The light-cone Hamiltonian is derived from the general gauge- and Lorentz-invariant expression for the q{bar q} Green`s function containing confinement via the area law for the Wilson loop. The resulting Hamiltonian contains, in a nonadditive way, contributions from quark and string degrees of freedom. Different limiting dynamic regimes of the system of quarks connected by the string are found. In the limit of no transverse motion, the authors recover `t Hooft`s 1 + 1 QCD Hamiltonian. The correspondence with the rest-frame Hamiltonian spectrum is established. The important notion of the light-cone string, which contributes significantly to the energy momentum, is discussed. 19 refs.
