The host galaxies of radio-loud AGN can be characterized extremely well with HST data. We propose to extend our survey of low-power radio-loud AGN to much higher power, over a matching redshift range {0.1<=sssim z<=sssim 1.5}. Our study has two primary goals: beginitemize em{1} To assess the possible correlation of AGN nuclear luminosity with host galaxy magnitude, which might be expected from the black hole mass - bulge mass correlation in local galaxies. This has profound implications for the origin and evolution of galaxies and black holes. em{2} To observe directly evolution of the host galaxies of radio-loud AGN, without the usual confusion caused by the {unphysical} L-z correlation inherent in flux- limited samples. enditemize The proposed archival project concerns 69 quasars and radio galaxies from the well-defined 2 Jy sample. Building on our strong record of HST results on low-power AGN, this work will lead to a uniformly analyzed sample of nearly 200 radio-loud AGN, spanning a broad range in nuclear power at each redshift. Host galaxies will be detected and well characterized for at least half the sample, with careful attention to error analysis, using our already- developed analysis software.
