Regional state

A regional state or a regionalised unitary state, is a term used to denote a type of state that is formally unitary but where a high degree of political power has been highly decentralised to regional governments. This contrasts with a state organized on principles of federalism (either a federal republic such as the United States, Brazil, or India or a federal monarchy such as Belgium or Malaysia) where the powers of the regions are enshrined in constitutional law. In many cases, the regions are based on long standing cultural or regional divisions.
