Past Tense of “overthrow”
The past tense of overthrow is overthrew; the past participle is overthrown.
Why “overthrow” behaves this way
"Overthrow" combines "over-" with "throw"; the throw/threw/thrown conjugation reflects the internal vowel shift typical of Old English strong verbs. The compound's core political sense — violently removing a government or ruler from power — is attested from Middle English onward, growing out of the more general literal sense of throwing something down or knocking it over, a literal sense still preserved today in baseball's "overthrow" (a throw that sails past its target). Political science and history writing distinguish "overthrow" (a forceful, often sudden removal of a government) from related but distinct terms like "impeachment" (a formal legal process) or "resignation" (a voluntary departure), making precise use of "overthrow" matter for accuracy in historical and political writing.
The baseball sense (a fielder's throw sailing over the intended target, such as first base) and the political sense (a coup overthrowing a government) share identical conjugation but occupy completely separate registers of English — one appears in sports commentary, the other in history and political journalism — and it's a good example of how a single strong-verb compound can serve two entirely unrelated fields without any change to its grammar. Chess writing occasionally borrows "overthrow" loosely to describe a dramatic, decisive defeat of an opponent's position, an informal figurative extension distinct from its dominant political and sports senses but drawing on the same core idea of a sudden, complete reversal.
The common confusion
The confusion is between "overthrew" (simple past) and "overthrown" (participle): "the government was overthrew" is a genuine, if less common, error for the correct passive "was overthrown," following the same throw/threw/thrown pattern confusion seen with the base verb.
How it's actually used
"Overthrow" today dominates political and historical writing (a coup, a revolution, or a movement overthrowing a regime) far more than its sports sense, and it almost always appears with a directly stated target — a government, a dictator, a regime — rather than as a standalone intransitive verb. Sports commentary preserves the older, more literal baseball sense of "overthrow" (a throw that sails past its target, allowing base runners to advance), a usage that exists in a completely separate register from the political sense and rarely causes any confusion because context makes the intended field immediately obvious.
Across the tense system
Passive constructions are extremely common with this verb given its political usage: "was overthrown," "has been overthrown," "had been overthrown" all require the participle "overthrown," never "overthrew." Historical writing about the same event often shifts between simple past ("rebels overthrew the government in March") and passive perfect ("the government had been overthrown by spring") depending on whether the narrative centers the actors or the outcome.
Common real mistakes
The recurring error is using "overthrew" in a passive construction where "overthrown" is required ("the dictator was overthrew" instead of "was overthrown"). This is less common than analogous errors with "take" or "see" compounds, but it does appear in less polished historical and political writing. Because political writing about coups and revolutions leans so heavily on the passive voice ("the government was overthrown"), writers should watch specifically for the passive-voice slip "was overthrew," which is less common than some other irregular-verb errors on this list but does appear in less carefully edited news writing. A further nuance worth noting: "overthrow" implies force or abruptness, distinguishing it from a peaceful transfer of power through election or resignation, a distinction historians and journalists are careful to preserve in accurate reporting.
Examples
- Rebels overthrew the government after months of unrest.
- The dictator was overthrown in a swift, largely bloodless coup.
- Historians debate whether the monarchy could have been overthrown sooner.
- The outfielder's wild throw overthrew the cutoff man by thirty feet.
- Colonial forces overthrew the local ruler within a single year.
- The center fielder's throw overthrew home plate by several feet.
- Popular protests preceded the eventual overthrow of the regime.
Memory trick
Same family as "throw": throw, threw, thrown becomes overthrow, overthrew, overthrown — picture a coup as a wild pitch sailing over the intended target, and the "-thrown" spelling sticks.
