  Young star clusters in interacting galaxies are often found in groups or
clusters of star clusters containing up to 100 single clusters. In our project
we study the future fate of these clusters of star clusters. We find that the
star clusters merge on time scales of a few dynamical crossing times of the
super-cluster. The resulting merger object has similarities with observed dwarf
ellipticals (dE). Furthermore, if destructive processes like tidal heating,
dynamical friction or interaction with disc or bulge of the parent galaxy are
taken into account our merger objects may evolve into objects resembling dwarf
spheroidal galaxies (dSph), without the need of a high dark matter content.
