Kibaki was an economist

In his last year at Mang’u, Kibaki briefly considered enlisting in the army, but this ambition was thwarted when Kenya’s Chief colonial secretary, Walter Coutts, prohibited members of Kikuyu, Embu, and Meru communities from joining the military.

Kibaki instead attended Makerere University in Kampala, Uganda, where he studied economics, history, and political science. He graduated with a first class honours degree in economics.
After graduation, Kibaki remained in Uganda, working for the Shell Company of East Africa.

He then earned a scholarship entitling him to undertake postgraduate studies at any British university. He chose the London School of Economics, from which he obtained a BSc in public finance, with distinction.
In 1958, he went back to Makerere, where he taught as an assistant lecturer in the economics department until 1961.
