The least powerful form of government system for the state is a confederal system. In a confederal system, power is primarily held by the individual states or regional governments, and the central government has limited authority. The central government's powers are typically limited to issues such as defense or foreign affairs, while most key decisions and policies are determined by the individual states or regions.
The government system in which the state is given the least power is a unitary system. In a unitary system, the central or national government holds the majority of the power, while local or regional governments have limited or delegated powers. These powers can be altered or revoked by the central government at any time. Examples of countries with unitary systems include France, Japan, and the United Kingdom.
