I would guess it all began with a larger-than-normal black hole, that, over time, swallowed up other additional black holes (can they do that?) or massive stars that also collapsed and kept adding to the central galactic black hole...
Which brings me back, because I am a bit fuzzy on this, to: if two black holes meet with one another, do they combine and form a larger black hole together? It is a rip in the "fabric" of space-time, so what happens when those "rips" overlap or come in contact?

What collapsed and created the Supermassive black holes in center of galaxies? Where Galaxies once really, really, really massive stars? Something had to collapse and make them right?
Here's the wiki early history. Not long after the big bang the universe matter was nearly homogeneous, key word being nearly. There were slight variations and the slightly denser regions over time collapsed to form various structures, starting with quasars which were early types of galaxies with black holes that consumed huge amounts of matter and gave off huge amounts of radiation. The formation of galaxies evolved over time as they "collided" and formed more spiral structures like that of our Milky Way, which were absent in the earliest universe.

Structure formation in the big bang model proceeds hierarchically, with smaller structures forming before larger ones. The first structures to form are quasars, which are thought to be bright, early active galaxies, and population III stars. Before this epoch, the evolution of the universe could be understood through linear cosmological perturbation theory: that is, all structures could be understood as small deviations from a perfect homogeneous universe. This is computationally relatively easy to study. At this point non-linear structures begin to form, and the computational problem becomes much more difficult, involving, for example, N-body simulations with billions of particles.
150 million to 1 billion years after the Big Bang
The first stars and quasars form from gravitational collapse. The intense radiation they emit reionizes the surrounding universe. From this point on, most of the universe is composed of plasma.
Formation of stars
The first stars, most likely Population III stars, form and start the process of turning the light elements that were formed in the Big Bang (hydrogen, helium and lithium) into heavier elements. However, as yet there have been no observed Population III stars, and understanding of them is currently based on computational models of their formation and evolution. Fortunately observations of the Cosmic Microwave Background radiation can be used to date when star formation began in earnest. Analysis of such observations made by the European Space Agency's Planck telescope, as reported by BBC News in early February, 2015, concludes that the first generation of stars lit up 560 million years after the Big Bang.
I will extend the OP question further and ask the board, how and why BH evaporate? What happens to all the mass that fell into it?
