Of course Marxism begins in the 19th Century
However,
If you look at a broader time frame,
You will realise that Marxism-Leninism achieved very little when it tried to improve the lives of the populace.
One of the Marxist tenets is that economic relations are stronger than cultural ones, the latter being just a superimposed structure, and not the frame of society.
How wrong.
Soviet proletarians became just a new generation of serfs, not unlike those that had thrived in filth during the previous centuries of tsarist regime.
So yeah, culture is so strong that what we have witnessed in the 20th Century under the name of Marxism or Leninism is, in fact, just an expression of Slavism under different economic conditions.
Economy changed from agriculture to industry, yet culture remained the same.
