You really are mr Lazy today aren't you dubs.
Ok I'll give you some clues:
Do you think Bureaucratic dictatorship of a managing class a'la Stalin or the various Stalinist regimes based on the USSR is what Marx meant by Dictatorship of the Proletariat?
Marx and Engel's were writing about a historic example called the Paris Commune:
Both Marx and Engels argued that the short-lived Paris Commune, which ran the French capital for three months before being repressed, was an example of the dictatorship of the proletariat. In the 20th century, a socialist revolution in Russia was followed by the victory of a Stalinist clique of rulers who monopolised political power.[5] Other revolutions in China, Vietnam, Cuba[6] and North Korea were subsequently shaped by the USSR's model of a bureaucratic dictatorship,[7] not by the democratic organization of the working class. As a result, the use of the word "dictatorship" to describe the power of an entire class sometimes became confused with its common usage to describe a single ruler.
That's called counter revolution
SOme insight:
In the 1891 postscript to The Civil War in France (1872) pamphlet, Friedrich Engels said: "Well and good, gentlemen, do you want to know what this dictatorship looks like? Look at the Paris Commune. That was the Dictatorship of the Proletariat"; to avoid bourgeois political corruption:
the Commune made use of two infallible expedients. In this first place, it filled all posts — administrative, judicial, and educational — by election on the basis of universal suffrage of all concerned, with the right of the same electors to recall their delegate at any time. And, in the second place, all officials, high or low, were paid only the wages received by other workers. The highest salary paid by the Commune to anyone was 6,000 francs. In this way an effective barrier to place-hunting and careerism was set up, even apart from the binding mandates to delegates [and] to representative bodies, which were also added in profusion.
Moreover he noted that the State is
at best an evil inherited by the proletariat after its victorious struggle for class supremacy, whose worst sides the proletariat, just like the Commune, cannot avoid having to lop off at the earliest possible moment, until such time as a new generation, reared in new and free social conditions, will be able to throw the entire lumber of the state on the scrap-heap.
