I’ve been studying this part of history and cannot find answers even though I’m Czech and therefore able to read Czech sources.
John Huss was born around 1370 and did not become a priest until 1400 when was officially sanctified by the church. Wycliffe died in 1384 when Huss has been just around 14 years old; therefore, he was not aware that Huss existed. Some sources mention that the earliest encounter of Wycliffe ideas within Bohemia could be traced to 1381. The full knowledge about Wycliffe were certainly brought to Prague from England after the marriage of the Queen Anne to Richard II in 1382 when various visitors to the court and the student from English universities introduced Wycliffe ideology to a wider public within the Prague University. Wycliffe had first larger following in Bohemia during the administration of Archbishop Jan z Jenstejna (+1400). They became more prevalent after 1400 when the Church was losing control over the University, which became the main ideological battleground between various reformists and conservatives. Nevertheless, after 1410 some of the previous supporters became the critics of it like Stanislav of Znojmo. This caused an ideological split between Huss and his former colleagues.
The role of Wycliffe ideas upon Huss and the Hussite movement were tremendous, but it is also crucial to mention that within Bohemia, the reform movement started at the end of the Charles IV reign. There were preachers like "Jan" Milic z Kromerize (+1374) and Konrád Waldhauser (+1369). The Hussite movement was influenced from various groups, it did not appear suddenly, and many of its followers did find inspiration in Wycliffe. John Huss was one of the many within the Bohemian society, that were dissatisfied with the ongoing social, economic, ideological, and political crisis within Bohemia. The radicalization was an answer to deepening turmoil when the late Bohemian kingdom was in is crossroad.
