I had a thought that it feels like the anarchist tendency of affiliating by economic distribution is a concession to Marx. But I could be way off base.
I could probably look this up but I've been reading legal documents and doing legal writing for 10 hours a day all week so my brain is mush.

Arguably Marxism. The manifesto was written in 1848, anarchist communism really only emerged along with anarchism in the 1870s. Though there have been precursors and pioneers like Joseph Déjacque. Anarchists came before Marxists but anarchism came after Marxism sort of thing.
