Tremendous progress has been made in our knowledge of the spin distribution within the proton. We present the original data and the suggestion that polarized gluons, via the U(1) axial anomaly, may be essential in resolving the proton spin puzzle. The recently measured limits on polarized gluons in the proton make it obvious that the resolution of the proton spin puzzle lies in the non-perturbative structure of the proton. We will show that a modern, relativistic and chirally symmetric description of the nucleon structure naturally explain the urrent proton spin data.
