+title: Ubuntu Imbizo Community Assembly
+description: >-
+  A Southern African community assembly rooted in the philosophy of ubuntu
+  ("I am because we are"), where community members gather to deliberate
+  matters of shared concern. Found across Nguni and other Southern African
+  societies, the imbizo is a forum for collective discussion and decision.

+steps:
+  - headline: Call the imbizo
+    description: >-
+      A senior member or chief calls the imbizo, announcing the matter and
+      inviting all adult community members to attend.
+  - headline: Open with ubuntu
+    description: >-
+      The convenor opens by affirming ubuntu — that the community is bound
+      together and that each person's dignity is tied to the others'.
+  - headline: Deliberate together
+    description: >-
+      Members speak in turn, with elders and those most affected given
+      particular attention. The convener seeks the points of agreement
+      that all can accept.
+  - headline: Decide collectively
+    description: >-
+      The decision is reached collectively, framed as the community's will
+      rather than the chief's. Dissent is acknowledged and recorded.
+  - headline: Bind the community
+    description: >-
+      The decision is pronounced in a way that affirms the ongoing
+      relationship of the community, even where some disagreed.
+outcome: >-
+  A decision is made that carries the community's collective weight,
+  grounded in the recognition that each person belongs to the others.
+practice: >-
+  Ubuntu is not a slogan but the premise — that no decision stands apart
+  from relationship. If the imbizo becomes a chief's pronouncement, the
+  form is broken.
