We exhibit static solutions of QCD in two dimensions that have the quantum numbers of baryons and mesons, constructed out of quark and anti-quark solitons of the bosonized Lagrangian. In isolation the latter solitons have infinite energy, corresponding to the presence of a string carrying the non-singlet color flux off to spatial infinity. When [ital N][sub [ital c]] solitons of this type are combined, a static, finite-energy, color singlet solution is formed, corresponding to a baryon. Similarly, static meson solutions are formed out of a soliton and an anti-soliton of different flavors. The stability of the mesons against annihilation is ensured by flavor conservation. Our results can be viewed as a derivation of the constituent quark model in QCD[sub 2], allowing a detailed study of constituent mass generation and of the heavy quark symmetry.
