Does creation of galaxy depend on black holes? I've read many times that every galaxy contains a black hole at the center. So is the creation of a galaxy linked to black holes?
Most of the galaxies are believed to host a super massive black hole. The black hole in return has a dramatic impact on the evolution of the galaxy, an effect usually called "AGN feedback". Quoting W. Ishibashi, A. C. Fabian:


  Active Galactic Nuclei (AGN), regions of extremely high luminosity at the centers of some galaxies, are thought to radiate due to accretion onto a supermassive black hole.  This emitted radiation, or feedback, sends energy into its environment and influences the evolution of the host galaxy.  The details of this feedback are not well understood.  We do, however, observe several relationships between properties of the host galaxy and the central black hole — the most prominent of which is the M-sigma relation.  This empirical correlation states that the black hole mass (M) scales as the fourth power of the velocity dispersion (sigma) of stars in the galactic bulge.  Clearly, there is some connection between the evolution of the black hole and that of its host galaxy.


The topic of understanding how the supermassive black hole form in the first place, evolve and interact with their galaxy is still in debate among the scientific community, so it is impossible to fully answer your question yet.
