    Our proposal for a symposium during the next EAS meeting in Leiden (June/July 2021) has been accepted! "The many faces of black hole accretion" symposium will be held online on July 1-2. The idea of the symposium is to discuss the wealth of multi-wavelength data that has been collected over the past few years, and the prospects to advance our knowledge of AGN physics in the near future. We plan to discuss both observations and recent theoretical results during the meeting, with the goal of gathering the European AGN community, a year before JWST will begin to revolutionise our view of galaxy evolution, to discuss the state of our knowledge in nearby SMBHs, and to forge synergies among forthcoming facilities and JWST.
