A clan represents a group of people who can trace their lineage to a common ancestor in some distant past. In the customs of Buganda, lineage is passed down along patrilineal lines.
The clan essentially forms a large extended family and all members of a given clan regard each other as brothers and sisters regardless of how far removed from one another in terms of actual blood ties.
Normally a clan is associated with an Animal, Bird, Plant or other Symbol. The Clans are subdivided into small cultural and administrative units with the Kabaka as the head.
