outside the UPC (including KY supporters), this was a sign that Obote was vulnerable. Keen observers realised the UPC was not a cohesive unit. The collapse of the UPC-KY alliance openly revealed the dissatisfaction Obote and others had about Buganda's "special status". In 1964, the government responded to demands from some parts of the vast Buganda Kingdom that they were not the Kabaka's subjects. Prior to colonial rule, Buganda had been rivalled by the neighbouring Bunyoro kingdom. Buganda had conquered parts of Bunyoro and the British colonialists had formalised this in the Buganda Agreements. Known as the "lost counties", the people in these areas wished to revert to being part of Bunyoro. Obote decided to allow a referendum, which angered the Kabaka and most of the rest of Buganda. The residents of the counties voted to return to Bunyoro despite the Kabaka's attempts to influence the vote. Having lost the referendum, KY opposed the bill to pass the counties to Bunyoro, thus ending the alliance with the UPC. The tribal nature of Ugandan politics was also manifesting itself in government. The UPC which had previously been a national party began to break along tribal lines when Ibingira challenged Obote in the UPC. The "North/South" ethnic divide that had been evident in economic and social spheres now entrenched itself in politics. Obote surrounded himself with mainly northern politicians – A. A. Neykon, Felix Onama, Alex Ojera – while Ibingira's supporters who were subsequently arrested and jailed with him, were mainly from the South – George Magezi, B. Kirya, Matthias Ngobi. In time, the two factions acquired ethnic labels – "Bantu" (the mainly Southern Ibingira faction) and "Nilotic" (the mainly Northern Obote faction). The perception that the government was at war with the Bantu was further enhanced when Obote arrested and imprisoned the mainly Bantu ministers who backed Ibingira. These labels brought into the mix two very powerful influences. First Buganda – the people of Buganda are Bantu and therefore naturally aligned to the Ibingira faction. The Ibingira faction further advanced this alliance by accusing Obote of wanting to overthrow the Kabaka. They were now aligned to opposing Obote. Second – the security forces – the British colonialists had recruited the army and police almost exclusively from Northern Uganda due to their perceived suitability for these roles. At independence, the army and police was dominated by northern tribes – mainly Nilotic. They
