Tooro was founded in 1830 when a Prince of Bunyoro rebelled and established his own independent kingdom. It was incorporated back into Bunyoro in 1876, but later it reasserted its independence in 1891. The Kingdom of Toro also names its King “Omukama” and the current holder of the title is Rukidi IV.
Like Buganda, Bunyoro, Ankole and Busoga, Toro’s monarchy was abolished in 1967 by the government of Uganda, but was reinstated in 1993, at which time its borders receded from its historical boundaries that went to the borders of Uganda, possibly to avoid any conflict that could occur with a region even partially autonomous having control over the national borders.
