I’m wondering how modern historians would view and respond to the Marxian theory of history.
There's always more that can be said, but you might also appreciate some of these earlier answers.
What does Marxist historiography consist of, and what are its problems? with /u/ThucydidesWasAwesome.
Marxist historical analyses of the Holocaust. from /u/commiespaceinvader who adds some important context on Marxist perspectives.
A Monday Methods: Marxism and Hegemony
and Monday Methods: In honor of this week's theme, a closer look at E.P. Thompson and the Making of the English Working Class. Again, not quite a direct answer but adds some important context.
Both last ones are also by Commiespaceinvader.
