Abstract: A characterization of descent morphism in the category of Priestley spaces, as well as necessary and su cient conditions for such morphisms to be e ective are given. For that we embed this category in suitable categories of preordered topological spaces were descent and e ective morphisms are described using the monadic description of descent.
