Forty years ago, in the summer of 1980, the working class in Poland made the whole world tremble. A massive strike movement was spreading across the country: several hundred thousand workers launched wildcat strikes in the different towns; it shook the ruling class in Poland and those in other countries.

"The theoretical conclusions of the communists are in no way based on ideas or principles that have been invented, or discovered, by this or that would-be universal reformer.

This perspective could hardly have been more clearly continued by events during the first year of the decade. The first half of the year, despite important social movements like the steel strike in Great Britain, was dominated by the considerable aggravation of inter-imperia­list tension following the invasion of Afgha­nistan. But the second half of the year was marked by an unprecedented intensification of proletarian struggles, which in Poland reached their highest point since the beginning of the historical resurgence of working class strug­gle in 1968.

In Poland, twenty years ago, in the summer of 1980, there began the most important movement of the world proletariat’s struggle since the end of the revolutionary wave, which broke out during World War I and continued until the beginning of the 1920s. In today’s conditions, when the dominant ideology dismisses the idea that the working class even exists, let alone that it can act as a force in defence of its interests, it is essential for revolutionary organisations to remind workers of the most extensive outbreak of working class struggle for almost 80 years.
