From the late 1360s, Louis suffered from a skin disease with symptoms similar to leprosy. Thereafter he became even more zealous and dedicated more time to praying and religious contemplation. After his meeting with Louis in 1372, the papal legate, John de Cardailhac, stated: "I call God as my witness that I have never seen a monarch more majestic and more or one who desires peace and calm as much as he." He also changed the priorities of his foreign policy and began neglecting the Balkan states. Casimir III of Poland and Louis signed a treaty against Emperor Charles IV in Buda in February 1369. At their next meeting in Pressburg (now Bratislava in Slovakia) in September, Albert I of Bavaria, and Rupert I of the Palatinate joined their coalition against the emperor and the Habsburgs. However, Emperor Charles IV persuaded the two Wittelsbachs (Albert I and Rupert I) to break off the coalition in September 1370.
