The Story

5 Chapters · This narrative combines documented history with dramatized scenes for storytelling purposes.

Governance

Government Type
Tribal Confederation
Notable Dynasty
While some families, such as the Arverni or the Eóganachta in later Irish tradition, established hereditary claims to leadership, there was no single dynasty or ruling house that dominated the entire Celtic world. Leadership was contested and could be transferred through election, combat, or negotiation.
Political System
The Celts organized themselves into numerous tribes, each led by its own chieftain or king. These tribes often formed loose confederations for mutual defense or economic advantage, but there was no unified central authority across the Celtic world. Political power was deeply rooted in kinship networks, warrior aristocracies, and the influence of religious specialists, especially the druids.
