John Stuart, 1st Marquess of Bute


John Stuart, 1st Marquess of Bute PC, FRS, styled Lord Mount Stuart until 1792 and known as the Earl of Bute between 1792 and 1794, was a British nobleman, coalfield owner, diplomat and politician who sat in the House of Commons from 1766 to 1776.

Early life

Stuart was born at Mount Stuart House on the Isle of Bute, the son of prime minister John Stuart, 3rd Earl of Bute, and his wife Mary Wortley Montagu. He was educated at Harrow School and Winchester College. He went to the University of Oxford, where he had private tuition from James Bladen. The degree of D.C.L., awarded to him by the university in 1793, was honorary.
Around 1757 Stuart began to be tutored by the philosopher Adam Ferguson.

Political career

Lord Mount Stuart was returned as Tory Member of Parliament for Bossiney at a by-election in 1766. He was returned in the general elections of 1768 and 1774.
On 2 November 1775, he announced in the House of Commons his intention to introduce a bill to establish a militia in Scotland, and during the next few months James Boswell assisted in seeking support for the bill in Scotland. In March 1776 the bill was debated, but ultimately failed to pass. He left the House of Commons in 1776 when he was elevated to the Peerage of Great Britain in his own right as Baron Cardiff, of Cardiff Castle in the County of Glamorgan. Though this title was also used, he continued to be known by his courtesy title of Lord Mount Stuart. He served as Lord Lieutenant of Glamorgan from 1772 to 1793 and, from 1794 to his death, taking command of the Glamorgan Militia as Lieutenant-Colonel Commandant when it was embodied on 26 March 1778.
In 1779, Lord Mount Stuart was sworn of the Privy Council and was sent as an envoy to the court of Turin. He was ambassador to Spain in 1783.
He held the sinecure of Auditor of the imprests from 1781 until the abolition of the office in 1785, upon which he was paid £7000 compensation. He was the first Lord Lieutenant of Buteshire from 1794 until his death.
Lord Mount Stuart succeeded his father in the earldom in 1792. In 1794 he was created Viscount Mountjoy, in the Isle of Wight, Earl of Windsor and Marquess of Bute. Lord Bute was inducted as a Fellow of the Royal Society on 12 December 1799.
