Mwanga came to the throne at the age of 16. He increasingly regarded the greatest threat to his rule coming from the Christianmissionaries who had gradually penetrated Buganda. His father had played-off the three religions, Catholics, Protestants and Muslims, against each other and thus balanced the influence of the European colonial powers that were backing each group in order to extend their reach into Africa. Mwanga II took a much more aggressive approach, expelling missionaries and insisting that Christian converts abandon their faith or face death. A year after becoming king he executed Yusufu Rugarama, Makko Kakumba, and Nuuwa Sserwanga, who had converted to Christianity. On 29 October 1885, he had the incoming archbishop James Hannington assassinated on the eastern border of his kingdom. For Mwanga, the ultimate humiliation was the insolence he received from the pages of his harem when they resisted his sexual advances. According to old tradition the king was the centre of power and authority, and he could dispense with any life as he felt. It was unheard of for mere pages to reject the wishes of a king. Given those conflicting values Mwanga was determined to rid his kingdom of the new teaching and its followers. Mwanga therefore precipitated a showdown in May 1886 by ordering converts in his court to choose between their new faith and complete obedience to his orders and kingdom. It is believed that at least 30 Catholic and Protestant neophytes went to their deaths. Twenty-two of the men, who had converted to Catholicism, were burned alive at Namugongo in 1886 and later became known as the Uganda Martyrs. Among those executed were two Christians who held the court position of Master of the Pages, Joseph Mukasa Balikuddembe and Charles Lwanga. They had repeatedly defied the king by rescuing royal pages in their care from sexual exploitation by Mwanga which they believed contrary to Christian teaching. These murders and Mwanga's continued resistance alarmed the British, who backed a rebellion by Christian and Muslim groups who supported Mwanga's half brother and defeated Mwanga at Mengo in 1888. Mwanga's brother, Kiweewa Nnyonyintono, was elevated to the throne. He lasted exactly one month and was replaced on the throne by another brother, Kabaka Kalema Muguluma. However, Mwanga escaped and negotiated with the British. In exchange for handing over some of his sovereignty to the British East Africa Company, the British changed their backing to Mwanga, who swiftly removed Kalema from the throne in 1889. He later converted to Christianity and was baptised.
Final years
On 26 December 1890, Mwanga signed a treaty with Lord Lugard, granting certain powers over revenue, trade and the administration of justice to the Imperial British East Africa Company. These powers were transferred to the crown on 1 April 1893. On 27 August 1894, Mwanga accepted for Buganda to become a Protectorate. However, on 6 July 1897 he declared war on the British and launched an attack but was defeated on 20 July 1897, in Buddu. He fled into German East Africa, where he was arrested and interned at Bukoba. He was deposed on 9 August 1897. Tenacious as he was, he escaped and returned to Buganda with a rebel army, but was again defeated on 15 January 1898. He was captured and in April 1899 was exiled to the Seychelles. While in exile, he was received into the Anglican Church and was baptized with the name of Danieri. He spent the rest of his life in exile. He died in the Seychelles on 8 May 1903, aged 34 or 35. On 2 August 1910, his remains were repatriated and buried at Kasubi.

Quotes
"I do not want to give them my land. I want all Europeans of all nations to come to Buganda, to build and to trade as they like."
Mwanga's message to Euan Smith, British Consul in Zanzibar, 1890
"I am Mutesa's son, and what Mutesa was in Buganda that I will also be, and against those who will not have it so I shall make war."
Mwanga to Karl Peters, 1890
Quotes about Mwanga II
"... there was, however, much good feeling and even tenderness in his character when he could be kept from bad habits and was free from evil influences."
"Mwanga fought to free himself and his country of the intruders for all his reign. He did not like or want them; he was impressed by their power, but not interested in their ideas. He could not recover the old way of life nor adapt himself to the new, and in his perplexed and unhappy groping in the gap between he seems to me to deserve some sympathy."
"Mwanga... was demonstrably unequal to the task of controlling the foreigners who were subverting his kingdom under his very nose. he did not have the experience or the prestige that had enabled his father to keep foreigners in their place within his kingdom."
"Mwanga was quite right to seek to be the master in his own kingdom just as his forefathers had been, all his excesses and fault of character notwithstanding. Some of his predecessors had been guilty of worse acts of cruelty and injustice and nothing drastic had befallen them. In other words even if all the charges levelled against Mwanga by his numerous Christian and Muslim detractors were true, he was still right to claim supreme authority in the kingdom of his forefathers."
