Admin HistoryWilliam Henry Cavendish Bentinck, 3rd Duke of Portland (1738-1809) was a leading politician and statesman throughout the second half of the 18th century, whose life was entirely dominated by his political career. He was elected M.P. for Weobly, Herefordshire in 1761, but took his seat in the House of Lords when he inherited the title from his father in 1762. From then until his resignation as Prime Minister in 1809 he held enormous political influence. He was Lord Lieutenant of Ireland, 1783, Home Secretary, 1794-1801 and served twice as Prime Minister.
Custodial HistoryThese papers form a sub-group of the Portland (Welbeck) Collection (Pw) and were part of the first deposit received from Welbeck Abbey in 1949 from the 7th Duke of Portland.
DescriptionThe correspondence with leading political figures touches on all the major issues of his time, including the American War of Independence and the Irish Act of Union. Many relatives, friends and even strangers sought his support and patronage and their letters help to demonstrate the network of influence he controlled. Correspondence with political figures reflects his Whig connections and there is much concerning his acrimonious dispute with Sir James Lowther in Cumberland.

There is a considerable quantity of correspondence relating to the running of the various estates owned by the duke and his mother, Margaret, the 2nd Duchess. It reflects their difficult financial situation, and developments in agricultural and horticultural practices. He maintained a close relationship with family members including his mother and father, sisters (Elizabeth Thynne, Marchioness of Bath, and Henrietta Grey, Countess of Stamford), his younger brother (Lord Edward Bentinck), his wife (Lady Dorothy Cavendish) and various members of the Dutch Bentinck family. Correspondence with friends, notably George Byng (4th Viscount Torrington), Sir Richard Kaye and Baron Beaumont Hotham, is also present.

The miscellaneous papers include some correspondence and estate papers. Election matters are well represented, especially the Cumberland dispute with Sir James Lowther. There are also papers relating to the affairs of the East India Company and letters on foreign intelligence. Included in the miscellaneous section is the large collection of letters in French from Countess Charlotte Sophie Bentinck (1715-1800) to her grand-daughter, Lady Sophie Hawkins Whitshed, which cover both Bentinck family matters and the political and diplomatic developments in Europe in the years leading up to and during the French Revolution.
