Biography of Henry Pelham-Clinton, 4th Duke of Newcastle under Lyne (1785-1851)

After succeeding to his dukedom in 1795, at the relatively tender age of ten, the 4th Duke was educated at Eton but refrained from pursuing his studies further at university. Instead, in 1803, encouraged by the Peace of Amiens which provided a break in hostilities with France, his mother and stepfather took him on a European Tour. Unfortunately, war broke out once again, and the young duke was detained at Tours in 1803, where he remained until 1806.

The 4th Duke was appointed to the usual offices for a man of his position - including Lord Lieutenant of Nottinghamshire and Steward of Sherwood Forest and Folewood Park. Unlike other members of his family, he did not hold any national office, but he was extremely active in politics, both on the local and national stage.

From 1846 he became one of the leaders of the so-called Tory 'Ultras', staunchly supporting the traditional establishment of Church, Country and State. He was a vehement opponent of policies such as Catholic Emancipation, and also of electoral reform. This stance led to attacks on his property during the Reform Bill Riots of 1831. Nottingham Castle was burnt to the ground and his residences at Clumber, Nottinghamshire and Portman Square, London, also had to be fortified against the mob.

The duke's opinions were not altered, however. He had been used to exercising his political influence in areas where he was the major landholder, and complained bitterly that the Reform Bill had lost him the patronage and influence of six boroughs - including Aldborough, Yorkshire and Newark, Nottinghamshire - at a cost of around £200,000.

When he reached his age of majority, the 4th Duke succeeded to his vast family estates, mostly centred around Nottinghamshire, though his management of the estate was constrained by the provisions of his grandfather's will - originally designed to prevent his father and mother from controlling the estate. His marriage brought further Nottinghamshire properties into the family as well as considerable wealth.

Family was a central feature of the 4th Duke's life. He had a strained relationship with his mother, and was devastated by the early loss of his wife following a difficult childbirth in 1822. Left to bring up a young family alone, he strove to do his best for his young brood - though his methods were not always approved of. He sadly ended his life estranged from most of his children, particularly his heir, the 5th Duke.
