The author studies the deformation of a flag variety and investigates the structure of a smooth closed subvariety in a projective space which is swept out by large dimensional linear spaces. Then a sufficient condition is given for the subvariety to be isomorphic to one of a projective bundle, a hyperquadric and a Grassman variety.
