Removing someone from power by force, or throwing something over or across something else; present participle of 'overthrow'.
From Old English 'over-' (across, beyond) + 'thrawan' (to throw). Germanic roots; parallel to Old Saxon 'thrawan' and Old High German 'drawan'. Used since medieval times for violent removal of rulers.
Many governments have fallen through 'overthrowing' the existing regime, but the word itself is physically violent in origin—you're literally throwing something over. Metaphorically hurling the king off his throne.
