4.5
"The prolonged, two-year reconciliation conference held in Kenya and the resulting interim administration, implemented under the dominant tutelage of Ethiopia, are generally considered to have failed to live up to the expectations of the Somali people. The state structure was built on the foundation of a clan power segregation system known as 4.5 (four-point-five). This means the separation of the Somali people into four clans that are equal and, as such, pure Somali, against an amalgamation of various clans and communities that are unequal to the first group and, hence, considered “impure” or less Somali. The lumping together of all the latter communities is regarded as equivalent only to a half of the share of a clan."
