A man of such powers and tastes in that day naturally became a pamphleteer. Outside of Parliament there was no other mode of discussing public affairs. The periodical press for purposes of discussion did not exist. During and after the Great Rebellion, the pamphlet had made its appearance as the chief instrument of controversy. Defoe used it freely after the Restoration. Swift made a great hit with it, and probably achieved the first sensational sale with his pamphlet on 'The Conduct of the Allies.' Bolingbroke's 'Patriot King' was a work of the same class. As a rule the pamphlet exposed or refuted somebody, even if it also freely expounded. It was inevitable that Burke should early begin to wield this most powerful of existing weapons. His antagonist was ready for him in the person of George Grenville, the minister who had made way for Burke's friend and patron Lord Rockingham. Grenville showed, as easily as any party newspaper in our own day, that Rockingham and his friends had ruined the country by mismanagement of the war and of the finances. Burke refuted him with a mastery of facts and figures, and a familiarity with the operations of trade and commerce, and a power of exposition and illustration, and a comprehension of the fundamental conditions of national economy, which at once made him famous and a necessary man for the Whigs in the great struggle with the Crown on which they were entering. The nature of this struggle cannot be better described in brief space than by saying that the King, from his accession to the throne down to the close of the American War, was engaged in a persistent effort to govern through ministers chosen and dismissed, as the German ministers are now, by himself; while the subservience of Parliament was secured by the profuse use of pensions and places. To this attempt, and all the abuses which inevitably grew out of it, the Whigs with Burke as their intellectual head offered a determined resistance, and the conflict was one extraordinarily well calculated to bring his peculiar powers into play. The leading events in this long struggle were the attempt of the House of Commons to disqualify Wilkes for a seat in the House, to punish reporting their debates as a breach of privilege, and the prosecution of the war against the American colonies. It may be said to have begun at the accession of the King, and to have lasted until the resignation of Lord North after the surrender of Cornwallis, or from 1770 to 1783.
