A model for the origin of the cosmic X-ray background (hereafter XRB) is presented. The component of the background left after subtraction of the known classes of sources is explained by emission from a population of black hole sources at the redshift of z ∼ 4–5. The model is presented in more detail elsewhere (Zdziarski 1988). Here, we summarize its most important results.
