There is a whole scale of variants on the line from the unitary centralistically
organized state to the federal state or even confederation. Among the key words denoting
different types of relations between the narrower and wider parts of a state and their
organs are as follows: vassalage, power deconcentration (that is, organizing per narrower
territorial units of organs directly subordinate to the central power), decentralization, the
so-called double line of the local and central organs relations, local self-government,
regionalization and regional self-government, regional state as genus tertium between the
unitary state and the federation, autonomy, federalism, confederalism
