What is "omukama"

Omukama: often translated as "king of kings", (O)Mukama means in Bantu (Batoro-, Banyoro- and other languages) something like "superior milkman/milkbringer". The title "Omukama" is used in the region of Uganda and neighbouring countries, especially in the kingdoms of " Bunyoro" and " Toro". After reestablishing the Ugandan kingdoms in the 1990s the Omukama are nowadays accepted "kings" with a merely cultural function.
