Although royalists were excluded from the polls, the Independents were unable to control a majority in the general election, for, it must be remembered, they formed a very small, though a powerful, minority of the population. The Presbyterians in the new Parliament, with characteristic stubbornness, quarreled with Cromwell, until he abruptly dismissed them (1655). Thenceforth Cromwell governed as a military dictator, placing England under the rule of his generals, and quarreling with his Parliaments. To raise money he obliged all those who had borne arms for the king to pay him 10 per cent of their rental. While permitting his office to be made hereditary, he refused to accept the title of king, but no Stuart monarch had ruled with such absolute power, nor was there much to choose between James's "_a deo rex, a rege lex_" and Cromwell's, "If my calling be from God and my testimony from the people, God and the people shall take it from me, else I will not part from it." The question is often raised, how Cromwell, representing the numerically insignificant Independents, contrived to maintain himself as absolute ruler of the British Isles. Three circumstances may have contributed to his strength. (1) He was the beloved leader of an army respected for its rigid discipline and feared for its grim mercilessness. (2) Under his strict enforcement of law and order, trade and industry brought domestic prosperity. (3) His conduct of foreign affairs was both satisfactory to English patriotism and profitable to English purses. Advantageous commercial treaties were made with the Dutch and the French. Industrious Jews were allowed to enter England. Barbary pirates were chastised. In a war against Spain, the army won Dunkirk; and the navy, now becoming truly powerful, sank a Spanish fleet, wrested Jamaica from Spain, and brought home ship-loads of Spanish silver. The weakness of Cromwell's position, however, was obvious. Cavaliers were openly hostile to a régime of religious zealots; moderate Anglicans would suffer the despotism of Cromwell only as long as it promoted prosperity; Presbyterians were anxious to end the toleration which was accorded to all Puritan sects; radicals and republicans were eager to try new experiments. [Sidenote: Disorganization following the Death of Oliver Cromwell] The death of Cromwell (1658) left the army without a master and the country without a government. True, Oliver's son, Richard Cromwell (1626-1712), attempted for a time to fill his father's place, but soon abdicated after having lost control of both army and Parliament. Army officers restored the Rump of the Long Parliament, dissolved it, set it up again, and forced it to recall the Presbyterian members who had been expelled in 1648, and ended by obliging the reconstituted Long Parliament to convoke a new and freely elected "Convention Parliament." Meanwhile, General Monck opened negotiations for the return of Charles II. THE RESTORATION: THE REIGN OF CHARLES II
