The Eastern question, a reprint of letters written 1853-1856 dealing with the events of the Crimean War

Karl Heinrich Marx (5 May 1818 - 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary. Marx completed his doctoral thesis, titled The Difference Between the Democritean and Epicurean Philosophy of Nature, in 1841 and submitted it to the University of Jena. He was awarded a Ph.D. in April 1841. In 1844, Marx befriended Friedrich Engels, the German socialist and became a revolutionary communist. Marx's The Poverty of Philosophy was published in 1847. Marx and Engels published ""The Communist Manifesto"", a political pamphlet summarizing their theories about the nature of society and politics, in 1848. One of the most important political documents of the world, this monumental text is highly influential and continues to remain widely read. The first volume, Capital, Volume I, of his magnum opus Capital (Das Kapital) was published in 1867. Marx continued to work on the remaining two volumes which were published after his death by Engels. Capital, Volume II was published in 1885 and Capital, Volume III in 1894. Considered to be his masterwork, Capital has been translated into all the major languages.
