The term defenestration means throwing someone out of the window (literally). When applied to this particular event, it means political dissent. Hope this helps.

Here is why it was a \"throwing out of window\" event: The Second Defenestration of Prague was an event central to the initiation of the Thirty Years\' War in 1618. The Bohemian aristocracy was effectively in revolt following the election of Ferdinand, Duke of Styria and a Catholic zealot, to rule the Holy Roman Empire, which included Bohemia. At Prague Castle on May 23, 1618, a number of them took two Imperial governors and a scribe and threw them out of the castle windows; they landed in some manure, and none of them were severely injured.

What you need here is not a translation of "defenestration," but of "Prague Defenestration" as a unit, to fit the sentence. The phrase may have its interesting historical dimension, which the reader may or may not appreciate, but that is not your problem. The problem before you is how to fit this phrase in this sentence.

In Arab history, there was a time when الإلقاء من شاهق was a form of punishment that was considered particularly humiliating (as well as painful and deadly). But it did not have to be from a window. Also, defenestration does not necessarily have to be from an upper floor, although in the Prague Defenestration, it was. Also, defenestration is not necessarily intended to be lethal or seriously injurious.
