The history of Buganda is that of the kingdom of the Baganda people, the largest of the traditional kingdoms in present-day Uganda.
Muteesa I of Buganda, who had been visited by explorers, like John Hanning Speke, James Augustus Grant and Henry Morton Stanley, invited the Church Missionary Society to Buganda. One of the missionaries from the Church Missionary Society was Alexander Murdoch Mackay. Muteesa I never converted to any religion, despite the numerous tries. In 1884, Muteesa died and his son Mwanga II took over. Most of what is known about Muteesa comes from primary sources from various Kiganda researchers and some foreign explorers, notably John Hanning Speke, and the Church Missionary Society. Mwanga was overthrown numerous times, but was reinstated. Mwanga signed a treaty with Captain Lord Lugard in 1892, giving Buganda the status of protectorate under the authority of the British East Africa Company. The British saw this territory as a prized possession.
The twentieth-century influence of the Baganda in Uganda has reflected the impact of eighteenth- and nineteenth-century developments. A series of Kabakas amassed military and political power by killing rivals to the throne, abolishing hereditary positions of authority, and exacting higher taxes from their subjects. Ganda armies also seized territory held by Bunyoro, the neighboring kingdom to the west. Ganda cultural norms also prevented the establishment of a royal clan by assigning the children of the Kabaka to the clan of their mother. At the same time, this practice allowed the Kabaka to marry into any clan in the society.
One of the most powerful appointed advisers of the Kabaka was the Katikkiro, who was in charge of the kingdom's administrative and judicial systems - effectively serving as both prime minister and chief justice. The Katikkiro and other powerful ministers formed an inner circle of advisers who could summon lower-level chiefs and other appointed advisers to confer on policy matters. By the end of the nineteenth century, the Kabaka had replaced many clan heads with appointed officials and claimed the title "head of all the clans".
