The multiwavelenght counterparts to eROSITA/DR1 and the AGN content 

Galaxy evolution can only be understood if its AGN phases are accounted for. For that, a complete and pure census of AGN is needed. Hunting for AGN in X-ray is the most obvious way to go, given the low emission from galaxies at this frequency. In the last 20 years, XMM and Chandra have provided us mostly with pencil-beam surveys, thus sampling the faint and high-redshift regime. Finally, with eROSITA, we can also sample the rare (local and z>5.5) and faint Universe. In my talk, I will first present how we reliably identified the counterparts to the eROSITA sources. I will then review the multi-wavelength properties (including redshifts) of the first eROSITA AGN sample and compare them with AGN selected from other surveys.
