MULEMBE IN NUMBERS: Vihiga County Population

Vihiga is the smallest county in Mulembe, both by population and area. It is home to the Mulembe houses of: Maragoli, Anyole and Tiriki. Further, it’s also home to the Terik whose umbilical cord is in Nandi. Historically it’s acknowledged that Vihiga is one the most heavily densely populated areas not only in Kenya but also the Great Lakes and Africa. This population pressure has occasioned out migration of brothers from these Mulembe houses to as far as Northern Tanzania.

As a result, there is a large diaspora population from the houses of Mulembe in modern day Vihiga. Most members of this ‘Mulembe diaspora’ are found in the counties of: Nairobi, Kisumu, Migori, Trans Nzoia, Bungoma, Uasin Gishu and Kakamega. The most recent evidence of existence of this ‘Mulembe diaspora’ is found in the unfortunate case of the October 10th, 2019 Chesumei evictions in Nandi county. In Kaptobongen village where the evictions took place, over 500 mulembe families were put out in the cold.

MULEMBE IN NUMBERS: Busia County Population

The Mulembe houses from modern day Busia county, the BaKhayo, BaSamia and BaNyala, suffered most in the late 1890’s following the scramble and partition of Africa. Families were separated by imaginary lines that cut through bonds that had been nurtured through ages. These lines persist today as the boundary between Kenya and Uganda. Nonetheless, of all of Kenya’s border points, the Kenya- Uganda border should be the most fluid of all. This is because in spite of the eugenic aims behind creation of borders, families continue to live, commune and eat together.

MULEMBE IN NUMBERS: Trans Nzoia County Population

Traditionally, Trans Nzoia county is listed among the North Rift counties of Kenya. Although this county that’s often termed as the bread basket of Kenya is cosmopolitan, a majority of its inhabitants are from the Mulembe house of BaBukusu. It is for this reason, and the undeniable cultural imprint of Bukusu culture in the persona of this county, that we list it among Mulembe counties.

Consider for instance the hit song ‘Muliro’ by the late Bukusu music maestro Isaac Kisache. In this dirge, Kisache mourns the legend of Mulembe hero Masinde Muliro. In particular, he his thankful for Muliro’s role in conquering ‘Forkland’ thus facilitating the migration of Babukusu into Trans Nzoia.
