A more thorough explanation: The legal English definition of the term “acquisition of territory by the use of force” refers to the act of a state or entity gaining control over a piece of land or territory through the use of military force or coercion, in violation of international law and the principles of sovereignty and territorial integrity. This practice is generally condemned by the international community and is considered illegal under international law, particularly the prohibition on the use of force to acquire territory as enshrined in the United Nations Charter.
Example: The annexation of Crimea by Russia in 2014 is an example of the acquisition of territory by the use of force.
