WebEinstein-Cartan theory (c.1922 and 1928) is Einstein's theory of general relativity, extended to include fermions. Einstein's GR is written in the language of tensors, designed to be invariant under general coordinate transformations. By contrast, Einstein-Cartan is written with tensors and spinors, and so additionally has local Lorentz covariance.
