Alan Brodrick, 1st Viscount Midleton, a leading Anglo-Irish lawyer and politician of the early eighteenth century, is appointed Lord Chief Justice of the Court of Queen’s Bench on December 24, 1709. He is a man of great gifts, but so hot-tempered and passionate that even Jonathan Swift is said to have been afraid of him.

Brodrick is the second son of Sir St. John Brodrick of Ballyannan, near Midleton in County Cork, by his wife Alice, daughter of Laurence Clayton of Mallow, County Cork. His father receives large land grants during The Protectorate, and thus the family has much to lose if the land issue in Ireland is settled to the satisfaction of dispossessed Roman Catholics. He is educated at Magdalen College, Oxford and the Middle Temple, being called to the English bar in 1678. He and his relatives flee Ireland during the Glorious Revolution. They are attainted under the rule of King James II in Ireland. In exile in England, Brodrick argues for a speedy reconquest.

In 1690 Brodrick returns to Dublin and is given the legal office of Third Serjeant. He also becomes Recorder of Cork. He is dismissed as Serjeant in 1692, apparently on the ground that there is no work for him to do. While complaining bitterly about his dismissal, he admits privately that his post has been a superfluous one.

As a prominent Whig supporter of the outcome of the Glorious Revolution he is not always in agreement with court policies in Ireland, which he considers too lenient on the Jacobites. The dismissal of the First Serjeant, John Osborne, at the same time as Brodrick is due to his even stronger opposition to Court policy. Despite this he often holds Irish government offices and aspires to manage the Irish Parliament for English ministers. He represents Cork City in the Irish Parliament, which meets in 1692 and holds this seat until 1710. He is a vocal opponent of court policies, until the new Whig Lord Deputy of Ireland, Lord Henry Capell, decides to appoint him Solicitor-General for Ireland in 1695. He promotes penal laws against Catholics, whilst also supporting greater powers for the Irish Parliament.

Brodrick is Speaker of the Irish House of Commons from September 21, 1703. After promoting resolutions critical of the Lord Lieutenant of Ireland he loses his post as Solicitor-General in 1704. From 1707 until 1709 he is Attorney-General for Ireland. He becomes Chief Justice of Ireland in 1710 and is replaced as Speaker on May 19, 1710, but again holds the office in the next Parliament (November 25, 1713 – August 1, 1714), where he also represents Cork County. He is appointed Lord Chancellor of Ireland in 1714 and is ennobled in the Peerage of Ireland in 1715, as the 1st Baron Brodrick. He is advanced to the rank of 1st Viscount Midleton in 1717.

Brodrick feuds with his successor as Speaker William Conolly, as they are rivals to be the leading figure in Irish politics. Despite intrigues in England, he loses out and resigns as Lord Chancellor in 1725. He leaves behind him a legacy of bitterness and ill-will for which he is not really responsible as the Irish peers choose to blame him for the loss of their powers under the Sixth of George I, rather than their own misjudgment in imprisoning the Barons of the Exchequer.
