We present initial follow-up results of the ELAIS Deep X-ray Survey
which is being undertaken with the Chandra and XMM-Newton Observatories.
235 X-ray sources are detected in our two 75 ks ACIS-I observations in
the well-studied ELAIS N1 and N2 areas. 90% of the X-ray sources are
identified optically to R=26 with a median magnitude of R=24. We show
that objects which are unresolved optically (i.e. quasars) follow a
correlation between their optical and X-ray fluxes, whereas galaxies do
not. We also find that the quasars with fainter optical counterparts
have harder X-ray spectra, consistent with absorption at both wavebands.
Initial spectroscopic follow-up has revealed a large fraction of
high-luminosity Type 2 quasars. The prospects for studying the evolution
of the host galaxies of X-ray selected Type 2 AGN are considered.
