We present a Bayesian full-spectral-fitting analysis of 75 massive (M_>10^10.3^M{sun}) UVJ-selected galaxies at redshifts of 1.0<z10^11^M{sun}. We show that this is consistent with other spectroscopic studies from 0<z<2. This relationship places strong constraints on the AGN-feedback models used in cosmological simulations. We demonstrate that, although the relationships predicted by SIMBA and ILLUSTRISTNG agree well with observations at z=0.1, they are too shallow at z=1, predicting an evolution of =<0.5Gyr per decade in mass. Secondly, we consider the connections between green-valley, post-starburst, and quiescent galaxies, using our inferred SFH shapes and the distributions of galaxy physical properties on the UVJ diagram. The majority of our lowest-mass galaxies (M~10^10.5^M{sun}_) are consistent with formation in recent (z<2), intense starburst events, with time-scales of =<500Myr. A second class of objects experience extended star-formation epochs before rapidly quenching, passing through both green-valley and post-starburst phases. The most massive galaxies in our sample are extreme systems: already old by z=1, they formed at z~5 and quenched by z=3. However, we find evidence for their continued evolution through both AGN and rejuvenated star-formation activity.
