Abstract: I will discuss the relevance of the spins of massive black holes as probes of the coevolution of these objects with their host galaxies, as well as for the dynamics of binary systems and accretion disks, and for gravitational-wave emission. I will also present a semi-analytical model for the cosmological evolution of the spins of the massive black-hole population, and show that comparison of this model to existing spin measurements from relativistic iron lines allows one to put constraints on competing accretion scenarios. I will also comment on the prospects to test this model using future gravitational-wave space-based detectors.
