A republic is a system of government where people choose representatives through elections to make decisions in the public's interest. In contrast, a democracy might rely primarily on sortition (e.g. juries) to make decisions by a representative sample of the public while an autocracy concentrates power in very few hands. , 159 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 is the word "republic" used in the names of all states with elected governments.

One of Plato's major works on political science was titled Politeia and in English it is thus known as The Republic. However, apart from the title, in modern translations of The Republic, alternative translations of politeia are also used. However, in Book III of his Politics, Aristotle was apparently the first classical writer to state that the term politeia can be used to refer more specifically to one type of politeia: "When the citizens at large govern for the public good, it is called by the name common to all governments (to koinon onoma pasōn tōn politeiōn), government (politeia)". Also amongst classical Latin, the term "republic" can be used in a general way to refer to any regime, or in a
