<P> The term tripartite system is commonly ascribed to French Enlightenment political philosopher Baron de Montesquieu , although he did not use such a term . In reality he referred to `` distribution '' of powers . In The Spirit of the Laws ( 1748 ) , Montesquieu described the various forms of distribution of political power among a legislature , an executive , and a judiciary . Montesquieu 's approach was to present and defend a form of government which was not excessively centralized in all its powers to a single monarch or similar ruler , form of government known then as `` aristocracy '' . He based this model on the Constitution of the Roman Republic and the British constitutional system . Montesquieu took the view that the Roman Republic had powers separated so that no one could usurp complete power . In the British constitutional system , Montesquieu discerned a separation of powers among the monarch , Parliament , and the courts of law . </P>
