    Summary
    Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in protoclusters at z>1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, which preferentially reside in rich environments. We compare the environments of powerful RLAGN at 1.31014 M⊙ cluster having experienced powerful radio-loud feedback of duration ∼60Myr during 1.3
