For historical reasons the local symmetry group is known as a gauge group (strictly of the so-called second kind - the corresponding global symmetry is a gauge symmetry of the first kind) and the hope is widely shared that all interactions, including electromagnetic, strong, weak, and even gravitational, can be derived by imposing the appropriate local gauge symmetry.
