And people here pretending history and class struggled began in the fucking Industrial Revolution

I doubt people HERE have problem with that, and libs elswhere cathegorically refuse to even acknowledge class war exist and only use the term "class" in liberal meaning of overall wealth or income instead of the relation to the means of production.

And bourgeois historians are the same.

Marx famously wrote:

The history of all hitherto existing society(2) is the history of class struggles.

With Engels later added as the knowledge about prehistory expanded:

2. That is, all written history. In 1847, the pre-history of society, the social organisation existing previous to recorded history, all but unknown. Since then, August von Haxthausen (1792-1866) discovered common ownership of land in Russia, Georg Ludwig von Maurer proved it to be the social foundation from which all Teutonic races started in history, and, by and by, village communities were found to be, or to have been, the primitive form of society everywhere from India to Ireland. The inner organisation of this primitive communistic society was laid bare, in its typical form, by Lewis Henry Morgan's (1818-1881) crowning discovery of the true nature of the gens and its relation to the tribe. With the dissolution of the primeval communities, society begins to be differentiated into separate and finally antagonistic classes. I have attempted to retrace this dissolution in The Origin of the Family, Private Property, and the State, second edition, Stuttgart, 1886. [Engels, 1888 English Edition and 1890 German Edition (with the last sentence omitted)]

But to admit there was a class struggle in the past would mean admitting the Marx was right and the class struggle is going now too. Parenti have few words about this.
