It may readily be understood how these influences of Islamic thought and practice—added to definite efforts at conversion [428]—would lead to much more than a mere approximation and would very speedily swell the number of the converts to Islam so that their descendants, the so-called Muwallads—a term denoting those not of Arab blood—soon formed a large and important party in the state, indeed the majority of the population of the country, [429] and as early as the beginning of the ninth century we read of attempts made by them to shake off the Arab rule, and on several occasions later they come forward actively as a national party of Spanish Muslims. We have little or no details of the history of the conversion of these New-Muslims. Instances appeared to have occurred right up to the last days of Muslim rule, for when the army of Ferdinand and Isabella captured Malaga in 1487, it is recorded that all the renegade Christians found in the city were tortured to death with sharp-pointed reeds, and in the capitulation that secured the submission of Purchena two years later, an express promise was made that renegades would not be forced to return to Christianity. [430] Some few apostatised to escape the payment of some penalty inflicted by the law-courts. [431] But the majority of the converts were no doubt won over by the imposing influence of the faith of Islam itself, presented to them as it was with all the glamour of a brilliant civilisation, having a poetry, a philosophy and an art well calculated to attract the reason and dazzle the imagination: while in the lofty chivalry of the Arabs there was free scope for the exhibition of manly prowess and the knightly virtues—a career closed to the conquered Spaniards that remained true to the Christian faith. Again, the learning and literature of the Christians must have appeared very poor and meagre when compared with that of the Muslims, the study of which may well by itself have served as an incentive to the adoption of their religion. Besides, to the devout mind Islam in Spain could offer the attractions of a pious and zealous Puritan party with the orthodox Muslim theologians at its head, which at times had a preponderating influence in the state and struggled earnestly towards a reformation of faith and morals.
