From Wales Edward turned his arms against Scotland. There Columban had in former days anointed as king a Scottish prince, who was also of Keltic descent; how the German element nevertheless got the upper hand not merely in the greatest part of the country, but also in the ruling family, is the great problem of early Scottish history: a thoroughly Germanic monarchy had arisen, but one which after it had once given a home to the Anglo-Saxons who fled before the Normans, thought its honour concerned in repelling all English influences. A disputed succession gave Edward I an opportunity of reviving the claims of his predecessors to the overlordship of Scotland: he gave the Scotch a king, whom the Scotch rejected simply because he was the English King's nominee. The war, which sometimes seemed ended--there were times at which Edward could regard himself as the Lord of all Albion,--ever blazed out again; above all, the support the Scotch received from the King of France brought about complications which filled all Western Europe with trouble and war; but it was in the home politics of England that their effect was destined to be greatest. Compelled to make incessant efforts, which exhausted the resources of the crown, Edward appealed to the voluntary assistance of his subjects. He laid down to them the principle, that their common perils should be met with their united strength, that what concerns all must also be borne by all. In the war against Wales he had gathered together the representatives of the counties and the towns, to hear his demands and to act accordingly; chiefly to vote him subsidies. After the victory he had called an assembly of nobles, knights, and towns, to take counsel with them about the treatment of the captives and the country. Similarly he drew together the representatives of the towns in order to decide the affairs of Scotland. With especial emphasis did he call for their united help against Philip the Fair of France, who thought to destroy the English tongue from off the earth: knights and towns were pledged to help in carrying out the resolutions thus adopted by common consent. In spite of all this appealing to free participation in public matters, Edward I did not refrain from the arbitrary imposition of taxes, and those the most oppressive: the eighth, even the fifth part of men's income. For the campaign in Flanders he summoned the under-tenants as well as the tenants in chief. We find instances of arbitrary seizure of whatever was necessary for the war.
