Determining the ages of stars in our Milky Way, the nearby Andromeda galaxy and their satellite dwarf galaxies, gives us a window into how efficiently these objects assembled their baryonic mass.  These star formation histories also indirectly encode information about the dynamical state of the gas during a galaxy’s infancy.  Such gas properties provide us with a unique way to study how galactic disks initially settle, and subsequently how dense star clusters (Globular Clusters) form in the chaotic high-redshift universe.   In this talk I will show examples of how our friendly neighbouring galaxies can constrain models for Globular Cluster formation and survival, and help interpret complementary, direct observations of high-redshift galaxy disk kinematics.
