During the time that he lived at 38 Rue Vaneau in Paris (from October 1843 until January 1845), Marx engaged in an intensive study of political economy (Adam Smith, David Ricardo, James Mill, "etc.")"," the French socialists (especially Claude Henri St. Simon and Charles Fourier) and the history of France. The study of political economy is a study that Marx would pursue for the rest of his life and would result in his major economic workthe three-volume series called "Das Kapital". Marxism is based in large part on three influences: Hegel's dialectics, French utopian socialism and English economics. Together with his earlier study of Hegel's dialectics, the studying that Marx did during this time in Paris meant that all major components of "Marxism" were in place by the autumn of 1844. Marx was constantly being pulled away from his study of political economynot only by the usual daily demands of the time, but additionally by editing a radical newspaper and later by organising and directing the efforts of a political party during years of potentially revolutionary popular uprisings of the citizenry. Still Marx was always drawn back to his economic studies: he sought "to understand the inner workings of capitalism".
