High King of Ireland - Later High Kings

Later High Kings

By the twelfth century the dual process of agglomeration of territory and consolidation of kingship saw the handful of remaining provincial kings abandoning the traditional royal sites for the cities, employing ministers and governors, receiving advice from an oireacht (a body of noble counsellors), presiding at reforming synods and maintaining standing armies.

Early royal succession had been by alternation between collateral branches of the wider dynasty but succession was now confined to a series of father/son, brother/brother and uncle/nephew successions within a small royal fine marked by an exclusive surname.

These compact families (O Brien of Munster, MacLochlainn of the North, O Connor of Connacht) intermarried and competed against each other on a national basis so that on the eve of the Anglo-Norman incursion of 1169 the agglomeration/consolidation process was complete and their provincial kingdoms divided, dismembered and transformed into fiefdoms held from (or in rebellion against) one of their number acting as king of Ireland.
