By establishing Uganda`s northern border as the Kafu River, the Colvile Agreement of 1894 formalized that Uganda would obtain certain areas in exchange for their support against Bunyoro.  Two of the „lost counties” (Buyaga and Bugangaizi) were returned to Bunyoro after the referendum on lost counties in Uganda in 1964.  In English and Luganda in Mengo, Uganda, on 10 March 1900. Before the signing of the agreement, the whole country in Buganda belonged to Kabaka, hence the title of Sabataka. 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. Daudi Chwa, who was a minor at the signing of the agreement, said that at the age of majority, he said that British control had watered down his authority. My current position is so early that I am no longer the direct leader of my people. I am regarded by my subjects only as one of the paid British servants. This is because I don`t really have power over my people, not even the smallest leader,” Chwa said after Baganda and the British domination of Low and Pratt in 1900-1995. Every order given, whether by my local leader or by the Lukiiko himself, is always regarded with contempt, unless confirmed by the district commissioner. Chwa`s oath showed how enslaved Buganda had been. The three regents – Sir Apollo Kaggwa, Zakaria Kisingiri and Stanislas Mugwanya – then signed on behalf of Chwa, while Sir Harry Johnson signed on behalf of King Edward VII.
In accordance with Article 6 of the agreement, Kabakaship ceded its authority and power to the colonialists. As long as Kabaka, the chiefs and the people of Uganda comply with the laws and regulations established for their organization and management of the Kingdom of Uganda in question, Her Majesty`s Government agrees to recognize Kabaka as the indigenous ruler of Buganda province under the protection and rule of Her Majesty,” Article 6 of the agreement states. 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. Mailo Land belonged to the von Buganda government and its officials, while the Crown belonged to the protectorate government. The signing, in 1900, took place after years of negotiations under the leadership of Bishop Alfred Tucker. It is not surprising that the Anglican Church, under the missionary society of the Church, took the lion`s share in the new administration after the signing of the Agreement. The agreement had three sections: power-sharing, the public finance system and the country. But there were difficulties because Kabaka Chwa was only a minor who was not involved in the negotiations. Assuming that the territory of the Kingdom of Uganda, which consists within the borders mentioned in the agreement, amounts to 19,600 square miles, it is divided into the following proportions: unlike the treaties of 1893 and 1894, the Ugandan convention of 1900 included clear borders of the Kingdom of Uganda, a land ownership system and a tax policy.
 The country of Mailo was subdivided between members of the royal family, Reich officials and a few individuals.
