Don John's early life was passed in the farm-house of a rich peasant in the vicinity of Liege, where the young lad was subjected to all manner of privations, and early inured to hard labour and coarse fare,--a fitting preparation for his future career. Brantôme mentions it as a fact much to Don John's credit, that, in spite of this humble education as a peasant, he showed no trace of vulgarity in after life, but, on the contrary, that he had excellent and noble manners in the field and in drawing-rooms. The emperor, Charles V., sent for the lad, when he grew up, to come to Spain, rewarded the honest peasant for his trouble, and announced to Don John the secret of his birth. Although the Emperor loved the boy as the son of his old age, he gave him nothing during his lifetime, of which the ardent young prince much complained, saying that "the Emperor, having acknowledged him as his son, should have given him the means of living befitting his rank and birth." At his death, Charles left Don John nothing but a strong recommendation to his successor Philip II. The only wish which escaped the dying monarch was, that Don John should be educated for the church. Meanwhile, Don John, who was but one year younger than Don Carlos, was brought up with Philip's ill-starred son: and at this period of his life a circumstance occurred which greatly influenced Don John's future destiny. The boy revealed to Philip II. some hare-brained folly of his son Don Carlos. This conduct gave the Spanish monarch so high an opinion of his young brother's integrity and honour, that he determined not to follow out Charles V.'s intentions, but to educate Don John for the military, instead of the ecclesiastical profession. This was not done, however, without strong opposition from some of Philip's royal council. The conduct of Don John, however pleasing to Philip II., drew upon the young prince the bitter animosity of Don Carlos who, ever after, treated his companion with marked indignity: his hatred one day went to the length of twitting Don John with his illegitimacy. Don Carlos called him a bastard, _hijo de puta_. "Yes," said Don John, "I am a bastard; but my father is a better man than yours:" whereupon the two lads came to blows. Passing over much of his early life, we come to the year 1569, when Don John was sent against the Moors of Grenada. In this expedition he developed considerable military talents, and gave such evidence of personal courage, that the old captains and veteran soldiers who remembered the early campaigns of his father, Charles V., called out with one accord, "Ah! this is a true son of the Emperor." _Ea! es verdadero hijo, del Emperador._ Don John returned from this campaign covered with glory, and with the reputation of being one of the best captains of the age.
