Koenig's theorem describes a necessary and sufficient criterion for the existence of a recollement of derived categories of rings.This paper gives Koenig's theorem for the version of a recollement of module categories of rings.As two applications,we give a new proof of Morita's equivalent theorem and describe the close relation between a triangular matrix ring and a recollement of module categories of rings.
