frontier expansion

Settling new territories

Frontier expansion is the process of extending a nation's settled territory into lands considered undeveloped or sparsely populated.

The term carries the perspective of the expanding power—what's a frontier to settlers may be homeland to indigenous peoples.

In American history, frontier expansion describes the westward movement across the continent: Frontier expansion accelerated after the Civil War.

The phrase applies to any territorial growth into borderlands.
