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 Lord Deputy of Ireland, 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.[1] 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 the President, Donogh O'Brien, 4th Earl of Thomond, 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 post was suppressed in 1672.
