Born in 1632 in the Dutch Republic, the rationalist philosopher Baruch Spinoza was one of the great fathers of Enlightenment thinking. As Hamid Alizadeh explains, Spinoza’s philosophy – which contained a materialist and atheistic kernel – represented a revolutionary challenge to the authority of both Church and state.

In the 1960s, especially in radical student circles, there were many fanciful ideas floating about. The most pernicious and erroneous of these was the view represented by Herbert Marcuse, Theodor Adorno and Max Horkheimer, that “neo-capitalism” had evolved ways of avoiding capitalist crisis, and that the working class had been integrated into the system as passive consumers in the “affluent” society. As Daniel Morley explains, these were the pseudo-Marxist ideas of the so-called Frankfurt School.

Promoted by some activists as a means of combating oppression, identity politics is increasingly being used by the establishment to attack the left and the labour movement. Workers and youth must fight back with revolutionary class struggle.

Today is the 175th anniversary of the publication of that founding document of the Marxist movement, the Communist Manifesto. Written in 1847 by Marx and Engels, and published the following year, the Manifesto retains an astonishing vitality today. Indeed, it is more relevant now than when it was written. We publish below an article by Trotsky written in 1937 on the occasion of the Manifesto's 90th anniversary.

The American Civil War is an event of world-historic significance. This revolutionary war, which consumed US society for four long and bloody years, overthrew slavery as a mode of exploitation and laid the ground for the rapid development of US capitalism. This episode in the class struggle graphically demonstrated the dynamics of revolution, and should be studied by all class-conscious workers and youth.

90 years ago, on 30 January 1933, Adolf Hitler was appointed chancellor of Germany, paving the way for the dictatorship of the Nazis. In this extract, Ted Grant analyses and explains the events that enabled the fascists to come to power.

We are very happy to share the recollections of a member of our French organisation (Révolution), who was born in Moscow in the 1960s, and later moved to Paris, joining the PCF (Communist Party of France) and eventually the IMT. There, he discovered Trotsky’s writings, which accurately reflected the comrade’s experiences of the bureaucratic regime in the USSR. This is a fascinating insight into what life was really like in the USSR (both good and bad),

In the course of his life, Lenin made several visits to London. The first and longest took place in 1902, and lasted for over a year. He made other visits to attend the congresses of the Russian Social Democratic Labour Party (RSDLP) in 1903, 1905 and 1907, and he returned again in 1908 and 1911 to undertake studies at the British Museum. As of late, there has been a growing interest in retracing Lenin’s footsteps across the city. A fascinating ‘cottage industry’ has grown up around this subject, even encompassing Lenin Walks in the British capital.

Today marks one hundred years since French troops invaded the Ruhr. This occupation, combined with hyperinflation, sparked revolutionary convulsions across Germany. With crisis once again haunting Europe, Rob Sewell examines the lessons of 1923.

This year’s New Year edition of Der Spiegel features an interesting piece titled, “Was Marx right after all?” Full of astute observations about the state of capitalism, it’s a piece symptomatic of the anxiety of the ruling class. But the ‘solutions’ it proposes – reactionary and utopian ideas based on keeping capitalism intact, like ‘degrowth’ and Keynesianism – are really no solutions at all.

So-called left activists, even some self-described Marxists, often exclaim with despair and frustration: "look at how terrible things are, why hasn't there been a revolution yet?" As Alan Woods explains in this article, those who ask such questions have no understanding of the consciousness of the masses, nor of the dialectical method, which Marxists use to penetrate below the superficial surface appearance of society, to the growing tension underneath. This article, which originally appeared in issue 37 of In Defence of Marxism magazine in March 2022 (buy and subscribe here), provides an excellent analysis of the world situation, and

Vast quantities of arms have been poured into Ukraine from the West following Russia’s invasion in February. Even beforehand, NATO and the US provided the Ukrainian Army with a considerable amount of weapons and training.

Interest in the ideas of Leon Trotsky is growing, as workers and youth look for a revolutionary solution to capitalism’s crises. But some on the left have muddied the waters in regards to ‘Trotskyism’. It is important we set the record straight.

For a century, the ruling class has produced industrial quantities of lies and distortions about Lenin, the leader of the Bolshevik Party and of the October Revolution of 1917. This article, therefore, sheds an important light on the life of this revolutionary giant. Covering the formative years of Lenin’s life, the following article – first published in issue 36 of In defence of Marxism magazine, gives a portrait of Lenin in his youth: from his boyhood years, to his making as a revolutionary, the founding of Iskra up until the eve of the second congress of the Russian Social Democratic Labour Party, out of which the Bolshevik

Forty-two years ago this week, South Korea was engulfed in the flames of class struggle. Amidst the fight by the masses for democracy and to bring down the military, a heroic episode took place in Gwangju – a city of nearly one million people. The workers beat back a vicious military, and for a few days the working class de facto took over the running of the city, which was briefly under the control of armed workers’ militias.
