In this talk, I will first review the motivations for "grand unification" of forces and the experimental hints in its support. Then I will describe recent progress in model building based on a class of supersymmetric grand unified theories. Small neutrino masses leading to neutrino flavor oscillations is a natural outcome of these theories.Expectations for neutrino oscillation parameters and for the quark masses and mixing angles will be outlined. A hallmark prediction of grand unified theories is the violation of baryon number and the ultimate instability of matter. Proton must decay with a lifetime accessible to experiments. Neutron may oscillate into anti-neutron with a lifetime reachable in proposed experiments. A possible link between neutron--anti-neutron oscillations and the cosmological baryon asymmetry will be discussed. Experiments at the Large Hadron Collider can shed light on various aspects of grand unification, which will be outlined.
