Definitions of the major governmental terms are as follows. (Note that for some countries more than one definition applies.):
Absolute monarchy - a form of government where the monarch rules unhindered, i.e., without any laws, constitution, or legally organized opposition.
Authoritarian - a form of government in which state authority is imposed onto many aspects of citizens' lives.
Commonwealth - a nation, state, or other political entity founded on law and united by a compact of the people for the common good.
Communist - a system of government in which the state plans and controls the economy and a single - often authoritarian - party holds power; state controls are imposed with the elimination of private ownership of property or capital while claiming to make progress toward a higher social order in which all goods are equally shared by the people (i.e., a classless society).
Constitutional - a government by or operating under an authoritative document (constitution) that sets forth the system of fundamental laws and principles that determines the nature, functions, and limits of that government.
Constitutional democracy - a form of government in which the sovereign power of the people is spelled out in a governing constitution.
Constitutional monarchy - a system of government in which a monarch is guided by a constitution whereby his/her rights, duties, and responsibilities are spelled out in written law or by custom.
Democracy - a form of government in which the supreme power is retained by the people, but which is usually exercised indirectly through a system of representation and delegated authority periodically renewed.
Democratic republic - a state in which the supreme power rests in the body of citizens entitled to vote for officers and representatives responsible to them.
Dictatorship - a form of government in which a ruler or small clique wield absolute power (not restricted by a constitution or laws).
Ecclesiastical - a government administrated by a church.
Federal (Federation) - a form of government in which sovereign power is formally divided - usually by means of a constitution - between a central authority and a number of constituent regions (states, colonies, or provinces) so that each region retains some management of its internal affairs; differs from a confederacy in that the central government exerts influence directly upon both individuals as well as upon the regional units.
Federal republic - a state in which the powers of the central government are restricted and in which the component parts (states, colonies, or provinces) retain a degree of self-government; ultimate sovereign power rests with the voters who chose their governmental representatives.
Islamic republic - a particular form of government adopted by some Muslim states; although such a state is, in theory, a theocracy, it remains a republic, but its laws are required to be compatible with the laws of Islam.
Monarchy - a government in which the supreme power is lodged in the hands of a monarch who reigns over a state or territory, usually for life and by hereditary right; the monarch may be either a sole absolute ruler or a sovereign - such as a king, queen, or prince - with constitutionally limited authority.
Parliamentary democracy - a political system in which the legislature (parliament) selects the government - a prime minister, premier, or chancellor along with the cabinet ministers - according to party strength as expressed in elections; by this system, the government acquires a dual responsibility: to the people as well as to the parliament.
Parliamentary government (Cabinet-Parliamentary government) - a government in which members of an executive branch (the cabinet and its leader - a prime minister, premier, or chancellor) are nominated to their positions by a legislature or parliament, and are directly responsible to it; this type of government can be dissolved at will by the parliament (legislature) by means of a no confidence vote or the leader of the cabinet may dissolve the parliament if it can no longer function.
Parliamentary monarchy - a state headed by a monarch who is not actively involved in policy formation or implementation (i.e., the exercise of sovereign powers by a monarch in a ceremonial capacity); true governmental leadership is carried out by a cabinet and its head - a prime minister, premier, or chancellor - who are drawn from a legislature (parliament).
Presidential - a system of government where the executive branch exists separately from a legislature (to which it is generally not accountable).
