James Mann, 5th Earl Cornwallis

James Mann, 5th Earl Cornwallis (20 September 1778 – 21 May 1852), known as James Cornwallis until 1814 and as James Mann between 1814 and 1823 and styled Viscount Brome between 1823 and 1824, was a British peer and Tory politician.

Background and education Born James Cornwallis, he was the only son of the Right Reverend James Cornwallis, 4th Earl Cornwallis, Bishop of Lichfield and Coventry, by Catherine, third daughter of Galfridus Mann, of Boughton Place, Boughton Malherbe, Kent, and sister of Sir Horatio Mann, 2nd Baronet. Charles Cornwallis, 1st Marquess Cornwallis, and Sir William Cornwallis were his uncles. He was educated at Eton and St John's College, Cambridge, where he received his M.A. in 1798.

Political career Cornwallis was returned to parliament as one of two representatives for Eye in 1798 (alongside his uncle Sir William Cornwallis), a seat he held until November 1806. He was re-elected for the same constituency again in January 1807, but this time only held the seat until May of the same year. After succeeding to the estates of his maternal uncle in 1814, he assumed by Royal licence the surname of Mann in lieu of Cornwallis. He became known by the courtesy title Viscount Brome in 1823 after his father succeeded in the earldom of Cornwallis. In the following year, he himself succeeded in the earldom and took his seat in the House of Lords. The Cornwallis title was revived in 1927 when Fiennes's son and namesake Fiennes Cornwallis was made Baron Cornwallis.
