Rowland FitzEustace, 1st Baron Portlester

Rowland FitzEustace, 1st Baron Portlester ( born about 1430; died 19 December 1496) was an Irish peer, statesman and judge. He was one of the dominant political figures in late fifteenth-century Ireland, rivalled in influence only by his son-in-law, the 8th or "Great" Earl of Kildare.

FitzEustace was the eldest son of Sir Edward FitzEustace of Castlemartin, County Kildare, Lord Deputy of Ireland, and his wife Alicia. He belonged to one of the most prominent of the "Old English" families of the Pale. He was called to the Bar in England in about 1454, and soon afterwards became Chief Clerk to the Court of King's Bench (Ireland). He was appointed Lord Chancellor of Ireland and Lord Treasurer of Ireland by King Edward IV of England in 1474 and was elevated to the Irish peerage as Baron Portlester in 1462. In the latter year he was accused of treason, but defended himself with such vigour that the charges were dropped: similar charges made against him in 1470 were not pursued. In 1474 he was a founder member of the Brotherhood of Saint George, a short -lived military order charged with the defence of the Pale, the only part of Ireland which was under secure English rule.

In 1478 when his son-in-law, Gerald FitzGerald, 8th Earl of Kildare was replaced as Lord Deputy of Ireland by Lord Grey, Portlester organised a campaign of non-cooperation with the new Deputy. When Grey ordered him to hand over the Great Seal of Ireland, Portlester refused point blank, thus making the conduct of official business impossible. The King went to considerable lengths to support Grey. He ordered Thomas Archbold, the Master of the Royal Mint in Ireland, to strike a new Great Seal, declaring that the Seal held by Portlester was annulled, and that all acts passed under it were utterly void; but these efforts were no avail. So effective was the campaign of obstruction that after a few months Lord Grey was forced to return to England. Portlester was reappointed Chancellor by Henry VII, but removed because of his part in the crowning of the pretender, Lambert Simnel, as King Edward VI of England, on May 24, 1487. This coronation took place in Christ Church Cathedral, Dublin, Ireland. Nearly every noble and Prince in Ireland took part in the ceremony. Simnel invaded England with an Irish army which was crushed at the Battle of Stoke. Henry VII was magnanimous in victory, sparing Simnel's life and issuing pardons to Portlester and his fellow peers; but he decided to split the offices held by Lord Portlester between Alexander Plunket and Sir James Ormond. Portlester nonetheless remained an influential figure for the remaining decade of his life, and was able to fight off an attack on his record as Treasurer in 1493.
