Biography

The reluctant PM

A reluctant prime minister - and known as one the best looking men in London - the Duke of Devonshire had no real thirst for political power, and his short time in office was dominated by Pitt the Elder.

George II had to work hard to persuade him to accept the position of prime minister. When he did, at the age of 36, the effective premier was Pitt the Elder, acting as Secretary of State.

The chief events of Devonshire’s term were the court martialling of a navy admiral for his failure to relieve Minorca, and a dispute with the Duke of Cumberland over the defence of Hanover.

Devonshire resigned after a lacklustre seven months. In 1764 he died in Germany, at a younger age than any other British PM - just 44 years old.

“Every King must make use of human means to attain human ends or his affairs will go to ruin.”

Did you know?

A tall man, Devonshire came from a powerful family of wealthy Whigs who had helped to establish the House of Hanover on the British throne.

Wife

Charlotte Elizabeth Boyle was 16-years-old when she married the Duke, 11 years her senior. Little is known about her life but she appears to have been a loyal wife, bearing the PM four children before her death in 1754 at the young age of just 23.
