In the early universe all matter that later forms gravitationally bound structures acquires an initial angular momentum through interaction with the gravitational tidal field. This initial spin is preserved during structure formation and determines the rotation of dark matter haloes at all redshifts. However, galaxies at low redshift are observed to have substantially higher spin than the surrounding dark matter. This originates in the impact of supernova and AGN feedback on the gas content of the galaxy and its decisive role in shaping galaxy morphology. In this talk I will discuss the main feedback mechanisms at play and explain how they regulate the angular momentum content of galaxies. Using insight from the hydrodynamical cosmological simulations Illustris and IllustrisTNG I will show evidence for the spin of galaxies to be independent of the detailed feedback prescription.
