We investigate the stellar kinematics and stellar populations of 58radio-loud galaxies of intermediate luminosities (L$_{3 GHz}$ $>$ 10$^{23}$ WHz$^{-1}$ ) at 0.6 < z < 1. This sample is constructed by cross-matchinggalaxies from the deep VLT/VIMOS LEGA-C spectroscopic survey with the VLA 3 GHzdataset. The LEGA-C continuum spectra reveal for the first time stellarvelocity dispersions and age indicators of z $\sim$ 1 radio galaxies. We findthat $z\sim 1$ radio-loud AGN occur exclusively in predominantly old galaxieswith high velocity dispersions: $\sigma_*>$ 175 km s$^{-1}$, corresponding toblack hole masses in excess of $10^8$ M$_{\odot}$. Furthermore, we confirm thatat a fixed stellar mass the fraction of radio-loud AGN at z $\sim$ 1 is 5 - 10times higher than in the local universe, suggesting that quiescent, massivegalaxies at z $\sim$ 1 switch on as radio AGN on average once every Gyr. Ourresults strengthen the existing evidence for a link between high black-holemasses, radio loudness and quiescence at z $\sim$ 1.
