Hussites in Poland
At the beginning of the 15th century, many Poles, especially from Silesia - Silesia belonged to the union of the Czech Crown lands - studied or taught at the University of Prague and thus encountered the teachings of Czech reformers every day. Many Poles from Silesia, however, became followers of the teachings of Jan Hus - Silesia had the most partisans of Hussitism, and throughout the Hussite Revolution Silesia was predominantly anti-Hussite.
