Transitions between modes of production

I posted this is r/communism101 , but after a day I had no responses. Maybe I’ll have better luck here. If this is an inappropriate place for this let me know and I’ll delete.My understand of the modes of production is as follows: (Brief descriptions)Primitive/proto-communism: everything before the development of class. Communal “ownership” of land and productive forces.Ancient mode: slavery based production. (From my reading of The German Ideology, I believe at first, slaves were communally owned? Not so clear here)Feudal mode: peasant class labours and gives a due to the land-owning nobility. (I think this was mostly in rural areas, while in cities there were journeymen and artisans which led to the development of guilds?)Capitalist mode: establishment of the bourgeoisie and the proletariat. Capital is used to further accumulation of wealth. Labour-power is sold by proletariat to capitalists to survive.Communism: class distinctions have withered away and productive forces are held in common. Differing from Proto-communism in its post-scarcity.What I’m looking for is something to read about the transition between these modes. As I understand it, there is a mode and antagonism between classes leads to a new mode, so on and so forth. I’m trying to find a detailed Marxist historical account for this.I’m reading the German Ideology and marx seems to be doing just that in his description of the modes of production, but it is not completely clear to me, and some of the pieces in between modes are unclear.Any help is appreciated. via /r/communism https://ift.tt/32TXeCZ
