What is extending the nations boundaries?

Extending a nation's boundaries refers to the process of expanding a country's territorial limits, often through methods such as military conquest, colonization, or diplomatic negotiation. This can involve acquiring new land, integrating territories inhabited by people of the same nation, or asserting control over disputed regions. Historically, such actions have been motivated by economic, strategic, or ideological reasons, but they can also lead to conflicts and tensions with neighboring states or indigenous populations.
