Defenestration (from Neo-Latin de fenestrā^[1]) is the act of throwing someone or something out of a window.^[2] The term was coined around the time of an incident in Prague Castle in the year 1618 which became the spark that started the Thirty Years' War. This was done in "good Bohemian style", referring to the defenestration which had occurred in Prague's New Town Hall almost 200 years earlier (July 1419), and on that occasion led to the Hussite war.^[3] The word comes from the Neo-Latin^[4] de- (down from) and fenestra (window or opening).^[5]

By extension, the term is also used to describe the forcible or summary removal of an adversary.^[6]

The term originates from two incidents in history, both occurring in Prague. In 1419, seven town officials were thrown from the New Town Hall, precipitating the Hussite War. In 1618, two Imperial governors and their secretary were tossed from the Prague Castle, sparking the Thirty Years' War.^[7] These incidents, particularly that in 1618, were referred to as the Defenestrations of Prague and gave rise to the term and the concept.

The word itself is derived from Neo-Latin defenestratio; with dē meaning "out" + fenestra meaning "window" + -atio as a suffix indicating an action or process.

The crowd stormed the city hall and defenestrated the patricians. At least 15 patricians were killed.

Bishop Dom Martinho of Zamora was accused of treason by the populace for being Castilian and supporting Antipope Clement VII and was, therefore, defenestrated from one of the bell towers. His corpse was assaulted and dragged to Rossio Square, where it was left to rot and be eaten by dogs, until the populace had enough of its smell and buried it in the square.^[8]

The first time, his legs were broken as a result of the 12-metre (40-foot) fall from the ramparts of Agra Fort but he remained alive. Akbar, in a rare act of cruelty probably exacerbated by his anger at the loss of his favorite general, ordered his defenestration a second time, killing him.

Akbar personally informed Maham Anga of her son's death, to which she famously commented, "You have done well." She died 40 days later of acute depression.^[9]
