Blood in Bohemia: the Second Defenestration of Prague and the window that changed Europe
The Second Defenestration of Prague is one of the best-known episodes in Czech history, yet the dramatic fall from the windows of Prague Castle was only the beginning. In Blood in Bohemia, a special series of Czechast, journalists Vít Pohanka and Rob Cameron explore how a failed triple murder became the spark that ignited the Thirty Years' War and changed the course of European history.
Few moments in Czech history are as dramatic—or as consequential—as the Second Defenestration of Prague. On the morning of May 23, 1618, a group of Protestant noblemen entered Prague Castle, confronted two royal governors and their secretary, declared them guilty of violating religious freedoms, and threw all three men out of a high castle window. Against all expectations, they survived.
It is one of history's strangest assassination attempts. Yet what followed proved far deadlier than the attack itself. Within months Bohemia was in open revolt against the Habsburg monarchy. Soon much of Europe was engulfed in the Thirty Years' War, one of the bloodiest conflicts the continent had ever experienced.

To understand why a handful of noblemen resorted to such extraordinary violence, it is necessary to look far beyond the events of 1618. For more than two centuries, Bohemia had been shaped by religious conflict. The execution of Jan Hus in 1415, the Hussite Wars, and the emergence of religious movements such as the Utraquists and the Unity of the Brethren had made the Czech lands one of the most religiously diverse regions in Europe. Long before Martin Luther launched the Protestant Reformation in Germany, Bohemia had already developed its own reform movement.
By the end of the sixteenth century Catholics, Lutherans, Calvinists, Utraquists and members of the Unity of the Brethren lived alongside one another with a degree of tolerance that was unusual for the period. That fragile balance, however, depended on political compromise.
The Habsburg rulers of Bohemia remained firmly Catholic, but they also understood that much of the Bohemian nobility belonged to Protestant churches. For decades they accepted a practical coexistence that allowed the kingdom to remain relatively stable despite its religious diversity.
The promise that raised expectations
The compromise reached its high point during the reign of Emperor Rudolf II. In 1609, facing growing political pressure, Rudolf signed the famous Letter of Majesty, guaranteeing broad religious freedoms for the Protestant estates of the Kingdom of Bohemia. For many nobles, it was far more than another royal decree. It represented a solemn promise, confirmed by both the King of Bohemia and the Holy Roman Emperor, that their religious rights would be protected. But political circumstances soon changed.
Rudolf was succeeded by Matthias, and eventually by Ferdinand of Styria, a deeply committed Catholic ruler who had already imposed vigorous Counter-Reformation policies in his hereditary lands. Protestant churches had been closed, pastors expelled and nobles forced to convert or leave. When Ferdinand became King of Bohemia in 1617, many Protestants feared the same fate awaited them.
Those fears intensified after disputes over two Protestant churches in Broumov and Hrob. To Protestant leaders, the closures appeared to violate the guarantees contained in Rudolf's Letter of Majesty. What might have seemed like local administrative disagreements became, in their eyes, evidence that the kingdom's religious settlement was beginning to collapse.
Three men out of a window
The crisis reached its climax on the morning of May 23, 1618. A delegation of Protestant nobles marched into the Old Royal Palace at Prague Castle and confronted the royal governors Vilém Slavata of Chlum and Košumberk and Jaroslav Bořita of Martinice. After a heated exchange, the noblemen pronounced judgment and dragged both governors to one of the windows of the Bohemian Chancellery. One after another, they were thrown out. Their secretary, Filip Fabricius, soon followed.
The fall measured roughly seventeen metres into the castle moat below. By all logic, none of the three men should have survived. Yet all of them did. Catholic contemporaries regarded the escape as nothing short of divine intervention. Protestants offered a rather more earthly explanation, arguing that the moat contained soft soil, rubbish and other debris that broke the impact of the fall. Whatever the reason, the failed assassination quickly acquired an almost mythical status.
As Blood in Bohemia explains, modern historians are able to reconstruct the events with remarkable precision, thanks not only to surviving eyewitness accounts but also to the work of leading scholars such as British historian Peter H. Wilson, whose detailed research provides a minute-by-minute account of the famous defenestration.
The fall that changed Europe
The irony of the Second Defenestration is that the immediate victims survived, while countless others did not. The attack marked the beginning of the Bohemian Revolt against the Habsburgs. Within two years the conflict had spread beyond the Czech lands, drawing in many of Europe's great powers. What began as a political and religious dispute in Prague evolved into the Thirty Years' War, devastating much of Central Europe and causing millions of deaths through warfare, famine and disease. For Bohemia, the consequences proved equally profound.
The defeat of the Protestant estates at the Battle of White Mountain in 1620 transformed the country's political and religious landscape for generations. Many of the men who organised the Defenestration would eventually lose not only their cause but also their lives. Their story continues in the next episode of Blood in Bohemia, devoted to the execution of twenty-seven Czech noblemen, knights and burghers on Prague's Old Town Square in 1621.
A window that still overlooks history
Today visitors to Prague Castle can still see the room where the famous confrontation took place. The windows of the old Bohemian Chancellery remain there, overlooking what was once the castle moat. Standing beside them, it is surprisingly easy to imagine the extraordinary events of that spring morning more than four centuries ago.
The Second Defenestration of Prague remains one of those rare historical moments that is both deeply symbolic and unmistakably human. Three men were thrown from a window and somehow lived to tell the tale. Yet their survival did nothing to prevent catastrophe. Instead, the events of May 1618 became the opening act of one of Europe's greatest tragedies. As Blood in Bohemia demonstrates, history sometimes changes direction not through vast armies or sweeping political reforms, but through a single room, a handful of determined men—and one very famous window.
