The stellar populations in M31 and its companions are reviewed from both historical and more modern contexts. Recent data for nearby resolved galaxies suggest that a revision of Baade's original population concept, particularly as applied to elliptical galaxies, is required. In addition, these new data highlight the difficulties in interpreting the data for, and the lack of direct information on, the more distant giant elliptical galaxies being used for cosmological studies.
