We discuss the various phases of two-dimensional QCD/sub 2/(N/sub c/). In the weak-coupling regime (N/sub c/..-->..infinity, g/sup 2/N/sub C/ = const, and g/N/sub c/ = -(g/sup 2/N/sub c//(12..pi..))/sup 1//sup ///sup 2/. We also determine the other important vacuum characteristic: the gluon condensate which is equal to /N/sup 2//sub c/ = -(1/6)g/sup 2/N/sub c/. We explicitly show the absence of a chiral condensate in the strong-coupling regime (g>>m/sub q/), which is in agreement with the Coleman theorem.
