Early life
Mansel was the second and first surviving son of Sir Edward Mansel, 4th Baronet, of Margam Abbey, Glamorgan, Wales, sometime Member of Parliament for Glamorganshire, and his wife Martha Carne. Mansel's great-grandfather was Henry Montagu, 1st Earl of Manchester. He received his BA in 1686 from Jesus College, Oxford and by 1699 he was awarded his MA from New Inn Hall, Oxford. On 18 May 1686 he married Martha Millington, daughter of Francis Millington, merchant, of London and Newick Place, Sussex.
Political career
Mansel won the Welsh seat of Cardiff as a Tory MP in the 1689 Parliamentary election. Although he held the seat until 1698, it wasn't until he won the seat of Glamorgan in 1699 that he began to gain higher political offices. In 1701 he held the office of High Sheriff of Glamorgan. In 1714 he was appointed Comptroller of the Household to Queen Anne, a position he held until 1708. Whilst Comptroller of the Household, Mansel was invested as a Privy Council.
On the death of his father on 17 November 1706, he succeeded to the baronetcy and inherited a life interest in the Briton Ferry estate. On account of the death of his father, as well as the death of his cousin Thomas Mansel II, he was largely inactive in the period 1706 to 1707. From 1710 to 1711 he was a Commissioner of the Treasury. His interests were attracted by the South Sea Company and Royal African Company.
On 1 January 1712, he was raised to the peerage as Baron Mansel of Margam, and vacated his seat in the House of Commons to sit in the House of Lords. From 1712 to 1714, he was Teller of the Exchequer and from 1714 to 1715 he was Vice-Admiral of South Wales and Governor of Milford Haven. He also held the office of Chamberlain of South Wales from circa 1714. Mansel reduced his participation in politics in 1715, with a proxy attending Parliament in his stead.
