In French, the word siege ultimately comes from the Latin word for "seat", which originally meant siege in 1200 in English. In the late 1300s, the siege was known as a "military attack" on a specific target, usually a fortress or city, in order to gain control over it. Then a target that is under siege is said to be under siege. It is unclear when exactly the phrase originated, but it appears to be under siege in the 19th century to discuss historical and contemporary military actions.
