George of Poděbrady
In 1461, George of Poděbrady began aspiring to the crown of the Holy Roman Emperor, which would surely have meant renouncing the chalice of Hussitism. This led Jan Rokycana to speak against George of Poděbrady in his sermons. On 7 February 1465 he took part in a dispute over the king's ministry, after which the king requested greater cooperation from the church. A year later, in 1466, Jan Rokycana suffered a stroke, after which he started to have trouble speaking. He was buried in Týn church.
