Republic Law and Legal Definition

Republic is a system of government in which the people hold sovereign power and elect representatives who exercise that power. The word "republic" is derived from the Latin phrase res publica, which can be translated as "a public affair". The most common definition of a republic is a state without a monarch.

In presidential republics the head of state is also the head of government. U.S was the first example of such a system. In parliamentary systems the head of government, most often titled prime minister, exercises the most real political power and the president's role is almost purely ceremonial and apolitical. For example, India .Semi-presidential systems have a president as an active head of state, but also have a head of government with important powers.
