Plato in his book
The Republic (375 BC) divided governments into five basic types (four being existing forms and one being Plato's ideal form, which exists "only in speech"): •
Aristocracy (rule by
law and order, like ideal traditional "benevolent" kingdoms that are not tyrannical) •
Timocracy (rule by honor and duty, like a "benevolent" military; Sparta as an example) •
Oligarchy (rule by wealth and market-based-ethics, like a
laissez-faire capitalist state) •
Democracy (rule by pure
liberty and
equality, like a
free citizen) •
Tyranny (
rule by fear, like a
despot) These five regimes progressively degenerate starting with aristocracy at the top and tyranny at the bottom. In his
Politics, Aristotle elaborates on Plato's five regimes discussing them in relation to the government of one, of the few, and of the many. From this follows the classification of forms of government according to which people have the authority to rule: either one person (an
autocracy, such as monarchy), a select group of people (an aristocracy), or the people as a whole (a democracy, such as a republic).
Thomas Hobbes stated on their classification:
Modern basic political systems According to
Yale professor
Juan José Linz, there a three main types of
political systems today:
democracies,
totalitarian regimes and, sitting between these two,
authoritarian regimes with
hybrid regimes. Another modern classification system includes
monarchies as a standalone entity or as a hybrid system of the main three.
Autocracy An autocracy is a system of government in which supreme
power is concentrated in the hands of one person, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control (except perhaps for the implicit threat of a
coup d'état or mass
insurrection).
Absolute monarchy is a historically prevalent form of autocracy, wherein a
monarch governs as a singular
sovereign with no limitation on
royal prerogative. Most absolute monarchies are
hereditary, however some, notably the
Holy See, are
elected by an
electoral college (such as the
college of cardinals, or
prince-electors). Other forms of autocracy include
tyranny,
despotism, and
dictatorship.
Aristocracy Aristocracy is a form of government that places power in the hands of a small,
elite ruling class, such as a hereditary
nobility or
privileged
caste. This class exercises
minority rule, often as a
landed timocracy, wealthy
plutocracy, or
oligarchy. Many monarchies were aristocracies, although in modern constitutional monarchies, the monarch may have little effective power. The term
aristocracy could also refer to the non-
peasant, non-servant, and non-
city classes in
feudalism.
Democracy '' survey Democracy is a system of government where
citizens exercise power by
voting and
deliberation. In a
direct democracy, the citizenry as a whole directly forms a
participatory governing body and vote directly on each issue. In
indirect democracy, the citizenry governs indirectly through the selection of
representatives or
delegates from among themselves, typically by
election or, less commonly, by
sortition. These select citizens then meet to form a governing body, such as a legislature or
jury. Some governments combine both direct and indirect democratic governance, wherein the citizenry selects representatives to administer day-to-day governance, while also reserving the right to govern directly through
popular initiatives,
referendums (plebiscites), and the
right of recall. In a
constitutional democracy the powers of the majority are exercised within the framework of representative democracy, but the constitution limits
majority rule, usually through the provision by all of certain
universal rights, such as
freedom of speech or
freedom of association.
Republics A republic is a form of government in which the country is considered a "public matter" (), not the private concern or property of the rulers, and where offices of states are subsequently directly or indirectly elected or appointed rather than inherited. The people, or some significant portion of them, have supreme control over the government and where offices of state are elected or chosen by elected people. A common simplified definition of a republic is a government where the head of state is not a monarch.
Montesquieu included both
democracies, where all the people have a share in rule, and
aristocracies or
oligarchies, where only some of the people rule, as republican forms of government. Other terms used to describe different republics include
democratic republic,
parliamentary republic,
semi-presidential republic,
presidential republic,
federal republic,
people's republic, and
Islamic republic.
Federalism Federalism is a political concept in which a
group of members are bound together by
covenant with a governing
representative head. The term "federalism" is also used to describe a system of government in which
sovereignty is constitutionally divided between a central governing authority and constituent political units, variously called states, provinces or otherwise. Federalism is a system based upon democratic principles and institutions in which the power to govern is shared between national and provincial/state governments, creating what is often called a
federation. Proponents are often called
federalists. == Branches ==
