We discuss constraints on the assembly history of supermassive black holes\nfrom the observed remnant black holes in nearby galaxies and from the emission\ncaused by accretion onto these black holes. We also summarize the results of a\nspecific model for the evolution of galaxies and their central black holes\nwhich traces their hierachical build-up in CDM-like cosmogonies. The model\nassumes (i) that black holes, ellipticals and starburts form during major\nmergers of galaxies (ii) that the gas fraction in galaxies decreases with\ndecreasing redshift (iii) that the optical bright phase of a QSO lasts for\nabout 107 years. The model succesfully reproduces the evolution of cold gas as\ntraced by damped damped Lyman alpha systems, the evolution of optically bright\nQSOs, the remnant black hole mass distribution and the host galaxy luminosities\nof QSOs.\n
