In politics, the term left wing derives from the French Revolution, as radical Montagnard and Jacobin deputies from the Third Estate generally sat to the left of the president's chair in parliament, a habit which began in the Estates General of 1789. Throughout the 19th century in France, the main line dividing left and right was between supporters of the French Republic and those of the Monarchy.[5] The June Days Uprising during the Second Republic was an attempt by the left to assert itself after the 1848 Revolution, but only a small portion of the population supported this. In the mid-19th century, nationalism, socialism, democracy, and anti-clericalism became features of the French Left. After Napoleon III's 1851 coup and the subsequent establishment of the Second Empire, Marxism began to rival radical republicanism and utopian socialism as a force within left-wing politics. The influential Communist Manifesto by Karl Marx and Friedrich Engels, published in 1848, asserted that all human history is the history of class struggle. They predicted that a proletarian revolution would eventually overthrow bourgeois capitalism and create a classless, stateless, post-monetary society.
