The sources of his power were two-fold. In the first place he made himself the avowed champion of what may be called the popular part of the Constitution. His effort was to rescue the government from those corruptions which had kept Walpole so long in place, and had so long stifled all the popular sentiments of the nation. In the interests of this purpose he was the first to propose a reform of the House of Commons, as a result of which there might be something like a true representation of popular interests. The other source of his power was in the methods and characteristics of his eloquence. He was not in a true sense a great debator. His ability lay not in any power to analyze a difficult and complicated subject and present the bearings of its several parts in a manner to convince the reason. His peculiarities were rather in his way of seizing upon the more obvious phases of the question at issue, and presenting them with a nobility of sentiment, a fervor of energy, a loftiness of conception, and a power of invective that bore down and destroyed all opposition. During much of the time between 1735 and 1755 Pitt was in the opposition. When, on the fall of Walpole in 1741, Carteret came into power, Pitt assailed his narrow views and sordid methods with such energy that after three years he was given up as an object of merited reprobation. Pelham was now called to the head of affairs; but he would accept the office of First Minister only on condition that Pitt would take office under him. The King for a long time resisted; but, after a vain attempt to have a government formed under Pulteney, he gave his assent. Thus Pitt became Paymaster of the Forces in 1746, an office which he held till the death of Pelham in 1754. But on the accession of Pelham’s brother, the Duke of Newcastle, he once more fell into the opposition. The two years that followed were the most brilliant period of his oratory. The ministry gave him ample opportunities, and he took every occasion to improve them. Disasters abounded in every quarter of the British Empire. The loss of Minorca, the capture of Calcutta, the defeat of Gen. Braddock, the threatened invasion of England by the French, were themes well calculated to call forth his awful invective. The result was that Newcastle was driven from his place. Public opinion demanded that the reins now be placed in the hands of the only man fitted to hold them. Pitt became Prime Minister in December of 1756.
