The youngerPitt's prime ministerial tenure, which came during the reign of George III, was dominated by major events in Europe, including the French Revolution and the Napoleonic Wars.
William Pitt the Younger, the son of William Pitt the Elder (afterwards Earl of Chatham) and the Lady Hester Pitt, was born in Hayes, Kent.
Pitt the Younger was the second son and fourth child out of five; his elder brother, John Pitt, also had a political career.
Pitt, the first real Imperialist in modern English history, was the directing mind in the expansion of his country, and with him the beginning of empire is rightly associated.
The first and most important of a series of changes which ultimately led to the dissolution of the ministry was the death of George II on 25 October 1760, and the accession of his grandson, George III.
He was the first to discern that public opinion, though generally slow to form and slow to act, is in the end the paramount power in the state; and he was the first to use it not in an emergency merely, but throughout a whole political career.
