Another result of the wars of France and Spain was the frequent internal quarrels at Malta. As the feelings of the two nations towards each other were often embittered, it is not surprising to find that French and Spanish Knights would come to open blows in the streets of Valetta. The unhealthy life of those young and idle aristocrats was conducive to turbulence, and the Grand Masters often adopted the policy of sending them to sea as soon as trouble was foreseen. The French were generally in the preponderance, as we can see from the great number of French Grand Masters; and the increasing greatness of the French monarchy in the seventeenth century was reflected at Malta.
The position of the Maltese became worse and worse as the Order declined. The natives, who had enjoyed a considerable measure of local autonomy under Spanish rule, had been very reluctant to submit to the Knights, and had protested to Charles V. against their surrender to the Order, as a violation of the promise given in 1428 by Alphonse of Sicily that Malta would never be separated from the Sicilian Crown. They knew that the Order would conduct itself in Malta as a garrison in a fortress, and that this would mean strict military control over the inhabitants. It was also probable that the Turks would again besiege the Knights, as they had done at Rhodes in 1480 and 1522, and the Maltese were strongly averse to being drawn into such danger.
During the residence of the Knights the native population of Valetta was considerably modified. Some of the Rhodians who had, in 1523, accompanied the Knights, came with them to Malta; mercenaries who fought for the Order sometimes stayed on in the island, and many in this new population were illegitimate children of the Knights. For, though the vow of chastity was insisted on to the end as a condition of entrance into the Order, in practice, by the eighteenth century, it had become entirely ineffective.
