Organization Nkore society evolved into a system of ranked statuses, where even among the cattle-owning elite, patron-client ties were important in maintaining social order. Men gave cattle to the king (
mugabe) to demonstrate their loyalty and to mark life-cycle changes or victories in
cattle raiding. This loyalty was often tested by the king's demands for cattle or for military service. The reign of Ntare V is full of examples of famous Bairu
emitwe leaders, such as Ruhara, who was also a regional chief. Ruharu was a close friend of King Ntare V. He gained great fame and renown because of the leading part he played in conquering large parts of Rwampara County, which was previously part of the
Mpororo kingdom. Ruhara, together with other Iru such as Koyokoma and Rwankwiiziire, played the leading role in traveling across Nkore to stop the flow of people fleeing Nkore after the death of Ntare V, showing their great influence and personal standing in the society.
Iru and Hima relations Nkore society was composed of the Iru (pl. Bairu) and Hima (pl. Bahima). The Iru were cultivators who had some cattle while the Hima were those engaged almost exclusively in pastoralism (often having herds in the many dozens or even hundreds). The Bairu and Bahima did not have many opportunities to mix much due to the simple fact that they had different lifestyles which did not give them much time left for communal leisure gatherings. The Bairu engaged in the cultivation of finger millet like, the building of homesteads, brewing beer, and the hunting of wild game for meat, which the Bahima (except for beer drinking did not engage in. The Hima settled a specific region of marshlands which was mostly devoid of population, with only a few scattered agriculturalists living there. There were virtually no contacts between the two groups. In Nkore, it was believed that that "obwiru" [the state of being a Mwiru] was poverty; he who was poor was a Mwiru; he who was rich was a Muhima. Marko Kiiza of the
Kingdom of Igara says: A number of social pressures worked to destroy Hima domination of Nkore. ==Military==
