Can you link Spartacus to communism?

You can see the link from two different angles:

On one side, the communist theorists themselves saw Spartacus as a forefather and used the myth of Spartacus as part of their own public myths. This has to do with the way communist thinkers (Marx, Engels etc.) saw history as a never-ending conflict between two classes - the haves and the have nots (they called this class struggle). In this, they saw the communist movement of the 19th and 20th century as having the same fundamental role as Spartacus did in Roman Antiquity - both Spartacus and the communists were representatives and leaders of the "oppressed classes". All schools of communism (Leninism, Trotskyism, Maoism, etc.) subscribe to this analysis of history, so you can say that for all communism this link is self-evident.As such, they themselves created a bond between communism and Spartacus. Moreover, in countries where communism was the dominant ideology, Spartacus was used as a public motive, especially in the field of sports, as the (for example, some sporting events were named "Spartakiads", sport clubs were called Spartak eg. Spartak Moscow etc.)

On the other hand, this link is hard to be seen from practitioners of other historical schools - and they would explain this connection as a founding myth or a legitimizing myth. As communism was a radical ideology breaking away from the past, but still requiring historical legitimization, they could only use extremely recent (and thus potentially weak) figures (Lenin, Marx etc.) or ancient images (of which they chose Spartacus as being a low-class radical figure) for the task, even where there was limited overlap in goals.
