We analyze those features of non-Abelian color gauge theories which lead to confinement. A consistent picture of hadrons as bound states of quarks and gluons emerges when the vacuum is gauge-invariant. The introduction of a transverse lattice approximation leads to a description of the theory in terms of basic hadronic degrees of freedom and a tractable method for calculation of properties of hadrons.
