The Rahanweyn (Somali Maay: Reewing; traditional Somali: Raxanweyn, Arabic: رحنوين) is a Somali clan, composed of two major sub-clans, the Digil and the Mirifle. It makes up about 20% of the population of Somalia, and is one of the five major Somali clans residing in the Horn of Africa.
The Digil sub-clan mainly consists of farmers and coastal people, while the Mirifle are predominantly nomadic pastoralists.
According to the Rahanweyn, Somalis are linguistically grouped into Mai Terreh and Maxaa Tiri. The speakers of Mai Terreh (also known as Mai-Mai or Af-Maay) are the Rahanweyn, while the speakers of Maxaa Tiri (i.e. Standard Somali) belong to other clans (Darod, Dir, Hawiye and Isaaq).
The Digil and Mirifle are mainly concentrated in southern Somalia, including Mogadishu, Upper Juba (Gedo, Bay, Bakool, most parts of Middle Juba) and Lower Shebelle. They are also found in the Somali Region of Ethiopia and the North Eastern Province of Kenya.
There is no clear agreement on the clan and sub-clan structures and many lineages are omitted. The following listing is taken from the World Bank's Conflict in Somalia: Drivers and Dynamics from 2005 and the United Kingdom's Home Office publication, Somalia Assessment 2001.
In the south central part of Somalia the World Bank shows the following clan tree:
Christian Bader lists the principal Digil and Rahanweyn subclans as follows:
- 'Ali Jiiddu
- Iise Tunni
One should note that the Garre do not actually claim descent from Rahanweyn or Digil and Mirifle. Only in the Southern Somalia do they come under the Rahanweyn confederation due to their isolation from other Garre's and assimilation into the Digil umbrella. Garre are divided into the Tuff and Quranyow sub-clans. While the Tuffs are further divided into the Ali and Adola groups, the Quranyow are divided into the Asare and Furkesha. Kuranyo(Quranyow who was married to Tuuf's daughter make and agnatically descend from Dir son of Irrir son of Samaale.
