With his third Parliament he got on no better. In it two great men sprang to the front—Sir Thomas Wentworth, afterward Lord Strafford, and Sir John Eliot, who had already shown himself a leader of the party that stood for free representative institutions as against the unbridled power of the King. Eliot was a man of pure and high character, and of dauntless resolution, though a good deal of a doctrinaire in his belief that Parliamentary government was the cure for all the evils of the body politic. Wentworth, dark, able, imperious, unscrupulous, was a born leader, but he had no root of true principle in him. At the moment, from jealousy of Buckingham, and from desire to show that he would have to be placated if the King were awake to self-interest, he threw all the weight of his great power on the popular side. Instead of giving the King the money he wanted, Parliament formulated a Petition of Right, demanding such elementary measures of justice as that the King should agree never again to raise a forced loan, or give his soldiers free quarters on householders, or execute martial law in time of peace, or send whom he wished to prison without showing the cause for which it was done. The last was the provision against which Charles struggled hardest. The Star Chamber—a court which sat without a jury, and which was absolutely under the King’s jurisdiction—had been one of his favorite instruments in working his arbitrary will. The powers of this court were left untouched by the Petition: yet even the service this court could render him was far less than what he could render himself if it lay in his power arbitrarily to imprison men without giving the cause. However, his need of money was so great, and the Commons stood so firm, that he had to yield, and on June 7th, in the year 1628, the Petition of Right became part of the law of the land. The first step had been taken toward cutting out of the English Constitution the despotic powers which the Tudor kings had bequeathed to their Stuart successors.
