Sancho, the second son of Jayme II., succeeded as King of Majorca on June 4, 1311. He was a just and peace-loving sovereign, beloved by his people, always on excellent terms with his cousins of Aragon, and he reigned prosperously for thirteen years. Majorca was a feudatory of Aragon, with the duty of assisting in the wars of the suzerain; and the King was required to attend the Cortes of the Aragonese kingdom to arrange the nature and amount of aid to be contributed to the feudal overlord.
As a boy Sancho had suffered imprisonment with his brothers Felipe and Fernando, when they were captured by the young tyrant Alfonso III., first at Torrella de Monguin, then at Gerona, and finally at Barcelona, where they were released on Alfonso’s death. The misfortunes of his boyhood were not continued in after-life. His reign was prosperous. On his accession he swore to maintain the privileges and freedom of his people; and the commerce of the island made great progress under his fostering care.
Sancho married Maria, daughter of the Angevin King of Naples, but had no children by her. They both adopted the infant son of the chivalrous younger brother Fernando. The King of Majorca was in a position calling for much tact and diplomatic skill on the one hand, and for energetic defensive measures on the other. He had to be well prepared against attacks of pirates from the coasts of Barbary, to preserve his Continental dominions from French encroachments, and to maintain a good understanding with his cousin of Aragon.
A fleet of armed ships was equipped for defence against piratical attacks, half by the King and half by the Jurados. It consisted of four galleys, two galleots, and several smaller vessels. Later, the _atalayas_, or watch-towers, were built along the coasts, which gave notice of the approach of an enemy by fire-signals. In 1316 King Sancho proceeded from Perpignan to Avignon for an interview with the Pope respecting French claims on the Barony of Montpellier. The negotiations were transferred to Paris, and a satisfactory settlement was arrived at. With Aragon Sancho continued to maintain the most friendly relations. When the conquest of Sardinia and Corsica was resolved to be undertaken, he attended personally at the Cortes held at Gerona in June 1322 as a feudatory of Aragon. The result was that Majorca contributed twenty new galleys to the expedition, two hundred mounted knights, besides a contingent of foot soldiers. King Jayme II. of Aragon was so much pleased with this evidence of good will on the part of his cousin of Majorca that he expressed his satisfaction by exempting King Sancho from the duty of personal attendance at the Cortes of Aragon.
