Jan Hus (/hʊs/;Czech: [ˈjan ˈɦus]; c. 1369 – 6 July 1415), often referred to in English as John Hus or John Huss, was a Czech priest, philosopher, early Christian reformer and Master at Charles University in Prague. After John Wycliffe, the theorist of ecclesiastical Reformation, Hus is considered the first Church reformer, as he lived before Luther, Calvin and Zwingli.
Hus was a key predecessor to Protestantism, and his teachings had a strong influence on the states of Western Europe, most immediately in the approval of a reformist Bohemian religious denomination, and, more than a century later, on Martin Luther himself. He was burned at the stake for heresy against the doctrines of the Catholic Church, including those on ecclesiology, the Eucharist, and other theological topics.
After his execution in 1415, the followers of Hus's religious teachings (known as Hussites) rebelled against their Roman Catholic rulers and defeated five consecutive papal crusades between 1420 and 1431 in what became known as the Hussite Wars. A century later, as many as 90% of inhabitants of the Czech lands were non-Catholic and some still followed the teachings of Hus and his successors.
One day I decided
I'd aspire to higher ambition
So I set out on a mission
To change the world
Armed and dangerous with my well-meant words
And best intentions
I went sharing my convictions
With every livin' soul
But it wasn't long 'til the lightning flashed
The storms of disenchantment crashed
And my ambitions were scattered by winds of doubt
And it wasn't long 'til I learned to see
Life wouldn't always be easy for me
