The discontent with Theresa did not show itself openly until 1127, when Alfonso Raimundes, who had succeeded his mother Urraca in the preceding year, and taken the title of Alfonso VII., King of Castile, Leon, and Gallicia, invaded Portugal and forced Theresa to recognize him as suzerain, and to surrender her claims to Tuy and Orense. The citizens of Guimaraens, the capital of the county, at once declared Affonso Henriques of age, and competent to reign; but Alfonso VII. marched against the city, and Egas Moniz, the former tutor of the young count, who was its governor, in order to make peace, promised on behalf of his former pupil that he would ratify Theresa’s submission. Affonso Henriques, however, though only a boy of seventeen, absolutely refused to recognize the submission made by his mother and his tutor, and in 1128 he raised an army with the declared intention of expelling Donna Theresa and her lover from the country. In this movement the boy was encouraged by Archbishop Paio and his brother Sueiro Mendes, by one of his brothers-in-law, Sancho Nunes, by his half-brother, Pedro Affonso, an illegitimate son of Count Henry, by Emigio Moniz, and by Garcia Soares. Donna Theresa also collected an army, consisting chiefly of Gallicians, but she was defeated by her son at the battle of S. Mamede, near Guimaraens, and taken prisoner, and was shortly afterwards expelled, with Don Fernando, from the county she had ruled so long. Thus ended the regency of Donna Theresa. She had not added a single town to her son’s dominions, for her early conquests had been recaptured by Queen Urraca and Alfonso VII. But she had done more for Portugal than making conquests. She had asserted its independence, and though she seldom called herself Queen, she never took any title less than that of Infanta. She had also prepared for the extension of Portugal towards the south at the end of her regency by encouraging the settlement of the orders of religious knights there. To the Knights Templars she had granted, in 1128, the frontier town of Soure; to the Knights of the Holy Sepulchre S. Payo de Gouvea, Lodeiro, and Paços de Penalva; and to the Knights of the Hospital, the town of Leça. From these beginnings great results were to arise during the reign of her son.
