What type of government combines both unitary and confederal political systems?

A government that combines both unitary and confederal political systems is often referred to as a federal system. In this structure, authority is divided between a central government and various regional governments, allowing for both centralized decision-making and local autonomy. The central government typically handles national issues, while regional governments manage local matters. This hybrid approach aims to balance the benefits of unity with the advantages of regional self-governance.
