+title: Zulu Imbizo Royal Assembly
+description: >-
+  A Zulu practice in which a king or senior chief calls an imbizo — a
+  gathering of all men of the nation or region — to hear matters and
+  receive instruction. Distinguished from the smaller indaba, the imbizo
+  is a mass assembly for matters of national importance.

+steps:
+  - headline: Call the imbizo
+    description: >-
+      The king or chief calls the imbizo, with the call going out through
+      the regions. All men of the affected area are expected to attend.
+  - headline: Gather at the royal grounds
+    description: >-
+      The men gather at the royal grounds, seated by regiment and region.
+      The king or his representative opens the proceedings.
+  - headline: Present the matter
+    description: >-
+      The matter — a threat, a policy, a celebration — is presented. Those
+      gathered may speak, with senior men and regiment leaders heard first.
+  - headline: The king pronounces
+    description: >-
+      The king or his representative pronounces the decision or position,
+      framed as the will of the nation gathered. The assembly affirms by
+      presence and ululation.
+outcome: >-
+  A matter of national importance is addressed with the whole community
+  present, giving the decision the weight of the assembled nation.
+practice: >-
+  The imbizo is distinct from the indaba — it is a mass assembly, not a
+  leaders' discussion. The king's pronouncement carries the legitimacy of
+  the gathering; without the gathering, it would not.
