Tracing the Local Group evolution with resolved stellar populations

Local Group dwarf galaxies provide valuable information about the early Universe through the detailed study of their resolved stellar populations. In this talk I will present our latest results on few galaxies (Draco, CVnI, Sextans), focusing on the synergies between different techniques applied to resolved stellar population studies. In particular, different approaches such as the star formation history derivation from the deep colour-magnitude diagrams combined with the properties of variable stars can provide interesting insight on the host galaxy evolution, chemical evolution, and accretion history.
