A first look at blazars with BeppoSAX
  I describe a general framework that could allow to understand the broad band spectra of blazars and lead to a unified picture of the emission from relativistic jets, in BL Lac objects as well as in flat spectrum, radio loud Quasars. The scheme serves as a useful basis to introduce and discuss some of the most in teresting results so far obtained on Blazars with BeppoSAX.
