Gaia space mission has published in September 2016 its first data release. In the years to come, exquisite astrometry, photometry and spectroscopy will be available for hundreds of millions of targets, opening a new era of discoveries in galactic archaeology. In this proceeding, I review some key aspects, such as kinematic and metallicity gradients in the Galaxy, that are linked to the internal and external mechanisms that influence Galaxy evolution and that have already started to be clarified with GDR1.
