Multiwavelength identification campaigns from medium deep and deep X-ray surveys with XMM and Chandra have opened a new perspective in the study of the high-redshift (z>3) AGN population.
However, samples sizes have been quite limited because large area surveys have been too shallow, and the deep survey areas are too small. For the first time, were able to provide sizable samples of AGN with luminosities above logLx=43.5. We present the properties of the largest sample (72 sources) of X-ray selected z>3 AGNs, from the Chandra COSMOS survey. This sample defines the space density and evolution of the z>3 X-ray selected AGN population. With 9 sources, we well sample the z>4 population, and the z>5 population is beginning to emerge with a 2 source sample plus a candidate at z=6.8. The results are compared with predictions from XRB synthesis models and semianalythic models of galaxy formation.
