The bimodal age-metallicity relation of globular clusters (GCs) suggests that up to two thirds of the Galactic halo GCs may have been accreted as part of disrupted dwarf galaxies. The properties of the GCs can tell us about the small host galaxies in which they formed based on empirical mass-metallicity relations. GCs themselves may get disrupted in the Galactic potential, contributing their stars to the halo field population. We will run computer models of long-term GC evolution, starting from a set of generic initial conditions up to the current time, which will provide us in this funding period with quantitative information about the GC-halo interaction. Large, realistic direct N-body models of GCs include galactic tidal fields, single and binary stellar evolution, cluster rotation. This will be complemented by detailed follow-up studies of our spectroscopically identified secondgeneration, former GC member candidates among field stars in the Galactic halo. Chemical fingerprinting combined with phase-space information from Gaia DR2 and DR3 will help us to associate these present-day field stars with their birth places.
