The Duke of Portland : politics and party in the age of George III

The Third Duke of Portland served twice as Prime Minster and had a long and distinguished political career from 1760s to the 1780s.

This study details how he was transformed from a pillar of the grand Whiggery (he was the brother in law of Georgiana, Duchess of Devonshire) into the figurehead for would be Tories.

The book also examines how he played an important public role in many of the political crises of his era (including the French Revolution and the Union) as well as a hidden role in British history (he was involved in the secret service and political corruption).
