Abstract One of the main objectives of the ROSAT mission turned out to be the study of active galactic nuclei. The soft energy range of the X-Ray Telescope combined with the good energy resolution of the PSPC detector allows an investigation of the spectral properties of sources in this energetically important energy band. The high sensitivity of the instrument in the All Sky Survey will yield more than 25000 previously unknown X-ray AGN for the statistical and morphological exploration of these objects. A short overview is given of the actual ongoing research which ranges from the detailed spectral study of some well known objects and correlations of samples of AGN with existing catalogues at other wavelengths to identification programmes for large numbers of suspected AGN candidates.
