Galloway, a district in the SW. of Scotland, co-extensive with Wigtown and Kirkcudbright, though formerly of considerably greater extent; the lack of mineral wealth has retarded its development, and the industry of the population is limited chiefly to agriculture, the rearing of sheep and cattle, and fishing, and it is still noted for a small but hardy breed of horses called Galloways; the province derives its name from Gall-Gael, or foreign Gaels, as the early inhabitants were called, who up to the time of the Reformation maintained the characteristics, language, &c., of a distinct people; in 1455 Galloway ceased to exist as a separate lordship; in the extreme S. of Wigtown is the bold and rocky promontory, the Mull of Galloway, the extremity of the peninsula called the Rhinns of Galloway; the Mull, which is the most southerly point in Scotland, rises to a height of 210 ft., and is crowned by a powerful lighthouse.
