  I discuss how spectroscopy of extragalactic globular clusters provides a
powerful probe of the formation history and mass distribution of galaxies. One
critical area is spectroscopy of objects which have been identified as
candidate young globular clusters through HST imaging of galaxy mergers. I
discuss how such data can constrain models of globular cluster and galaxy
formation. As an example, I present new spectra which confirm the presence of
young globular clusters in NGC 1275. A second way wide-field spectroscopy can
be used to probe the formation history and mass distribution of galaxies is
through spectroscopy of large numbers of globular clusters around elliptical
galaxies. Metallicities obtained from such data place strong constraints on
models of galaxy formation, and velocities determined from the same data
provide kinematical tracers of the mass distribution out to distances of $\sim
100$ kpc.
