Abstract: We have performed numerical simulations of interacting galaxies in which the evolution of the entire star cluster population is computed, combining parameterised cluster models with an N-body/SPH code. The effect of the (changing) tidal field on cluster evolution is accounted for. We find that star clusters are destroyed in galaxy mergers, despite a strong increase of the star formation rate. The destruction rate decreases with increasing mass, implying that above a certain initial cluster mass the net result is an increase of the number of star clusters, indicating the formation of a cluster population that likely precedes present-day globular cluster systems.
