Despite the strong tidal field exerted by the supermassive black hole (SMBH) in the Galactic Centre, more than a hundred young massive stars are observed in the central parsec of the Galaxy. These include a thin disc of O-stars and Wolf-Rayet stars orbiting the SMBH on low-eccentricity orbits, as well as a smaller number of B stars on isotropic eccentric orbits. These stars, whose orbits provide the most accurate dynamical measurement of the mass of a SMBH , also pose important constraints on current models of star formation and dynamical evolution in galactic nuclei. I will review the main models for the origin of the young stars and discuss possible observable signatures that can be used to study the recent star formation history of the Galaxy.
