«A spectre is haunting Europe -- the spectre of Communism. All the Powers of old Europe have entered into a holy alliance to exorcise this spectre: Pope and Czar, Metternich and Guizot, French Radicals and German policespies...» The Manifesto of the Communist Party is an 1848 political pamphlet by German philosophers Karl Marx and Friedrich Engels. Commissioned by the Communist League and originally published in London (in the German language as Manifest der kommunistischen Partei) just as the revolutions of 1848 began to erupt, the Manifesto was later recognised as one of the world's most influential political manuscripts. It presents an analytical approach to the class struggle (historical and present) and the problems of capitalism and the capitalist mode of production, rather than a prediction of communism's potential future forms.
The Communist Manifesto summarises Marx and Engels' theories about the nature of society and politics, that in their own words, "The history of all hitherto existing society is the history of class struggles".
«I mean to inquire if, in the civil order, there can be any sure and legitimate rule of administration, men being taken as they are and laws as they might be...» The Social Contract, or Principles of Political Right by Jean-Jacques Rousseau is a book in which Rousseau theorized about the best way to establish a political community in the face of the problems of commercial society, which he had already identified in his Discourse on Inequality (1754).
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; as Rousseau asserts, only the people, who are sovereign, have that all-powerful right.
The stated aim of The Social Contract is to determine whether there can be a legitimate political authority, since people's interactions he saw at his time seemed to put them in a state far worse than the good one they were at the state of nature, even though living in isolation.
