Ján Havlík (1928–1965) was a Slovak Catholic seminarian who stood as a courageous witness to his faith during a time of intense persecution under the communist regime in Czechoslovakia. Born in the small village of Vysoká nad Uhom, Slovakia, Ján grew up in a devout family that nurtured his strong sense of morality and dedication to the Church. Feeling a deep vocational calling, he entered seminary to study for the priesthood. However, the communist government, which sought to suppress religious expression, targeted seminaries and clergy, making it dangerous to openly live out one’s faith.

In 1951, Ján was arrested by the communist authorities for his involvement in the underground Church and his refusal to renounce his faith. He endured years of imprisonment, facing torture, isolation, and inhumane conditions, yet he remained steadfast in his commitment to Christ. Fellow prisoners recounted Ján's unwavering faith, prayerfulness, and ability to uplift others despite the harsh realities of their situation. His resilience and willingness to suffer for his beliefs inspired those around him, even as his health deteriorated due to the brutal treatment he endured.
