Chief governor of Ireland

The chief governor was the senior official in the Dublin Castle administration, which maintained English and British rule in Ireland from the 1170s to 1922. The chief governor was the viceroy of the English monarch (and later the British monarch) and presided over the Privy Council of Ireland. In some periods he was in effective charge of the administration, subject only to the monarch in England; in others he was a figurehead and power was wielded by others.
