The Battle

History & Significance

Cerialis established the civitas capital of the Brigantes at Isurium Brigantum (Aldborough), a key step in converting military conquest into civilian administration. The choice of site in the Vale of York rather than at York itself showed Roman urban planning sensitivity — the military fortress and the tribal capital were kept separate as policy.
