Given a braided tensor V-category C with conjugate (dual) objects and irreducible unit together with a full symmetric subcategory S we define a crossed product C < S. This construction yields a tensor V -category with conjugates and an irreducible unit. (A V -category is a category enriched over Vec
classified the tensor-closed thick subcategories of finite-dimensional representations of finite groups over algebraically closed fields. In this paper, we remove the algebraically closed hypothesis by applying some Galois theory. Our methods apply more generally to finite-dimensional cocommutative
