What is the geographic term for a political boundary that is imposed on the landscape by an outside or conquering power, often disregarding the existing cultural, ethnic, or linguistic patterns of the region?

💡 Explanation:

A superimposed boundary is established by a conquering or colonizing power after the settlement pattern has already been established, but it intentionally or unintentionally ignores the pre-existing cultural, ethnic, or religious divisions of the population (a common example is the arbitrary straight-line borders created in Africa by European colonizers).
