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.
