Accretion onto supermassive black holes (SMBHs) located in the centre of active galaxies is one of the most significant energy sources in the Universe. Since the X-ray emission of Active Galactic Nuclei (AGN) is the result of the complex interaction between the primary radiation field and the ambient material via absorption, scattering and reflection, X-ray observations are fundamental to investigate the physical processes taking place in the innermost regions of the accretion disc, as well as the structure of the circumnuclear environment. I will present some recent results that shed new light on both the workings of the central engine and the possible link between the growth of SMBHs and the evolution of their host galaxies over cosmic time.
