What is "silcis"

The Silcis (sometimes spelled "Sil'is" or "Seles" in historical texts) are a Somali subclan. They are part of the Gorgate subclan of the Hawiye clan, which is one of the major clans of Somali people. The Silcis inhabit the traditional coastal region of Benadir in the southern part of Somalia. This region should not be confused with the much smaller present day Banaadir administrative region ( gobol) which contains Somalia’s capital Mogadishu. Silcis live, or have historically lived, along the Shabeelle River in towns such as Afgooye and Jowhaar, as well as along the coast, especially in Mogadishu and Warsheekh.
