In a region where rainfall decides whether people eat, responsibility for rain is a political office. Who holds it, what it obliges them to do, and why it is a burden rather than a privilege.
Rainfall in the Lower Omo is unreliable, and the difference between rain and no rain is the difference between a harvest and hunger. It follows that responsibility for rain is one of the most consequential roles a society can assign — and across the valley it is assigned to particular lineages, not to anyone who claims it.
The office, not the trick
Who holds it
Mursi and Suri — the komoru
Among the Mursi and Suri, priestly authority is vested in particular lineages, the holder often referred to as komoru. The office is inherited, associated with rain and with the wellbeing of cattle and people, and carries heavy obligation rather than personal command. In societies without chiefs, this is one of the few genuinely hereditary positions.
Konso — the poqalla
The Konso vest ritual authority in hereditary priestly lineages responsible for fertility, rain and the wellbeing of the land, within a hierarchical, terrace-farming society organised into walled towns and generation grades. The contrast with the pastoralists is instructive: the same kind of responsibility, embedded in a very different political order.
Arbore — ritual leadership and peace
Among the Arbore, hereditary ritual leaders' blessing bears on rain, fertility and above all peace. For a small people positioned between stronger neighbours, the ability to bless, to curse and to mediate is a practical instrument of survival — conflict is understood as ritually polluting, not merely dangerous.
Hamar cluster
Among the Hamar, Banna and Bashada, authority to bless is distributed by seniority rather than concentrated in a single named rain office; see blessing, curse and misfortune.
Why it is a burden
Rain, cattle and the calendar
Rain sets the ceremonial year in motion: planting, the movement of herds, the timing of initiations and new-year observances such as the Bodi Ka'el. Because cattle, rain and fertility are understood as one connected condition, a rain office is never only about weather — it sits at the centre of the whole system described in cattle, land, rain and ancestors.
What we still need
Verified terms and glosses for each office, community review of how these roles should be described, and firsthand observation of what the obligations actually involve today — including how the office has fared under state administration and religious change.
