Galaxies less massive than the Small Magellanic Cloud (10^8 Msun) have become increasingly relevant to a broad range of astrophysics from cosmic reionization to deciphering the nature of dark matter. Yet, they are simply too faint to be directly detected at any appreciable redshift, compromising our ability to place them into a cosmological context. In this talk, I will describe how observations of resolved stellar populations in Local Group galaxies provide unique insight into the lowest-mass galaxies in the Universe, and comment on the role next-generation facilities can play in linking low-mass galaxies near and far.
