    The hierarchical nature of galaxy formation in the standard model of cosmology (LCDM) predicts a diffuse stellar halo component around Milky Way-mass galaxies, formed from the accretion and disruption of dwarf galaxies. Using cosmological hydrodynamical simulations of Milky Way like halos, I will compare the properties of these destroyed dwarfs which built up the stellar halo with those of existing satellites. I will then connect these results with recent findings from the Gaia mission related to the major event in the formation history of the Milky Way.
