Pleasant though the recognition was, however, the pecuniary assistance was quite insufficient to accomplish Margaret's purpose. For nine years Edward IV. sat on his throne and no serious efforts were made to dislodge him. As he never forgot his mother's lineage, the sympathies of Charles of Burgundy were with the exiles, and Queen Margaret may have counted confidently on that sympathy proving valuable for her son as soon as Charles himself had a free hand. But when he came into his heritage, his marriage with Margaret of York put a definite end to those hopes. The new duke thereby declared his acceptance of the king whom the Earl of Warwick had seated upon the English throne. Then came clashing of wills between that king and his too powerful subject-adviser.[4] To punish his unruly royal protégé, Warwick turned his attention to the Duke of Clarence, brother and heir presumptive to Edward IV. A marriage was planned between this possible future monarch and the earl's eldest daughter and then quickly celebrated at Calais without the king's knowledge (July, 1469). In the same summer occurred a rising in Yorkshire, possibly instigated by Warwick.[5] The malcontents, sixty thousand strong, declared that the king was giving ear to base counsellors and must be coerced into better ways. An attempt to suppress this revolt by the royal troops resulted in a pitched battle where Earl Rivers, the father of Elizabeth Woodville, the young queen, was taken prisoner and beheaded. Edward, baffled, finally turned for aid to Warwick. Over the Channel hastened the earl and his new son-in-law, levied troops, met the king at Olney, and--Edward found himself if not exactly a prisoner, at least under restraint. Two sovereigns--both without power even over their own actions,--such was the situation in England at the end of 1469, when Charles of Burgundy was self-complacently regarding Louis XI. as a foe convinced of his own inferiority. A menacing letter from this redoubtable ducal brother-in-law was probably the reason why Edward IV. was set at liberty, and why a reconciliation was patched up between him and his councillor, with full pardon for Warwick's adherents. But it was short-lived. A fresh outbreak in March, 1470, made another change. Warwick and Clarence sided with the rebels, the king was victorious, and his unfaithful friend and brother were again forced to flee under a shower of menaces hurled after them. "But, and He [Clarence] or Richart Erle of Warrewyk our Rebell and Traytour come into oure seid Land we woll ... that ye doo Hym and Theym to be arrested ... He that Taketh and Bryngeth unto Us either of theym, he shal have for his Reward C._l_ of Land in Yerely Value to Hym and to his Heyres or Mil. _Lib_ in Redy money at his election."[6] Such was the proclamation issued on March 22d by the king himself at York.
