Abstract: The Milky Way was thought to be dynamically young with a fairly smooth potential dominated by a nearly spherical dark matter halo that has evolved little in the last several billion years. This talk outlines our evolving view of our home galaxy, inspired by the ever-growing catalogues that have mapped it – from the Sloan Digital Sky Survey to the Gaia mission.
