The interpretation of the difference observed between the radial distribution
of globular clusters and that of halo-bulge stars in elliptical galaxies is
discussed in terms of evolution of their globular cluster systems. I present a
short summary of the evidence that dynamical evolution of globular cluster
systems is not only able to explain the flattening of their distribution toward
the galactic center, but also it may have played an important role on the
primordial activity of the parent galaxy.Comment: Presented at the MPIA Workshop on Modes of Star Formation and the
