We study two-dimensional gauge theories with fundamental fermions and a general first-order gauge-field lagrangian. For the case of U(1) we show how standard bosonization of the Schwinger model generalizes to give mesons interacting through a general Landau-Ginzburg potential. We then show how for the case of SU(N) 't Hooft's solution of large-N two-dimensional QCD can be generalized in a consistent and natural manner. We finally point out the possible relevance of studying these theories to the string formulation of two-dimensional QCD as well as to understanding QCD in higher dimensions. © 1994.
