	26	Prajval Shastri	Different Angles on AGN: Some Empirical Tests of the Unification Paradigm Much of current AGN research is worked into the operating framework of the 'Unification Paradigm', which is based on the notion that orientation plays a dominant role in the appearance of active galaxies. I will describe the results of a variety of empirical tests of unification, in both the radio-loud and radio-quiet regimes.
