There is growing evidence that the hard X-ray background (XRB) can be explained by a large population of obscured AGN. I review some of the results of recent deep X-ray surveys, and in particular I discuss the nature of the X-ray luminous emission-line galaxies which have emerged at the faintest X-ray fluxes. If obscured AGN do explain the XRB, a direct implication is that the majority of the energy produced by accretion in the universe is absorbed and not emitted directly. Deep submillimetre surveys with SCUBA have recently attracted a lot of attention, with the potential to allow us an unobscured view dust-enshrouded starformation at high redshift. It has generally been assumed that these sources are purely high redshift starforming galaxies, but if models for the XRB are correct then a significant fraction (~ 20%) could contain a luminous AGN.
