What is a presidential republic government?

A presidential republic government is a form of government in which the nation is considered a "public matter" ("Republic", in Latin means "res publica").

In a presidential republic the first positions of power are not inherited, but are attained through democracy, in which elected individuals represent the citizen body and practise power according to the rule of law under a constitution, including separation of powers with an elected head of state, referred to as a constitutional republic or representative democracy.
