what was proposed by montesquieu in 'the spirit of the laws'
The Spirit of the Laws Montesquieu spent around twenty one years researching and writing De l'esprit des lois, covering a huge range of topics including law, social life and the study of anthropology, and providing more than 3,000 commendations.[4] In this treatise Montesquieu argued that political institutions needed, for their success, to reflect the social and geographical aspects of the particular community. He pleaded for a constitutional system of government with separation of powers, the preservation of legality and civil liberties, and the end of slavery.[4]
