Critique of ideology emerged as a systematic academic topic first in Frankfurt around 1930

Evidence

If one were looking for a common factor on the intellectual left which developed in the philosophy faculty around 1930, then one would have to say that ideology and the critique of ideology became for the first time a systematic topic there, i.e. that connections between ideas, in the broadest sense, and their social base were being examined. — Rolf Wiggershaus, The Frankfurt School, 457 (#corroborates, via linked claim)
