The short reign of this prince was not without its troubles. An insurrection broke out among those most restless and faithless of subjects, the Sardinians. As usual, the efforts of his generals to repress it were but partially successful. The affairs of Sicily were not more promising. None of these commotions appears to have occasioned King Juan the least anxiety: he resumed his diversions, that of hunting especially, with as much eagerness as before, leaving the cares of government to his queen. One day, while occupied in this favourite occupation in the forest of Foja, he fell from his horse, and was killed on the spot. On receiving intelligence of this catastrophe Aragon, Catalonia, and Valencia proclaimed Don Martin, brother of the late king, who was then in Sicily supporting the rights of his son and daughter-in-law, sovereigns of that island. This choice gave great umbrage to Matthieu count de Foix, who had married the eldest daughter of Juan, and who contended that the crown belonged to him in her right. He collected troops and penetrated into Catalonia; but he found the inhabitants averse to his pretensions, and indignant at his proceedings. As the states were sitting at Saragossa, he now adopted the wiser mode of deputing ambassadors to that assembly, with instructions to espouse his rights, which, according to the laws of legitimate succession, were well founded. But Aragon had seen only one female sovereign, Doña Petronilla, and had for some time been inclined to consider the Salic law as tacitly in force. The count met with a repulse both there and at Barcelona; but he hoped that arms would be more effectual than arguments; and, with a second and more numerous army, he invaded Aragon. There he and his countess solemnly assumed the royal title and arms, and reduced several towns; but he was soon compelled to retire into Navarre. [Sidenote: [1408-1412 A.D.]]
