Abstract
In this paper we develop a Morita theory for associative rings without identity using the categories CMod-R of modules M such that M ≃ Hom(R,M) and DMod-R of modules M such that M ⊗ R ≃ M. This extends the main results of Morita theory to a wide class of rings, that properly includes the idempotent rings.
