Count Henry was the second son of Henry, who was the third son of Robert, first Duke of Burgundy, and he was like his father and grandfather, a knight of the old French school, combining a passionate love for adventure and for war with an ambitious and self-seeking temperament. He had come to Spain to the assistance of the Christians, as much with the purpose of founding a dynasty as for the love of war, and from the first he turned his thoughts more to the hope of succeeding his father-in-law, Alfonso VI., in one at least of his kingdoms, than to carving a kingdom for himself out of the dominions of the Arab caliphs. He received his county of Portugal, the dowry of his wife, Theresa, illegitimate daughter of Alfonso VI., as a direct fief of the crown of Gallicia, one of the three kingdoms of his father-in-law. This kingdom Alfonso had granted, as a fief, not as a kingdom, to Count Raymond of Toulouse, who had married his legitimate daughter, Urraca, and Count Henry highly disapproved of being in some sort a feudatory of his fellow-adventurer. At first the jealousy between Henry and Raymond did not show itself; for Count Henry had to fight hard to defend his southern frontiers against the incursions of the Mohammedan general Seyr. To his help he summoned the chivalry of France, and the knights of his native country flocked to his assistance, and were promoted to high military positions and to feudal dignities by him. Battle succeeded battle without either side gaining any decisive victory, until after seven years’ hard fighting both Christians and Moors decided to rest awhile to recover from their exhaustion. Count Henry was, however, too much the restless knight of the Middle Ages to remain quiet long. Since his Portuguese warriors were weary, and the battle-ground for miles on each bank of the Tagus was laid utterly waste, he could fight no longer in his own country against the unbelievers, and so hurried off in 1103 with Maurice, Bishop of Coimbra, to fight them in Palestine. For two years he served in the expedition known as the Second Crusade, and when he returned he was still ready for more fighting at home. His restlessness was typical of his epoch. The knights of the Crusades were always knights-errant, always in search of adventure, and never satiated with war. This spirit was encouraged by the Church, and while the Almoravide caliph Yūsuf was organizing his military forces for a fresh assault on the Christians, Count Henry, on the other hand, went off in search of adventure abroad, leaving his county under the government of his wife, Theresa.
