How did the formation of the first stars and galaxies end the cosmic dark ages, a few hundred million years

after the Big Bang? I will review our emerging theoretical framework of this fundamental cosmic transformation,

taking stock of what we know, just ahead of the JWST launch. How do the first supernovae enrich the pristine

intergalactic medium, and how does the energetic feedback from stars and black holes shape the assembly

process of the first galaxies? I will discuss strategies to probe our theoretical ideas, both with frontier observations

at high redshifts, and with surveys of local metal-poor stars ("stellar archaeology").
