Active galactic nuclei (AGN) are accreting supermassive black holes co-evolving with their host galaxies through a complex interplay of feeding and feedback. In this chapter, we first discuss AGN fuelling in galaxies, both in interacting and isolated systems, focusing on the role that instabilities have on the angular momentum budget of the gas. We then review observations and models of feedback through AGN-driven winds from nuclear, sub-pc scales out to galactic and circumgalactic medium scales. We continue with an overview of surveys and statistical properties of the AGN population, before concluding with a discussion on the prospects for the future facilities, focusing in particular on Athena.
