Constitutional government

Ancient

Aristotle (c. 350 BC) was the first to make a formal distinction between ordinary law and constitutional law, establishing ideas of constitution and constitutionalism, and attempting to classify different forms of constitutional government. The most basic definition he used to describe a constitution in general terms was "the arrangement of the offices in a state". In his works Constitution of Athens, Politics, and Nicomachean Ethics, he explores different constitutions of his day, including those of Athens, Sparta, and Carthage. He classified both what he regarded as good and what he regarded as bad constitutions, and came to the conclusion that the best constitution was a mixed system including monarchic, aristocratic, and democratic elements. He also distinguished between citizens, who had the right to participate in the state, and non-citizens and slaves, who did not.
