John of Rokycan

John of Rokycany, also known as Jan of Rokycany, in Czech language Jan Rokycana, and Jan z Rokycan (c. 1396 in Rokycany, Bohemia - February 21, 1471 in Prague) was a Czech Hussite theologian in the Kingdom of Bohemia and a key figure in Bohemian church history.

In his youth, Jan Rokycana entered the Augustinian monastery in Rokycany. Later, he left the monastery to study in Prague, gaining his baccalaureate in 1415. He joined the movement against Jan Želivský, after which he had to flee from Prague. He also opposed the Taborites, most notably at Konopiště in 1423. Later in Prague he opposed Jan Žižka, when he was blamed for the defeat of the Prague militia at Malešov.

In 1427 he became the vicar of Týn church. He even opposed Sigismund Korybut. In 1429 he became the správcem duchovenstva podobojí, or the Vicar General of the Prague Archbishopric. In 1430 he earned his Master of Arts, and in 1435 became rector of Charles University.

On October 4, 1441 he convened an assembly of all estates at Kutná Hora, where the fundamentals of Hussite belief were laid down as the law of the land. In the year 1442 he made his peace with Jan Příbram. In 1444, the courts found in favour of him against the Taborites, who still refused to comply with the unanimous policy and the Tabor doctrine was decried.

In 1449, he started to correspond regularly with Pope Nicholas V, because he needed to carry out ordinations to the priesthood. In the end, he tried to come to see the Pope in person, but was unable to pass through Germany. For this reason, in 1451 he started talks with Constantinople about the potential cooperation of the Hussite and Greek Churches, but had to give up in 1452, when Constantinople fell to the Ottoman Turks.
