Resolved stellar populations in the Local Group
Eva K. Grebel

The Local Group is the only place where we can study resolved stellar populations in a variety of different galaxy types down to the faintest individual stellar luminosities, lowest masses, and oldest ages. Moreover, many of the more luminous stars in nearby galaxies can be analyzed spectroscopically in order to measure their metallicities, element abundance ratios, and kinematics. As a result, we are obtaining information about their star formation and enrichment histories in unprecendented detail, revealing the dominant episodes of star formation, the importance of feedback and outflows, and of possible interactions. I will attempt to review our current knowledge of the Local Group derived from these detailed studies of their stellar populations.
