Richard Boyle, 1st Earl of Cork, English-born politician who serves as Lord Treasurer of the Kingdom of Ireland and is also known as the Great Earl of Cork, dies on September 15, 1643 in Youghal, County Cork. He is an important figure in the continuing English colonisation of Ireland in the 16th and 17th centuries, as he acquires large tracts of land in plantations in Munster in southern Ireland.

Boyle is born at Canterbury, Kent, England on October 3, 1566, the second son of Roger Boyle, a descendant of an ancient landed Herefordshire family, and of Joan, daughter of John Naylor. He goes to The King’s School, Canterbury, at the same time as Christopher Marlowe. His university education begins at Corpus Christi College, Cambridge, England, in 1583. After this he studies law at the Middle Temple in London and becomes a clerk to Sir Roger Manwood, who is then Chief Baron of the Exchequer.

Boyle goes to Ireland in 1588. He becomes deputy Escheator under Ireland’s Escheator General John Crofton and uses his office to enrich himself, only to lose his property in the Munster rebellion in 1598. Returning to England, he is imprisoned on charges of embezzlement arising from his activities in Ireland. He is acquitted by a royal court, however, and in 1600 Elizabeth I of England appoints him clerk of the council of Munster.

Two years later, Boyle purchases Sir Walter Raleigh’s estates in the Irish counties of Cork, Waterford, and Tipperary. By employing settlers imported from England, he develops his lands and founds ironworks and other industries. The enormous wealth he accumulates brings him honours and political influence. Created Earl of Cork in 1620, he is appointed a Lord Justice of Appeal in 1629 and Lord High Treasurer in 1631. Nevertheless, soon after Sir Thomas Wentworth (afterward Earl of Strafford) goes to Ireland as lord deputy in 1633, Boyle is fined heavily for possessing defective titles to some of his estates. Thereafter his political influence declines.

Boyle dies at Youghal on September 15, 1643, having been chased off his lands in the Irish Rebellion of 1641. His sons, however, recover the family estates after the suppression of the rebellion.

Boyle’s first wife, Joan Apsley, the daughter and co-heiress of William Apsley of Limerick, whom he marries on November 6, 1595, dies at Mallow, County Cork on December 14, 1599 during childbirth. By his second wife, Catherine Fenton, daughter of Sir Geoffrey Fenton, he has eight daughters and seven sons, including the renowned chemist Robert Boyle and the statesman-dramatist Roger Boyle, 1st Earl of Orrery.
