Over 200 quasars have now been discovered at z > 6, with nine at z > 7, just 690 Myr after the Big Bang. The leading contenders for the seeds of these supermassive black holes are direct-collapse black holes (DCBHs) due to the collapse of 10^4 - 10^5 solar-mass primordial stars at z ~ 20. It has long been thought that these supermassive stars required unusual, exotic environments to form that were difficult to pair up with the rare, massive halos required to ensure the growth of these seeds to 10^9 solar masses by z ~ 7. However, we have performed new, state of the art numerical simulations that the rare halos capable of hosting SMBHs by this redshift formed their own seeds without any need for unusually strong Lyman-Werner UV backgrounds, supersonic baryon streaming motions, or even atomic cooling. Besides overturning nearly 20 years of thought on the origin of the first quasars, our simulations show that z > 6 SMBHs were a natural consequence of structure formation in cold dark matter cosmologies. They also account for the demographics of these objects, about 1 Gpc^-3 at z ~ 6.
