In the era of deep, large-area far-infrared (FIR) surveys from the Herschel Space Telescope, the bulk of the star-formation in distant galaxies, once hidden by dust, is now being revealed. The FIR provides probably the cleanest view of SF in the host galaxies of Active Galactic Nuclei (AGNs) over cosmic time. We report results from studies of the relationships between SF, AGN activity and AGN obscuration out to z=2.5, which employ some of the deepest Herschel and X-ray datasets currently available, while spanning orders of magnitude in the dynamic range of AGN properties. We highlight the role of gaseous supply in modulating both SF and AGN activity without necessarily implying a direct causal connection between these phenomenon. The role of starburst- or major merger-fueled AGN activity at low and high redshifts is discussed in the context of our results.
