The Lambda CDM cosmology has been very successful in describing structure formation across the history of the Universe from the time of the CMB to the present day. However there remains a large gap in our history of galaxy formation, encompassing times between 380 thousand and 1 billion years after the Big Bang where observations remain sparse. This important epoch includes the formation of the first galaxies and the reionisation of hydrogen throughout the cosmos. In this talk I review some of what we know of this period, the new observations that will fill in pieces of the puzzle, and describe the Dark-ages Reionization And Galaxy-formation Observables from Numerical Simulations (DRAGONS) project which combines N-body and hydrodynamic simulations with semi-analytic and semi-numerical methods to produce a spatially dependent reionization model that is self-consistently coupled to the evolution of a realistic galaxy population.
