  Keck spectropolarimetry, giving spectral coverage from Ly-$\alpha$ to beyond
CIII], and HST imaging of a sample of powerful radio galaxies with $z\sim2.5$\
has been obtained. These data are giving us a clear picture of the nature of
the `alignment effect' and are revealing new correlations between polarization
and emission line ratios which may be interpreted in the context of the stellar
evolutionary histories of these massive galaxies. In particular, we see the
2200\AA dust absorption feature in the radio galaxy continua and a large
variation in the NV/CIV line ratio amongst objects having a similar ionization
level. VLT infrared spectroscopy of this and similar samples will give us a
view of a period of galaxy history during which rapid chemical evolution was
taking place.
