He served as ToryMember of Parliament (MP) for Carmarthenshire, from 1820 to 1831. At the 1831 General Election he chose to stand down from the Commons on the basis that his political views diverged from those of his constituents.[1] The following years, however, he contested the seat and was re-elected, serving until his elevation to the peerage in 1852 upon the death of his father.
Rebecca Riots
When the Rebecca Riots of 1843–44 reached Carmarthenshire Rice-Trevor, as Lieutenant-Colonel Commandant of the Royal Carmarthen Fusiliers Militia, and MP and vice-lieutenant of the county, returned from London to deal with the situation. After the rioters burned crops on his father's Dinefwr estate he threatened armed retaliation. The response of the rioters was to dig a grave in the grounds and announce that Rice-Trevor would occupy it by 10 October 1843. He did not, but he did order in so many troops and police that a barracks had to be built to accommodate them.[2]
Later life
Lord Dynevor succeeded to the title of Baron Dynevor and the Dinefwr estate on the death of his father in 1852. He was an honorary colonel in the militia and from 1852 to 1869 he served as ADC to Queen Victoria.
Dynevor died on 7 October 1869, aged 74, at Malvern, Worcestershire from paralysis and was interred in the family vault at Barrington Park, the family estate in Gloucestershire.[3] As he died without male issue, his cousin the ReverendFrancis William Rice succeeded to the barony. The family wealth passed to his daughters, thus splitting the wealth from the title.
