Southern wedge of the country of Bosnia and Herzegovina. Represents a geographic and historic entity, not an administrative unit.
"The rugged landscape of Herzegovina forms a distinct southern wedge within Bosnia and Herzegovina, preserving its historic identity separate from modern administrative divisions."
The name Herzegovina comes directly from Serbo-Croatian, where it originally meant "a duke's possession." This term was formed by combining the German word for duke with local possessive and feminine endings to describe the territory ruled by that leader.
