  We show how an effective field theory of long distance QCD, describing a dual
superconductor, can be expressed as an effective string theory of
superconducting vortices. We use the semiclassical expansion of this effective
string theory about a classical rotating string solution in any spacetime
dimension D to obtain the semiclassical meson energy spectrum. We argue that
the experimental data on Regge trajectories along with numerical simulations of
the heavy quark potentials provide good evidence for an effective string
description of long distance QCD.
