The Holy Family (German: "Die heilige Familie" ) is a book written by Karl Marx and Friedrich Engels in November 1844.
 The book is a critique of the Young Hegelians and their trend of thought which was very popular in academic circles at the time.
 The title was a suggestion by the publisher and is meant as a sarcastic reference to the Bauer Brothers and their supporters.
 The book created a controversy with much of the press and caused Bruno Bauer to attempt to refute the book in an article which was published in "Wigand's Vierteljahrsschrift" in 1845.
 Bauer claimed that Marx and Engels misunderstood what he was trying to say.
 Marx later replied to his response with his own article that was published in the journal "Gesellschaftsspiegel" in January 1846.
 Marx also discussed the argument in chapter 2 of "The German Ideology".
Eduard Bernstein (6 January 185018 December 1932) was a German social-democratic political theorist and politician, a member of the Social Democratic Party (SPD), and the founder of evolutionary socialism, social democracy, and reformism.
 Bernstein had held close association to Karl Marx and Friedrich Engels, but he saw flaws in Marxist thinking and began to criticize views held by Marxism when he investigated and challenged the Marxist materialist theory of history.
 He rejected significant parts of Marxist theory that were based upon Hegelian metaphysics; he rejected the Hegelian dialectical perspective.
Anti-Dühring (German: "Herrn Eugen Dührings Umwälzung der Wissenschaft" , "Herr Eugen Dühring's Revolution in Science") is a book by Friedrich Engels, first published in German in 1878.
 It had previously been serialised in a periodical.
 There were two further German editions in Engels' lifetime.
 "Anti-Dühring" was first published in English translation in 1907.
Principles of Communism (German: "Grundsätze des Kommunismus") is a book written in 1847 by Friedrich Engels, the co-founder of Marxism.
 It is structured as a catechism, containing 25 questions about communism, which Engels provides an answer to.
 Engels explains the basics of communism, and discusses society, history, and economic systems from a Marxist point of view, with the materialist conception of history in focus.
 It was used as a base for the writing of the longer "Manifesto of the Communist Party".
The history of socialism has its origins in the French Revolution of 1789 and the changes which it wrought, although it has precedents in earlier movements and ideas.
 The Communist Manifesto was written by Karl Marx and Friedrich Engels in 1848 just before the Revolutions of 1848 swept Europe, expressing what they termed 'scientific socialism'.
 In the last third of the 19th century in Europe social democratic parties ar
Socialism: Utopian and Scientific (German: "Die Entwicklung des Sozialismus von der Utopie zur Wissenschaft" ) is a book written in 1880 by co-founder of Marxism Friedrich Engels, primarily extracted from his earlier book "Anti-Dühring", particularly from the introduction and Part 3, Chapter 2.
 It was first published in France in 1880.
 The title "Socialism: Utopian and Scientific" was adopted for the English publication in 1892.
The Friedrich Engels Guards Regiment (also known as NVA Guard Regiment 1) was a special guard unit of the East German National People's Army (NVA).
 The regiment was named after Friedrich Engels, the German socialist that collaborated with Karl Marx in systematizing Marxism.
Scientific socialism is the term first used by Friedrich Engels to describe the social-political-economic theory first pioneered by Karl Marx.
 The purported reason why this form of socialism is "scientific socialism" (as opposed to "utopian socialism") is that it is said to be based on the scientific method, in that its theories are held to an empirical standard, observations are essential to its development, and these can result in changes and/or falsification of elements of the theory.
The Condition of the Working Class in England (German: "Die Lage der arbeitenden Klasse in England") is an 1845 book by the German philosopher Friedrich Engels, a study of the industrial working class in Victorian England.
 Engels' first book, it was originally written in German as "Die Lage der arbeitenden Klasse in England"; an English translation was published in 1885.
 It was written during Engels's 1842–44 stay in Manchester, the city at the heart of the Industrial Revolution, and compiled from Engels' own observations and detailed contemporary reports.
In Marxist theory a new democratic society will arise through the organised actions of an international working class, enfranchising the entire population, freeing up humans to act without being bound by the labour market.
 In such a utopian world there would also be little if any need for a state, the goal of which was to enforce the alienation.
 Karl Marx and Friedrich Engels stated in the Communist Manifesto and later works that "the first step in the revolution by the working class, is to raise the proletariat to the position of ruling class, to win the battle for democracy" and universal suffrage, being "one of the first and most important tasks of the militant proletariat".
 As Marx wrote in his "Critique of the Gotha Program", "between capitalist and communist society there lies the period of the revolutionary transformation of the one into the other.
 Corresponding to this is also a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat."
 He allowed for the possibility of peaceful transition in some countries with strong democratic institutional structures (such as Britain, the US and the Netherlands), he suggested that in other countries in what workers can not "attain their goal by peaceful means" the "lever of our revolution must be force", stating that the working people had the right to revolt if they were denied political expression.
 In Principles of Communism, in response to the question "What will be the course of this revolution?"
