Republic

A republic (from Latin: res publica) is a sovereign state or country which is organised with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic is commonly limited to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names.

Both modern and ancient republics vary widely in their ideology and composition. In the classical and medieval period of Europe, many states were fashioned on the Roman Republic, which referred to the governance of the city of Rome, between it having kings and emperors. The Italian medieval and Renaissance political tradition, today referred to as "civic humanism", is sometimes considered to derive directly from Roman republicans such as Sallust and Tacitus. However, Greek-influenced Roman authors, such as Polybius and Cicero, sometimes also used the term as a translation for the Greek politeia which could mean regime generally, but could also be applied to certain specific types of regime which did not exactly correspond to that of the Roman Republic. Republics were not equated with classical democracies such as Athens, but had a democratic aspect.

Republic (Plato)

The Republic (Greek: Πολιτεία, Politeia; Latin: De Republica) is a Socratic dialogue, written by Plato around 380 BC, concerning the definition of justice (δικαιοσύνη), the order and character of the just city-state and the just man—for this reason, ancient readers used the name On Justice as an alternative title (not to be confused with the spurious dialogue also titled On Justice). The dramatic date of the dialogue has been much debated and though it might have taken place some time during the Peloponnesian War, "there would be jarring anachronisms if any of the candidate specific dates between 432 and 404 were assigned". Plato's best-known work, it has proven to be one of the world's most influential works of philosophy and political theory, both intellectually and historically. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city called Kallipolis (Καλλίπολις), which is ruled by philosopher-kings; and by examining the nature of existing regimes. The participants also discuss the theory of forms, the immortality of the soul, and the roles of the philosopher and of poetry in society.
