  We propose the model of first quasars formation around the cluster of
rimordial black holes (PBHs). It is supposed, that mass fraction of the
universe ~10^-3 is composed of the compact clusters of PBHs, produced during
the phase transitions in the early universe. The clusters of PBHs become the
centers of dark matter condensation. As a result, the galaxies with massive
central black holes are formed. In the process of galaxies formation the
central black holes are growing due to accretion. This accretion is acompaned
by the early quasar activity.
