Defenestration (from Neo-Latin  ) is the act of throwing someone or something out of a window.
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. The word comes from the Neo-Latin de- (down from) and fenestra (window or opening).

By extension, the term is also used to describe the forcible or peremptory removal of an adversary.

Origin 
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. 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.

After negotiations between the parties, they agreed to share the government. The patricians did not accept this easily, as it caused them to lose their absolute power. In an attempt to regain absolute control, they had Wouter van der Leyden assassinated in Brussels. Seeking revenge, the crafts handed over the patrician to a furious crowd. The crowd stormed the city hall and defenestrated the patricians. At least 15 patricians were killed during this defenestration of Leuven.

Akbar was woken up in the tumult after the murder. He struck Adham Khan down personally with his fist and immediately ordered his defenestration by royal order. The first time, his legs were broken as a result of the  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. Adham Khan had wrongly counted on the influence of his mother and Akbar's wet nurse, Maham Anga, to save him as she was almost an unofficial regent in the days of Akbar's youth. 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.

Notable autodefenestrations

 In the Acts of the Apostles in the New Testament, the accidental autodefenestration of a young man of Troas named Eutychus is recorded. The Apostle Paul was travelling to Jerusalem and had stopped for seven days in Troas. While Paul was preaching in a third-story room late on a Sunday night to the local assembly of Christian believers, Eutychus drifted off to sleep and fell out of the window in which he was sitting. The text indicates that Eutychus did not survive but was brought back to life after Paul embraced him. ()

In popular culture 
 In his poem Defenestration, R. P. Lister wrote with amusement about the creation of so exalted a word for so basic a concept. The poem narrates the thoughts of a philosopher undergoing defenestration. As he falls, the philosopher considers why there should be a particular word for the experience, when many equally simple concepts do not have specific names. In an evidently ironic commentary on the word, Lister has the philosopher summarize his thoughts with, "I concluded that the incidence of logodaedaly was purely adventitious."
 There is a range of hacker witticisms referring to "defenestration". For example, the term is sometimes used humorously among Linux users to describe the act of removing Microsoft Windows from a computer.
