Du contrat social

The Social Contract, originally published as On the Social Contract; or, Principles of Political Right (French: Du contrat social; ou, Principes du droit politique), is a 1762 French-language book by the Genevan philosopher Jean-Jacques Rousseau. The book theorizes about the best way to establish a political community in the face of the problems of commercial society, which Rousseau had already identified in his Discourse on Inequality (1755).

The Social Contract helped inspire political reforms or revolutions in Europe, especially in France. The Social Contract argued against the idea that monarchs were divinely empowered to legislate. Rousseau asserts that only the people, who are sovereign, have that all-powerful right. (Source: Wikipedia)
