katakistisia
Katakistisia is a term used in some contexts, particularly in older or specialized literature, to refer to a period of intense and often violent political upheaval or social unrest within a nation or region. It describes a situation where established authorities are challenged or overthrown, leading to widespread disruption, conflict, and fundamental changes in the political landscape. The term implies a significant and often dramatic shift, rather than a gradual evolution or a minor disturbance.
The etymology of katakistisia is believed to stem from Greek roots, suggesting a forceful or sudden descent.
