of Lipá, gained the trust of John. The other party, led by Vilém Zajíc of Valdek (Latin: Wilhelmus Lepus de Waldek; German: Wilhelm Hase von Waldeck), convinced the Queen that the intent of Lord Lipá was to overthrow John. Consequently, in 1315 John had Jindřich imprisoned. By 1318 John had reconciled with the nobility and recognised their rights along with taking a further step to establish dualism of the Estates and a division of government between the king and the nobles. International politics Foreign politics, rather than Czech, appealed to John, as he was gifted at it. With the help of his father Henry, John was able to pressure the Habsburgs in reaching an agreement over Moravia. He was also able to pressure the House of Wettin, princes of Saxony, to give over the territory lying to the northern border of the Czech state. John also decided to reach out to improve the relations with the Silesian principalities, which were close, both in economic and political standings, to Bohemia and Moravia. The international spectrum was further broadened for John when his father named him Vicar General, his deputy for the governance of the Empire. This allowed for John to reach further and he was able to contribute to the imperial coronation along with helping with the conclusion of the Italian territorial wars. In 1313 Henry died suddenly bringing an end to this collaboration between him and John. However, through Henry's death a spot for the imperial crown opened up making John a possible candidate, the other two candidates being Fredrick of Habsburg and Louis of Bavaria. In attempts to not support Fredrick, John voted for Louis at the diet of electors. In return for his support, Louis, as the new emperor, promised the support in territorial claims of the Czech state in Silesia and Meissen as well as the region of Cheb and the Upper Palatinate. Later in 1319, after the Brandenburg House of Ascania died out, John regained control over the Bautzen region and then the Görlitz region in 1329. In 1322/23 King John became unsettled by Louis's growing power and allied with France and Austria against him. The dispute would escalate with his son Charles claiming the Imperial crown in opposition to Louis. Death John lost his eyesight at age 39 or 40 from ophthalmia in 1336, while crusading in Lithuania.
