Sir William Wyndham, 3rd Baronet

Sir William Wyndham, 3rd Baronet (born 1687, Orchard Wyndham, Somerset, Eng.—died June 17, 1740, Wells, Somerset) was an English Tory politician, a close associate of Henry Saint John, 1st Viscount Bolingbroke.

A member of Parliament (1710–40), Wyndham was appointed secretary of war in 1712, chancellor of the Exchequer in 1713, and head of the Treasury in 1714, all at Bolingbroke’s behest. He was privy to Bolingbroke’s intrigues with James Edward, the Old Pretender, and became head of the English Jacobites. He was eventually arrested (September 1715), and, although he escaped, he then voluntarily surrendered, and no proceedings were taken against him.

Wyndham became Bolingbroke’s political mouthpiece and the leader of an opposition to Robert Walpole. From 1726 onward this opposition, composed of Tories and discontented Whigs, made great noise with its propaganda, but its parliamentary performance was generally disappointing, though Wyndham himself was a popular leader. In the 1730s Wyndham and Bolingbroke supported Frederick Louis, Prince of Wales, in his quarrels with his father, King George II. They also attacked Walpole’s foreign policy, but when the tide was turning against Walpole, Wyndham’s death in 1740 weakened the cohesion of the combined opposition.
