Differences in the settlement patterns of eastern and western North Carolina, or the Low Country and uplands, affected the political, economic, and social life of the state from the 18th until the 20th century. The Tidewater in eastern North Carolina was settled chiefly by immigrants from rural England and the Scottish Highlands. The upcountry of western North Carolina was settled chiefly by Scots-Irish, English, and German Protestants, the so-called "cohee". Arriving during the mid- to late 18th century, the Scots-Irish from what is today Northern Ireland were the largest non-English immigrant group before the Revolution; English indentured servants were overwhelmingly the largest immigrant group before the Revolution. During the American Revolutionary War, the English and Highland Scots of eastern North Carolina tended to remain loyal to the British Crown, because of longstanding business and personal connections with Great Britain. The English, Welsh, Scots-Irish, and German settlers of western North Carolina tended to favor American independence from Britain.
