In this chapter we formulate the first of several reduction by stages theorems in the regular, that is, free actions, case. We state a sufficient condition, called the stages hypothesis under which the two step reduced space is symplectically diffeomorphic to the space obtained by reducing all at once by the original group. In Chapters 11 and 12 we will come up with alternative conditions for reduction by stages based on the use of distribution theory.
