A brief review of the globally supersymmetric grand unified theories is given. The new proposal of locally supersymmetric grand unification (supergravity GUTS) is discussed. Here the topics include, construction of the Lagrangian which couples the supergravity multiplet with an arbitrary number of chiral multiplets and a gauge vector multiplet, super‐Higgs phenomena and spontaneous breaking of supersymmetry and at a common weak interaction mass scale and phenomenological implications of supergravity GUTS. Questions relating to the ground state of the theory are also discussed.
