We study the soliton type solutions arising in two-dimensional quantumchromodynamics (QCD$_{2}$). The so-called generalized sine-Gordon model (GSG)arises as the low-energy effective action of bosonized QCD$_{2}$ for unequalquark mass parameters, and it has been shown that the relevant solitonsdescribe the normal and exotic baryonic spectrum of QCD$_{2}$[JHEP(03)(2007)(055)]. In the first part of this chapter we classify thesoliton and kink type solutions of the sl(3) GSG model. Related to the GSGmodel we consider the sl(3) affine Toda model coupled to matter fields (Diracspinors)  (ATM). It has been shown the confinement of the spinors inside the solitonsand kinks of the GSG model providing an extended hadron model for "quark"confinement [JHEP(01)(2007)(027)]. In the second part of this chapter wediscuss the appearance of the constituent quarks in the context of bosonizedQCD$_{2}$ and the relevance of the $sl(2)$ ATM model in order to describe theconfinement of the color degrees of freedom. We have shown that QCD$_{2}$ hasquark soliton solutions if the quark mass is sufficiently large.
