Henry Pelham-Clinton, 5th Duke of Newcastle

Henry Pelham Fiennes Pelham-Clinton, 5th Duke of Newcastle-under-Lyne, (22 May 181118 October 1864), styled Earl of Lincoln before 1851, was a British politician and aristocrat. He sat in Parliament for South Nottinghamshire (1832–46) and for Falkirk Burghs (1846–51) until inheriting the dukedom.

Newcastle held several key offices in the mid-19th century, including Chief Secretary for Ireland, Secretary of State for the Colonies, and Secretary of State for War and the Colonies. In 1855, he resigned as Secretary of State for War owing to disastrous casualties during the Crimean War.

Background Newcastle was the son of Henry Pelham-Clinton, 4th Duke of Newcastle-under-Lyne, by his wife Georgiana Elizabeth, daughter of Edward Miller-Mundy. He was educated at Eton and Christ Church, Oxford, where he took his B.A. degree in 1832, and was created a D.C.L. in 1863.

Political career Newcastle was returned to Parliament for South Nottinghamshire in 1832, a seat he held until 1846, and then represented Falkirk Burghs until 1851, when he succeeded his father in the dukedom. Initially a Tory, he served under Sir Robert Peel as First Commissioner of Woods and Forests from 1841 to 1846 and as Chief Secretary for Ireland in 1846, as the effects of the Great Irish Famine began to take hold. He was admitted to the British Privy Council in 1841, and to the Irish Privy Council on 14 February 1846.

Newcastle joined the Peelites in 1846, and held office in Lord Aberdeen's coalition government as Secretary of State for War and the Colonies between 1852 and 1854, and as Secretary of State for War and Secretary at War between 12 June 1854 and 1 February 1855, when he resigned over the Crimean War.

From 18 June 1859 to April 1864, he served as Secretary of State for the Colonies in Lord Palmerston's Liberal administration. In 1860, while holding this office, he went to Canada and the United States, in company with the Prince of Wales. Apart from his political career he also held the honorary posts of Lord Lieutenant of Nottinghamshire from 1857 to 1864 and Lord Warden of the Stannaries from 1862 to 1864. He was made a Knight of the Garter on 17 December 1860.

Lord Lincoln was a member of the Canterbury Association from 27 March 1848. Upon succeeding to the dukedom, he joined the association's management committee on 29 January 1851. In 1849, the chief surveyor of the Canterbury Association, Joseph Thomas, named the future town of Lincoln in New Zealand after him. The town's university was in turn also named after Lord Lincoln.
