William Cavendish-Bentinck may refer to:
Lieutenant-General Lord William Henry Cavendish-Bentinck GCB GCH PC (14 September 1774 – 17 June 1839), known as Lord William Bentinck, was a British soldier and statesman. He served as Governor-General of India from 1828 to 1835.
Bentinck was born in Buckinghamshire, the second son of Prime Minister William Bentinck, 3rd Duke of Portland, and Lady Dorothy, only daughter of William Cavendish, 4th Duke of Devonshire. Upon the third duke's marriage to Lady Dorothy, he changed the family name to Cavendish-Bentinck.
Bentinck joined the Coldstream Guards on 28 January 1791 at the age of 16, purchasing an ensign's commission. He was promoted to captain-lieutenant (lieutenant) in the 2nd Regiment of Dragoons on 4 August 1792, and to captain in the 11th Regiment of Light Dragoons on 6 April 1793. He was promoted to major in the 28th Foot on 29 March 1794 and to lieutenant-colonel in the 24th Dragoons that July. On 9 January 1798, Bentinck was promoted to colonel. In 1803 he was, to some surprise, appointed Governor of Madras, and was promoted to major-general on 1 January 1805. Although his tenure was moderately successful, it was brought to an end by a mutiny at Vellore in 1806, prompted by Bentinck's order that the native troops be forbidden to wear their traditional attire. Only after serious violence was order restored and the offending policy rescinded, and Bentinck was recalled in 1807.
Earl of Portland is a title that has been created twice in the Peerage of England, first in 1633 and again in 1689. The title Duke of Portland was created in 1716 but became extinct in 1990 upon the death of the ninth Duke.
The title of Earl of Portland was first created for the politician Richard Weston, 1st Baron Weston, in 1633. He was Chancellor of the Exchequer from 1621 to 1628 and Lord High Treasurer from 1628 to 1635, and had already been created Baron Weston, of Neyland in the County of Suffolk, in 1628. This title was also in the Peerage of England. He was succeeded by his son, the second Earl. He served as Joint Lord Lieutenant of Hampshire. His son, the third Earl, was killed at the Battle of Lowestoft in 1665. He was unmarried and was succeeded by his uncle, the fourth Earl. He was childless and on his death in 1688 the titles became extinct.
The title was created for a second time in 1689 in favour of William Bentinck, the Dutch favourite and close advisor of King William III. He was made Baron Cirencester and Viscount Woodstock at the same time he was given the earldom, also in the Peerage of England. He was succeeded in 1709 by his son from his first marriage, Henry, the second Earl of Portland. He represented Southampton and Hampshire in the House of Commons. In 1716 he was created Marquess of Titchfield and Duke of Portland in the Peerage of Great Britain. His grandson, William Cavendish-Bentinck, 3rd Duke of Portland was a noted politician. He was Prime Minister in 1783 and from 1807 to 1809 and also served as Home Secretary and as Lord President of the Council. In 1801 he assumed by Royal license the additional surname of Cavendish. Portland was the husband of Lady Dorothy Cavendish, daughter of William Cavendish, 4th Duke of Devonshire, and was a descendant on his mother's side of Henry Cavendish, 2nd Duke of Newcastle-upon-Tyne.
The Duke of Portland was a 523 ton sailing ship built in 1790 at Bordeaux, France.
Under the command of John Spence, she sailed from England in 1807, with 189 male convicts. She arrived at Port Jackson on 27 July. No convicts died on the voyage. Duke of Portland left Port Jackson on 10 November bound for England.
Duke of Portland was an American whaler of 400 tons.
She was registered in Boston, USA and left Norfolk Island in June 1802. At some stage during that month it was wrecked at Tongatapu, Tonga. All the crew were killed by natives except for one woman, Elizabeth Morley, who was rescued by the ship Union two years later in 1804.
