Lord President of Munster: The post of Lord President of Munster was the most important office in the English government of the Irish province of Munster from its introduction in the Elizabethan era for a century, to 1672, a period including the Desmond Rebellions in Munster, the Nine Years' War, and the Irish Rebellion of 1641.  The Lord President was subject to the chief governor, but had full authority within the province, extending to civil, criminal and church legal matters, the imposition of martial law, official appointments, and command of military forces.  Some appointments to military governor of Munster were not accompanied by the status of President.  The width of his powers led to frequent clashes with the longer established courts, and in 1622 he was warned sharply not to "intermeddle" with cases which were properly the business of those courts.  He was assisted by a Council whose members included the Chief Justice of Munster, another justice and the Attorney General for the Province.  By 1620 his council was permanently based in Limerick.

The office was created in 1569, and in 1604 was reconstituted with full powers to hear all civil suits, to impose martial law and to proceed with "fire and sword" against the King's enemies.  The width of his powers gave rise to clashes with the longer established courts: in 1622 he and the Lord President of Munster were ordered not to "intermeddle' in cases which were properly within the remit of those courts.  He was assisted by a council whose members included the Chief Justice of Connacht, one or two associate justices and the Attorney General for the Province.  The office was abolished in 1672.
