The agreement stipulated that Kabaka should exercise direct control over the indigenous people of Buganda, who administer justice by Lukiiko and its officials.  He also consolidated the power of Bakungu`s majority-Protestant client leaders, led by Kagwa. The British sent few civil servants to run the country and relied mainly on the Bakungu chiefs. For decades, they have been privileged because of their political abilities, their Christianity, their friendly relations with the British, their ability to collect taxes and Entebbe`s proximity to Uganda`s capital. In the 1920s, British administrators were more confident and needed less military or administrative support.  Assuming that the territory of the Kingdom of Uganda, which extends within the borders mentioned in the agreement, amounts to 19,600 square miles, it is divided into the following proportions: Alfred Tucker, Bishop of East Africa and Bishop of Uganda, has asked the British authorities, at the request of Sir Gerald Portal, to take control of Uganda.  On 29 May 1893, a contract between Portal and Kabaka Mwanga secured Uganda as a British protectorate. On August 27, 1894, Mwanga was forced to sign another contract with Colonel H.E. Colvile, who favoured the conventional acquisition of the territory.  Although the treaties of 1893 and 1894 were concluded because Uganda, as defined by the Berlin Conference, stumbled upon the British sphere of influence, Britain did not have the sanctity of traditional leaders and their peoples.
It was important that an agreement be reached, contrary to a treaty, so that British domination would become de jure and not de facto.  The agreement was negotiated by Alfred Tucker, Bishop of Uganda, and signed among others by Mr. Katikiro Apollo Kagwa, on behalf of Kabaka (Daudi Cwa II), then a young child, and Sir Harry Johnston on behalf of the British colonial government. On Tuesday, March 10, the 120th anniversary of the kingdom of Buganda, under kabaka (king) Daudi Chwa, jumped to bed with the British. The signing of the agreement not only took away the rights of the kingdom, but paved the way for the tutelage and plundering of other parts of Uganda. The agreement anchored British rule in Buganda and also gave the Baganda the opportunity to extend their influence to other parts of the country. Territories that were not under the kingdoms were taken over by Buganda`s neocolonial agents such as Semei Kakungulu. Before the Buganda Agreement of 1900, the Kingdom of Buganda was an absolute monarchy ruled by Kabaka.
At that time, there were three categories of kabaka, 1.Chiefs who were also called Bakungu or heads of administration, these were appointed by Kabaka, 2. the traditional Bataka leaders plus the Batangole chiefs, who served as representatives of the king, they were responsible for the surveillance of the royal lands, the maintenance of internal security in the kingdom as well as military tasks. The Uganda Agreement of March 1900 (alternatively the Mengo Treaty) formalized relations between the Kingdom of Uganda and the British protectorate of Uganda.  It was amended by the Buganda Convention of 1955 and the Buganda Convention of 1961. Made in English and Luganda in Mengo, Kingdom of Uganda, March 10, 1900. However, with the signing of the 1900 Agreement, land was allocated to Kabaka, its family members and its leaders, as civil servants and also as individuals. The land issue was addressed in Article 15, which estimated the total area of land in Buganda at 19,600 square miles. But the agreement also stipulated that if a survey were to be conducted, and it was found that Buganda had less than 19,600 square miles, “then the part of the country that must be entrusted to Her Majesty`s Government will be reduced to the extent by the lack found in the estimated area.” After the agreement came into force, the country was divided in Buganda to Mailo and Kronland.
