  We summarise recent results on the properties of gluons, quarks and light
mesons from the Green's functions approach to QCD. We discuss a
self-consistent, infrared power law solution for the Schwinger-Dyson equations
of the 1PI-Greens functions of Yang-Mills theory. The corresponding running
coupling has a universal fixed point at zero momentum. Based on these
analytical results a truncation scheme for the coupled system of
Schwinger-Dyson equations for the propagators of QCD and the Bethe-Salpeter
equation for light mesons has been formulated. We compare numerical results for
charge eigenstate vector and pseudoscalar meson observables with corresponding
lattice data. The effects of unquenching the system are found to be small but
not negligible.
