Cecil Champain Lowis, The Tribes of Burma — The Karens (1910)
“ They are almost the only Lower Burma Karens who have preserved their tribal homogeneity. The Pwos and Sgaws are largely dwellers in the plains and foot-hills whom alien surroundings have moulded into some kind of uniformity, but they have never really coalesced. The Upper Burma Karens as a whole, partly on account of the rugged nature of their separating hills, partly as a result of their leaning towards endogamy show an ever-growing tendency to disintegrate into separate clans differing widely from each other in dress, dialect and custom. ”
