SELF-DUAL N=1 SUSY GAUGE-THEORIES

We present a large set of new self-dual N = 1 SUSY gauge theories. Exa mples include SU(N) theories with tensors and SO(N) theories with spin ors. Using these dualities as starting points, new nontrivial duals ca n be derived by breaking the gauge group through the Higgs mechanism o r by integrating out matter. General lessons that can be learned from these duals are that ''accidental'' infrared symmetries play an import ant role in duality, many theories have more than one ''dual,'' and th ere seems to be no simple organizing pattern which relates duals of th eories with different number of flavors.
