the Blue Ridge. There is a high concentration of Scotch-Irish in western North Carolina. A concentration of Welsh (usually included with others from Britain and Ireland) settled east of present Fayetteville in the 18th century. For a long time the wealthier, educated planters of the coastal region dominated state government.
