The Darkskins were descendants of the core or founding group of the Geledi; the Lightskins had a separate line of descent, claimed partly Arab origin, and resembled the Arab populations of the old coastal towns. They had been completely Somalized, however. The wealth and position of the Lightskins were similar to that of the Darkskins, but the latter had precedence in certain traditional rites.
Each lineage (which consisted of perhaps 300 to 400 persons), or Darkskins, Lightskins, and habash, had its own set of elders and constituted a diya-paying group vis-à-vis the others, but was bound in a common contract concerning rates of compensation for injuries. In principle, habash lineages had equal rights under this system. Each lineage controlled specific segments of the land and allocated to an individual male as much as his family could cultivate. However, only the habash were subsistence cultivators in the nineteenth and the early twentieth centuries. The nobles, whether Darkskins or Lightskins, cultivated much larger areas by means of slave labor and exported surpluses via the coastal ports to Arab lands.
