In the presence of magnetic monopoles, the baryon-number-violating effecs of grand unified gauge theories are not suppressed by inverse powers of the unification mass. As a result, monopoles catalyse proton decay at rates typical of the strong interactions. This phenomenon is caused by boundary conditions which must be imposed on fermion fields at the monopole core. They mix quarks and leptons and cause the monopole to have indefinite baryon number. We present a simplified account of these phenomena as well as their implications for proton decay and monopole search experiments.
