First Defenestration of Prague: A crowd of radical Hussites kill seven members of the Prague city council.

The Defenestrations of Prague were three incidents in the history of Bohemia in which people were defenestrated. Though already existing in Middle French, the word defenestrate is believed to have first been used in English in reference to the episodes in Prague in 1618 when the disgruntled Protestant estates threw two royal governors and their secretary out of a window of the Hradčany Castle and wrote an extensive apologia explaining their action. In the Middle Ages and early modern times, defenestration was not uncommon—the act carried elements of lynching and mob violence in the form of murder committed together.

The Hussites were a Czech proto-Protestant Christian movement influenced by both the Byzantine Rite and John Wycliffe that followed the teachings of reformer Jan Hus, a part of the Bohemian Reformation.

Prague is the capital and largest city of the Czech Republic and the historical capital of Bohemia. Prague, located on the Vltava River, has a population of about 1.4 million, while its metropolitan area is home to approximately 2.3 million people.
