The king of Poland was formerly an infidel, and son to the king of Lithuania, but, having a great ambition to reign, murdered his father, and was for this crime banished the country. He took refuge with the then king of Poland, who received him kindly, and admitted him into his friendship and confidence. He also gained the affections of the princes and nobles, insomuch that, on the death of their king, they unanimously elected this parricide to succeed him, had him baptised, and married him to the widow of the late king; and, since that time, he has happily enough governed that kingdom[53]. At this period, Sigismond king of Hungary, brother to the king of Bohemia, took to wife the sister of the above queen of Poland: they were daughters to a german count, called the count de Cilly, of the royal branch of Hungary[54]. The king of Poland laid claim to Hungary in right of his wife, and thence took occasion to harrass that country as well as Prussia. He sent secret messengers to the king of Lithuania, his cousin german and ally, to press him to invade Prussia on the quarter nearest the sea, when he would march his Polanders to form a junction and destroy the whole of it. His intentions were discovered by the messenger being arrested by orders of the king of Hungary, and information sent of them to Prussia, whenceforward the king of Hungary and grand master took such wise precautions that his future attempts were fruitless. [A. D. 1410.] CHAP. XVII. THE DUKE OF BERRY, BY THE KING’S COMMANDS, RETURNS TO PARIS.--THE MARRIAGE OF THE SON OF THE KING OF SICILY.--THE ASSEMBLY THAT IS HOLDEN AT MEUN LE CHASTEL. This year, the duke of Berry was, by the king’s orders, remanded to Paris, and, on his arrival, was sent, with the king of Navarre, to Giens sur Loire, to put an end to the quarrels between the duke of Brittany and the count and countess of Penthievre. Although both parties had promised to meet them, they did not personally attend, but sent commissioners. The king of Navarre and the duke of Berry took great pains, and proposed various means, to bring about a reconciliation. Finding all their attempts fruitless, they referred the whole matter, with the consent of the commissioners, to the king’s decision on All-saints-day next coming, and then they returned to Paris. In this year was concluded the marriage between the eldest son of Louis king of Sicily, and Catherine, daughter to the duke of Burgundy. The lady was conducted by sir John de Châlons, lord de Darlay, the lord de St George, sir William de Champdivers, and sir James de Courtjambe, to Angers, and there delivered to the queen of Sicily, who received her most affectionately and honourably,--and she magnificently entertained the knights who had brought her. After a short stay at Angers, they returned to their lord, the duke of Burgundy, at Paris.
