In 1517 Albany withdrew to France with a view to resuscitating the French alliance; the rivals Arran and Angus were again the two most powerful of the nobles; Margaret returned to Scotland, but quarrelled with her husband. In 1520 Albany was still in France which he probably found more cheerful than his own country. Angus got the better of Arran, who fled to France. There however Francis was still aiming at close alliance with England; and under such a combination of favourable conditions the truce between England and Scotland, entered upon in 1514 and now about to terminate, was extended for a couple of years. But Margaret herself being now hostile to Angus, there was every prospect that, should Albany return to Scotland, Wolsey would have to reckon seriously with the anti-English party there as a factor in his diplomatic relations with France. [Sidenote: 1520-21 Affairs abroad] The closing months of 1520 arid the opening months of 1521 witnessed events of importance at the time-and one at least which had very far-reaching consequences. The Emperor's wide do-minions were disturbed by a local outbreak in Germany, a revolt in Spain, and an attempt on the part of the claimant to the throne of Navarre to recover that territory. The Diet of the Empire met at Worms, and Martin Luther was cited before it; with the result that the Empire was practically divided into two camps, Charles ranging himself on the papal side. As Henry VIII. was so far a loyal son of the Church, wielding an anti-Lutheran pen in theological controversy, while the French King's reverence for the papacy was under suspicion, the present tendency of this event was favourable to the union of Charles and Henry with the Pope against Francis. On the other hand there was very little question that the troubles in the Emperor's dominions were fostered by Francis, who was preparing for an Italian expedition. Had Charles and Wolsey trusted each other, their alliance would certainly have been drawn closer; but Wolsey was not the man to take up Charles's cause without securing an adequate return, while Charles wished to involve England on the strength of promises which he expected subsequently to find no necessity for carrying out. Charles found his justification in the unexpected success of his arms in Navarre, in Spain, and in Germany. Good fortune relieved him from the more pressing need of English aid, and thus the prospect of a close and active alliance faded. [Sidenote: 1521 Buckingham]
