Defenestration 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. The word comes from the Latin de- (down or away from) and fenestra (window or opening). Likewise, it can also refer to the condition of being thrown out of a window, as in "The Defenestration of Ermintrude Inch".
While the act of defenestration connotes the forcible or peremptory removal of an adversary, and the term is sometimes used in just that sense, it also suggests breaking the windows in the process (de- also means removal). Although defenestrations can be fatal due to the height of the window through which a person is thrown or throws oneself or due to lacerations from broken glass, the act of defenestration need not carry the intent or result of death.
Origin of the term 
The term originates from two incidents in history, both occurring in Prague. In 1419, seven town officials were thrown from the Town Hall, precipitating the Hussite War. In 1618, two Imperial governors and their secretary were tossed from Prague Castle, sparking the Thirty Years War. These incidents, particularly in 1618, were referred to as the Defenestrations of Prague and gave rise to the term and the concept.

Historically, the word defenestration referred to an act of political dissent. Notably, the Defenestrations of Prague in 1419 and 1618 helped to trigger prolonged conflict within Bohemia and beyond. Some Catholics ascribed the survival of those defenestrated at Prague Castle in 1618 to divine intervention.

Trying to turn the tide, they had Wouter van der Leyden assassinated in Brussels. The crafts wanted revenge. They handed over the patrician to a furious crowd. The crowd stormed the city hall and threw the patricians out of the window. At least 15 patricians were killed during this defenestration of Leuven.

Self-defenestration (jumping out of a window) 
Self-defenestration (autodefenestration) is the act of jumping, propelling oneself, or causing oneself to fall, out of a window. This phenomenon played a notable role in such events as the Triangle Shirtwaist fire, 9/11, and other disasters. In December of 1840, Abraham Lincoln and 4 other Illinois legislators jumped out of a window in a political maneuver designed to prevent a quorum on a vote that would have eliminated the Illinois State Bank.
Self-defenestration is also a method of suicide. In the United States, self-defenestration is among the least common methods of committing suicide (typically less than 2% of all reported suicides in the United States for 2005).
In Hong Kong, jumping is the most common method (from any location) of committing suicide, accounting for 52.1% of all reported suicide cases in 2006, and similar rates for the years prior to that. The Centre for Suicide Research and Prevention of the University of Hong Kong believes that it may be due to the abundance of easily accessible high-rise buildings in Hong Kong (implying that much of the jumping is out of windows or from roof tops).
In literature 
In his poem Defenestration, R.P. Lister wrote with amusement over 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 don't 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."
In Jennifer Paynter's Mary Bennet, a young Mary, enraged by George Rovere's insulting mutterings about her poor vision, and his spying on her sister Elizabeth and Mr Coates kissing, she was tempted to push him from the open schoolroom window of Netherfield.
There is a range of hacker witticisms referring to "defenestration". For example, the term is sometimes used humorously among GNU/Linux users to describe the act of removing Microsoft Windows from a computer.
