The Digil sub-clan mainly consists of farmers and coastal people, while the Mirifle are predominantly nomadic pastoralists. According to our constitutional law, Somalis are linguistically grouped into Mai Terreh and Maxaa Tiri. The vast majority of the Somalis who speak Mai Terreh are the Rahanweyn, while the speakers of Maxaa Tiri belong to other clans.
The Rahanweyn clan were mentioned as the people of Reewing who lived in the fertile lands and coastal provinces and were very wealthy and powerful people during the antiquity period in southern Somalia. They were said to be a sub group of Barbara or Barbaroi people ancestors of the Somali people. Along with Hawiye, Rahanweyn clan also came under the Ajuran Empire control in the 13th century that governed much of southern Somalia and eastern Ethiopia, with its domain extending from Hobyo in the north, to Qelafo in the west, to Kismayo in the south. At the end of the 17th century, the Ajuran Sultanate was on its decline, and various vassals were now breaking free or being absorbed by new Somali powers. One of these powers was the Geledi Sultanate who was established by Ibrahim Adeer, who was an Ajuran general at that time, successfully pushed back the imperialAjuran army out of Afgooye. He subsequently established the Geledi sultanates ruling house, the Gobroon dynasty, after having first defeated the Ajuran vassal state, the Silcis Kingdom. Geledi Sultanate was a Rahanweyn Kingdom ruled by the noble Geledi clan which controlled the entire Jubba River and extending parts of Shebelle River and dominating the East African trade. The Geledi Sultanate had enough power to force the southern Arabians to pay tribute to the noble Geledi Rulers like Ahmed Yusuf. The Geledi Sultanate was eventually incorporated into Italian SomalilandProtectorate in 1908 by the Geledi ruler: Osman Ahmed who signed multiple treaties with the Italian colonials and the Kingdom ended with the death of Osman Ahmed in 1910. At the turn of 1991 when the Somali central government collapsed, the Rahanweyn clan formed their own autonomous state known as South West State of Somalia which was able to establish its own government, economy, army and flag. The Southwest state was able to successfully keep the stability in southern Somalia.
