John Hus, his life, work, and conflicts are recounted in this article, with the circumstances that lead him to martyrdom at the stake on July 6, 1415, six centuries ago. His work galvanized Bohemia and contributed to the identity of the Czech nation and places him in the gallery of those who were precursors of the Reformation, such as Waldo and Wycliffe. Some comparisons are drawn between Hus and Luther, who were both passionate for the truth. They desired it, sought it, and wanted to unearth it wherever it was buried by centuries of human tradition. It was the light that did not leave them even in the darkest night. No other consideration could obstruct them, even though their lives were at stake.
