Various forces were at work, however, which were soon to undermine the peace and tranquillity of the gay court, and plunge it into deepest woe. It should be known that by a former division of the possessions of the royal house of Naples, which had been dictated by the whim of a partial father, the elder branch of that house had been allotted the kingdom of Hungary, which had been acquired originally as the dowry of a princess, while to the younger branch of the house Naples and Provence had been given. Such a division of the royal domain had never satisfied those of the elder branch of the family, and for many years the rulers of Hungary had cast longing eyes upon the fair states to the south. The good King Robert, desiring in his heart to atone for the slight which had been put upon them, decided to marry Joanna to his grand-nephew Andreas, the second son of Carobert, King of Hungary, thus restoring to the elder branch of the family the possession of the throne of Naples without endangering the rights of his granddaughter, and at the same time extinguishing all the feuds and jealousies which had existed for so long a time between the two kingdoms. So the young Hungarian prince was brought to the Neapolitan court at once, and the two children were married. Joanna was but five years old and Andreas but seven when this ill-fated union was celebrated, with all possible splendor and in the midst of great rejoicing. The children were henceforth brought up together with the idea that they were destined for each other, but as the years grew on apace they displayed the most conflicting qualities of mind and soul.
