Curzon was born at the family’s London house in Welbeck Street. Having failed responsions, he left Oxford without taking a degree and replaced his father as Member for Clitheroe on their interest at the 1831 general election, shortly after coming of age. He was an anti-reformer, with no more than a passing interest in politics, and made no reported parliamentary speeches. He divided against the Grey ministry’s reintroduced reform bill at its second reading, 6 July, voted to use the 1831 census to determine English borough disfranchisements, 19 July, and divided against Chippenham’s inclusion in schedule B, 27 July, and the bill’s passage, 21 Sept. 1831. He voted against the revised reform bill at its second and third readings, 17 Dec. 1831, 22 Mar., and in the minority of 27 for an amendment awarding certain Lincoln freeholders county votes, 23 Mar. 1832. He voted against administration on the Dublin election controversy, 23 Aug. 1831, and the Russian-Dutch loan, 26 Jan., 12 July, a division he dismissed in a sarcastic letters (of which 506 survive) to his lifelong friend Walter Sneyd, as ‘amazing sport - fun may I say’.
Devoting himself to his chief passion, collecting ancient manuscripts, particularly those of the East, on which pioneering work his fame rests, he toured Egypt, Greece, Albania, Turkey and the Holy Land in 1833-4 and 1837-8, and became one of a circle of bibliophiles cultivated by Sir Thomas Phillips, whose regular correspondent he became.
On the death of his father in 1863 he succeeded to the 50-acre Staffordshire estate of Ravenhill, but not the valuable property of Hagley, which, as his father had willed, was sold to provide an income for his younger brother. The will became a bone of contention within the family, and Curzon refused to stay at Parham with his mother, whom he accused of plundering their slender resources.
