an active life.[62] She was naturally just and upright, though, in the tortuous policy of the time, she had no hesitation in becoming the accomplice of Ferdinand's frequent duplicity and treachery. With all the crowded activity of her eventful life, she found time to stimulate the culture despised by the warlike chivalry around her, and she took a deep interest in an academy which, at her instance, was opened for the young nobles of her court by the learned Italian, Peter Martyr of Anghiera.[63] [Sidenote: _ROYAL JURISDICTION_] Isabella recognized that the surest way to curb the disorders which pervaded her kingdom was the vigorous enforcement of the law and, as soon as the favorable aspect of the war of the succession gave leisure for less pressing matters, she set earnestly to work to accomplish it. The victory of Toro was followed immediately by the Córtes of Madrigal, April 27, 1476, where far-reaching reforms were enacted, among which the administration of justice and the vindication of the royal prerogatives occupied a conspicuous place.[64] It was not long before she gave her people a practical illustration of her inflexible determination to enforce these reforms. In 1477 she visited Seville with her court and presided in public herself over the trial of malefactors. Complaints came in thick and fast of murders and robberies committed in the bad old times; the criminals were summarily dispatched, and a great fear fell upon the whole population, for there was scarce a family or even an individual who was not compromised.
