John Fane, 11th Earl of Westmorland GCB GCH PC (3 February 1784 – 16 October 1859),[1] styled Lord Burghersh until 1841, was a British soldier, politician, diplomat, composer and musician.

His sister was the social hostess Sarah Villiers, Countess of Jersey, and his uncle was William Lowther, 1st Earl of Lonsdale, a Tory magnate from northern England.

Three days later he joined Brooks's Club, traditionally a resort of Whigs and particularly Foxite, but on 30 April 1806 voted with the Pitt administration (in which his father was Lord Privy Seal) against the repeal of the Additional Forces Acts 1803.

Burghersh was a supporter of the second Portland Ministry, in which his father was again Lord Privy Seal, but without particular activity in Parliament, appearing once in the debate on the price of wheat on 3 June 1808.

[3] On 6 May 1809, he was gazetted major in the 2nd West India Regiment in place of Thomas McMahon, sent to Lord Beresford's staff in Portugal,[7] and lieutenant colonel on 9 May when he was himself sent to Portugal,[8] This exceedingly rapid promotion, over the heads of many senior officers, drew the attention of William Shipley, member for Flint and recently retired as a lieutenant colonel.

He soon after replied to a letter of his father's on his abortive promotion in May, telling him that "the military is a profession which I most sincerely love," but expressing his frustration at not occupying a situation more equal to his education and qualities.

Westmorland defended his conduct by arguing that while he was "no Jacobin" and had no sympathy with the revolutionaries, he was concerned that the Austrians would put down the revolution with such brutality that further political disturbance was inevitable.

Lord Westmorland married Priscilla Anne Pole-Wellesley, daughter of the Honourable William Wellesley-Pole, later first Baron Maryborough and third Earl of Mornington and Katherine Elizabeth Forbes, on 26 June 1811.
