Conquest Law and Legal Definition

In International law, conquest refers to an act of force by which, during a war, a belligerent occupies territory within an enemy country with the intention of extending its sovereignty over that territory. The intention to do so is explained in a proclamation or some other legal act. It is a general rule that where conquered countries have laws of their own, these laws remain in force after the conquest.

In history, conquest refers to the acquisition of land by any method other than descent, especially by purchase. The land so acquired is also called conquest.
