Thomas Belasyse, 1st Viscount Fauconberg

Thomas Belasyse, 1st Viscount Fauconberg (1577 – 18 April 1653), styled Baron Fauconberg between 1627 and 1643 and Sir Thomas Belasyse, 2nd Baronet between 1624 and 1627, was an English politician who sat in the House of Commons at various times between 1597 and 1624 and was raised to the peerage in 1627. He was an ardent supporter of the Royalist cause in the English Civil War.

Before the Civil War, Belasyse and his family had a long running confrontation with Sir Thomas Wentworth, a close advisor to King Charles I, primarily over local government issues in Yorkshire. This confrontation did not shake Belasyse's support for the monarchy and before and during the Civil War, he and his son Henry, were ardent supporters of the Royalist cause. Charles honoured Belasye in appreciation, but towards the end of the First Civil War, Belasye was forced to flee abroad. While he was in exile his estates were sequestered by Parliament because he was a known "delinquent", and on his return to England and as he refused to swear to the oath of abjuration he was convicted of recusancy.

Biography Belasyse was educated at Jesus College, Cambridge in the early 1590s. He had Roman Catholic leanings, and married into a known recusant family, but stayed within the laws of the time and attended Anglican Church services. He entered Parliament in 1597 when he was elected to represent Thirsk, a seat his father had held, in the second from last Elizabethan parliament. He was knighted by James I and served as a justice of the peace in the North Riding. He remained active in national politics and represented Thirsk again in the 1614, 1621, and 1624 parliaments of James I.

During the early years of the reign of Charles I the Belasyse family sided with Sir John Savile, the custos rotulorum of the West Riding, against Sir Thomas Wentworth. The Savile's allied themselves with the Duke of Buckingham and it may have been through this political connection that on 25 May 1627 that Belasyse was raised to the peerage as Lord Fauconberg of Yarm.

After the assassination of Buckingham, Wentworth's influence at court grew and with it his power, while that of his political opponents Yorkshire waned. After Wentworths's appointment as president of the council of the north in 1628, Fauconberg and his son Henry were briefly imprisoned and they opposed the style of government that Wentworth's influence at court helped to foster. Henry Belasyse (1604–1647) John Belasyse, 1st Baron Belasyse Mary (1606–25) married John, lord Darcy of Darcy (c1579-1635) in 1624.
