Which system of government is not defined by a goegraphic distribution of power?

A system of government not defined by a geographic distribution of power is a unitary system. In a unitary system, power is centralized in a single national government, which holds the authority to create or dissolve local governments. This contrasts with federal systems, where power is divided between national and regional authorities. In a unitary system, local governments primarily execute the directives of the central authority rather than having autonomous powers.
