We study 't Hooft's integral equation determining the meson masses Mn in multicolor QCD2. In this paper we concentrate on developing an analytic method, and restrict our attention to the special case of quark masses . Among our results is the systematic large-n expansion, and exact sum rules for Mn. Although we explicitly discuss only the special case, the method applies to the general case of quark masses, and we announce some preliminary results for m1 = m2 (equations (6.1) and (6.3)).
