The enslaved Moor was his master's property, like his cattle, but entitled to some safeguards of life and limb. Even baptism did not manumit him unless the owner were a Moor or a Jew.[169] That he was frequently a man of trained skill and education is seen in the provision that, if his master confided to him a shop or a ship, the former was bound to fulfill all contracts entered into by his slave.[170] Thus the free Castilian, whose business was war, had his trade and commerce to a considerable extent, as well as his agriculture, carried on by slaves, and the rest was mostly in the hands of the Jews and the free Moors or Mudéjares. Labor thus became the badge of races regarded as inferior; it was beneath the dignity of the freeman, and when, as we shall see hereafter, the industrious population was expelled by bigotry, the prosperity of Spain collapsed. [Sidenote: _THE MUDÉJARES_] As for the Mudéjares, the practice of allowing them to remain in the reconquered territories began early. Even in Galicia they were to be found, and in Leon documents of the tenth century contain many Moorish names among those who confirm or witness them.[171] The Fuero of Leon, granted by Alfonso V in 1020, alludes to Moors holding slaves, and the Berber population there is still represented by the Maragatos, to the south-west of Astorga--a race perfectly distinct from the Spaniards, retaining much of their African costume and speaking Castilian imperfectly, although it is their only language.[172] Fernando I (1033-65), who rendered the Kings of Toledo and Seville tributary, and who was besieging Valencia when he died, alternated in his policy towards the inhabitants of his extensive conquests. In the early part of his reign he allowed them to remain; then he adopted depopulation, and finally he returned to his earlier methods.[173] Alfonso VI followed the more liberal system; when he occupied Toledo, in 1085, he granted a capitulation to the inhabitants which secured to them their property and religion, with self-government and the possession of their great mosque.[174] When, during his absence, the Frenchman, Bernard Abbot of Sahagun, newly elected to the archbishopric, in concert with his queen, Constance of Burgundy, suddenly entered the mosque, consecrated it and placed a bell on its highest minaret, Alfonso was greatly angered. He hastened to Toledo, threatening to burn both the queen and the archbishop, and only pardoned them at the intercession of the Moors, who dreaded possible reprisals after his death. His policy, in fact, was to render his rule more attractive to the Moslem population than that of his tributaries, the petty _reyes de taifas_, who were obliged to oppress their subjects in order to satisfy his exigencies. He even styled himself _Emperador de los dos cultos_. His tolerant wisdom justified itself, for, after the coming of the Almoravides, in spite of the disastrous defeats of Zalaca and Uclés, he was able to hold his own
