Chapter 4 shows how, as the Wales novel congealed into a stable genre, it began to confront the knotty problem of race. The notorious economic underdevelopment of Wales posed a problem to Scottish Enlightenment-inspired anthropologists who cast climate and religion as the determinants of standardized, stadial socioeconomic progress. Such theories failed to account for the wealth gap between Wales and England, since Wales’s climate was mostly identical to England’s and Wales had come to be understood as the heartland of British Protestantism. As authors struggled to explain Welsh impoverishment, they became increasingly willing to use race to figure the Welsh as different from Anglo-Britons in kind, rather than in degree of social development. Some authors contended that the Welsh were “negroes,” “savages,” and “men of copper,” who deviated from a phenotypically white Britishness, while others insisted they were the progenitors of a pure race destined to rule the world.
