In this dissertation, we will focus on two of the most natural classes ofsubmanifolds that one can study in Riemannian manifolds. These are homogeneous hypersurfaces and totallygeodesic submanifolds.Regarding the first ones, we will conclude the classification of homogeneous hypersurfaces in symmetric spaces ofrank one, by finishing the classification in quaternionic hyperbolic spaces. As for totally geodesic submanifolds, wewill derive different classifications. In particular, we will classify totally geodesic submanifolds in the followingspaces: in products of symmetric spaces of rank one, in exceptional symmetric spaces, and in Hopf-Bergerspheres.
