Defenstration is kinda historic habit in my country. There are even some jokes in popular culture about them.

Thought that this was only a thing in Portugal.

Nice to learn that it has a meaning all over europe!
In Portugal's case (from wikipedia):
Miguel de Vasconcelos (or
Vasconcellos)
e Brito (c. 1590 -
Lisbon, 1 December 1640; Portuguese pronunciation:
[miˈɡɛɫ dɨ vaʃkõˈsɛluʃ]) was the last
Secretary of State (Prime Minister) of the
Kingdom of Portugal, during the
Philippine Dynasty, in which both kingdoms of Portugal and Spain remained separated but united by the same king and foreign policy.
He was in office from 1635 to 1640, serving under
Margarida of Savoy, Vicereine of Portugal, the
Duchess of Mantua, a cousin of
King Philip III.
He was probably the most hated collaborator with the Spanish, considered a traitor during the last years of the Philippine Dynasty, especially after the revolts of 1637. On the morning of 1 December 1640, a group of Portuguese noblemen who wanted to restore full independence started a revolution, immediately supported by the people of
Lisbon. After entering the palace, the conspirators sought Miguel Vasconcelos, but saw no sign of him. They would eventually find Miguel de Vasconcelos hidden in a closet with a gun. His movements within the small closet and the rustling of papers inside gave away his position. He was shot to death and
defenestrated, leaving his corpse to the angry public.
