What Happened in the Defenestration of Prague 1618?

By Michael Ferguson

The Defenestration of Prague in 1618 was a pivotal event in the history of the Thirty Years’ War. It was a dramatic incident that took place at Prague Castle, involving the violent ejection of two imperial governors from a window. This event marked the beginning of a series of conflicts that would shape the course of European history for decades to come.

The Background

In the early 17th century, religious tensions were running high in Europe. The Holy Roman Empire, under the rule of Emperor Matthias, comprised predominantly Catholic territories but also included Protestant regions. The Protestant population had been growing and demanding greater religious freedom.

Emperor Matthias sought to appease both Catholics and Protestants by implementing a policy known as the Letter of Majesty, which granted certain rights to Protestants. However, this did not satisfy some Catholic hardliners who opposed any form of religious tolerance.

The Bohemian Revolt

In 1617, Ferdinand II was elected as King of Bohemia. Ferdinand was a devout Catholic and sought to re-Catholicize Bohemia by suppressing Protestantism. This alarmed many Protestant nobles who feared for their religious freedom.

On May 23, 1618, a group of Protestant nobles stormed Prague Castle and confronted two imperial governors appointed by Ferdinand II – Jaroslav Borzita von Martinic and Wilhelm Slavata. The nobles accused them of violating their religious rights and demanded their resignation.

The Defenestration

As tensions escalated, the situation quickly spiraled out of control. In a moment that would become iconic, the Protestant nobles seized Martinic and Slavata and threw them out of a window in Prague Castle’s Bohemian Chancellery building.

This act of defenestration was seen as a direct challenge to the authority of the Holy Roman Empire and a symbolic rejection of Ferdinand II’s rule. Miraculously, both governors survived the fall, but their survival did not quell the significance of the event.

The Aftermath

The Defenestration of Prague 1618 had far-reaching consequences. It triggered a wave of rebellion across Bohemia and ignited the flames of the Thirty Years’ War, which would drag on until 1648.

The conflict drew in various European powers and became a war not only fought over religion but also for political and territorial control. The war caused immense devastation and loss of life throughout Europe.

The Impact

The Defenestration of Prague served as a rallying cry for Protestant forces, who saw it as a symbol of resistance against Catholic oppression. It also solidified Ferdinand II’s determination to suppress Protestantism in his territories.

Ultimately, the Thirty Years’ War resulted in significant political and religious realignments in Europe. The Peace of Westphalia, signed in 1648, brought an end to the war and established new principles for international relations.

  • Religious freedom: The Peace of Westphalia recognized the principle of cuius regio, eius religio (“whose realm, his religion”), giving rulers the power to determine the religion practiced within their territories.
  • Territorial boundaries: The war led to significant territorial changes. France emerged as a dominant power in Europe while Spain’s influence waned.
  • Balance of power: The conflict weakened the Holy Roman Empire and shifted power from central authorities to individual states, setting the stage for future power struggles between nations.

The Defenestration of Prague 1618 was a turning point in European history. It marked the beginning of a long and devastating war that reshaped the political and religious landscape of the continent. The event serves as a reminder of the power of religious tensions and the profound impact they can have on societies.
