and ancestor Rahawein, and the individual tribes which constitute the family making about 40% of somali population. The Rahaweyn consists no so much of groups that derive from preceding groups in an extensive hierarchy of segmentation, as simply of large collateral coalitions. The name "Rahaweyn" ( "large crowds") is itself suggestive of federation. The Sab, who number about a quarter millions are found in Somalia south of the Hawiya, mainly along the Juba river. They are segmented into three families: The Digil, Rahaweyn and Tunni of which the last two are numerically the most important. The Rahaweyn and Tunni derive from the Digil who although have been superseded in strength still survive as a small independent confederacy. The Garre joined Rahaweyn constituent sub-clans of Digil, forming a part of the Rahaweyn confederation of clans. known as "Toddobaadi aw Digil" Expansion into the Boranaland The Boran say that long ago they all lived in Liban. The head-quarters of their Kings and their religion (Wak) was near Darar, which is still a great religious centre. Many years ago a number of them made an invasion to the south-west, across the Dawa River, into which the country was occupied by the Wardey, who were a "suffara" (Somali) tribe. The Wardey were driven out and went south-east towards Aji between Wajir and Kismayu. The Invader settled in the conquered country, spread and penetrated south as far as wajir. The true Boran countries are, however Liban and Dirri. Many years after these event there was an invasion from the east, into the most eastern Boran country, by Muslim of Somali origin. These people were camel owners, whereas the Boran are essentially cattle herds. The Muslim drove back the Boran to the West and occupied the country probably up to about latitude 39°30'. After an unknown period they commenced to withdraw eastwards, but not en masse. Those who penetrated furthest west, weakened by the exodus of many of their number, came under the influence of the boran. These are the Gabra Miggo generally "Gabra" and sometime "Gabra Gelli", Gabra in the Boran language signifies "slave" Gelli "Camel". The Garre were the descendants of the Muslim who drove back the boran to the west, but unlike their brethren who have become the Gabra migo, they remained in the country they had occupied in the sufficient numbers to maintain their independence.
