A unified theory of photopion reactions in two-nucleon systems (..gamma..d..-->..pn, ..pi../sup 0/d, and ..pi..NN) and NN bremsstrahlung (NN..-->..NN..gamma..) is presented. By exposing the two-body (BB, where B = N or ..delta..(1232)) and three-body (..pi..BB and ..gamma..BB) unitarity, we derive a set of coupled integral equations to determine the amplitudes for these reactions. These equations have the same kernel as the equations one gets for the BB-..pi..BB system. The two-body input amplitudes are the result of a coupled channel unitary theory for ..pi..N..--> pi..N and pion photoproduction on a single baryon, within the framework of a gauge and chirally invariant Lagrangian, which is obtained from the chiral bag model Lagrangian. The renormalization due to the ..pi..B interaction is incorporated in a consistent manner.
