How did the assassination of Tom Mboya affect ethnic tensions in Kenya?

The assassination of Tom Mboya in July 1969 significantly worsened existing ethnic tensions in Kenya, particularly between the Kikuyu people, who were dominant in Jomo Kenyatta’s administration, and the Luo community, to which Mboya belonged.12

Although Mboya did not pursue ethnic-based politics, his death occurred against a backdrop of growing political alienation following the fall from grace of Oginga Odinga, another prominent Luo leader. Many Luo supporters became convinced that a Kikuyu plot, centered on President Kenyatta, existed to threaten Luo interests. This perception of an ethnic conspiracy was further fueled by government policies, such as the distribution of land to wealthy individuals—many of whom were Kikuyu—and the increasing presence of Kikuyu in the military officer corps.2

The resulting division deepened later in 1969 when the government banned the Kenya People’s Union and arrested its leaders, solidifying the belief among critics that the state was acting to benefit the Kikuyu at the expense of other ethnic groups.2
