We investigate the luminosity evolution of the host galaxies of radio-loud AGN through Hubble Space Telescope imaging of 72 BL Lac objects. This sample has enabled us to avoid the biases implicit in quasar studies. We find that the host galaxies of BL Lacs evolve strongly, consistent with that obser
