In Spain and Portugal, Innocent found irregular marriages almost as numerous as regular, and his interventions show the same unedifying mixture of priestly rigour and political compromise. Sacerdotal legislation had by this time surrounded marriage with a portentous series of obstacles--forbidden degrees of spiritual and carnal affinity--which sacerdotal power alone could remove, yet the isolated princes of the Peninsula were compelled to marry constantly into each other's families and did not always ask the costly blessing of the Papacy. That this legislation did not improve the sex-morals of Europe, which were at least no better than they had been in pagan times, is well known. Spain was particularly lax, having contracted the gaiety of neighbouring Provence, and her kings may have felt that where unwedded love was so genially tolerated, these academic restraints on wedded love might be disregarded. Innocent placed the kingdoms of Leon and Castile under an interdict because the King of Leon had married his cousin, Berengaria of Castile, and, when the court of Leon ignored his censures, he predicted that there would be a horrible issue of the unhallowed union. Its first fruit was St. Ferdinand; but Berengaria nervously retired after a few years and left the King to bear his excommunication with Spanish dignity. The King of Castile soon obtained the removal of the interdict, on the ground that it favoured the growth of heresy, but he was then threatened with excommunication because he permitted the Jews to become rich while the Church was poor. Pedro of Aragon was more fortunate. In the course of a journey to Rome he married the wife of the Count de Comminges, and the Pope at once accepted her assurance that the Count had two wives living when he married her, and blessed the union. Pedro, it should be added, swore fealty and an annual subsidy of two hundred gold pieces to the Pope. The King of Navarre incurred an interdict for allying himself with the Moors. All that one can seriously put to the credit of Innocent is that he greatly aided the unification of Spain by spurring its kings to a common crusade against the Moors; if we may assume that the crusade favoured the progress of civilization in the country. Sancho of Portugal also felt, and disdained, the touch of the Papal whip. When Innocent complained of his oppression of the clergy, he threatened--in a letter which Innocent describes as the most insolent ever written to a Pope--to strip his corrupt priests of all their wealth. Innocent at once temporized, but a dangerous illness and fit of repentance soon put Sancho and the kingdom of Portugal at his feet. At his death Sancho left the kingdom wholly subject to Rome and the clergy, though it was not many years before the quarrels of his children again drew upon it the spiritual blight of an interdict.
