The dwarf spheroidal galaxies of the Local Group represent the smallest scales on which galaxies are able to form. As such, they are excellent probes of galaxy formation physics. They are also interesting laboratories for understanding dark matter, owing to their large mass-to-light ratios. In this talk, I will highlight how we can use these smallest of galaxies to both test the cosmological paradigm, and to better understand the processes governing galactic formation and evolution. I will also talk about the connection between Local Group dwarf spheroidals and the new class of ultra-diffuse galaxies, which have been found in cluster environments.
