This thesis is a study of Sir Frederick Jackson, an early British explorer and administrator between 1880 and 1917 focusing on three main facets of his career those being his early days as an explorer, his administration in Kenya, and then his governorship of Uganda. Within these three main focal points, various important historical topics such as the Uganda Railway, the Maasai Move, and the planter and peasant dilemma in Uganda are discussed in relation to Jackson's position at that moment of his career in order to shed some light on Jackson and the early colonial period in Africa.
