Let K be a field and let X be an abelian variety over K. The group Aut X of K-automorphisms of X acts in a natural way on the set of abelian subvarieties of X that are defined over K. In this paper it is proved that the number of orbits is finite. The proof makes use of a finiteness result about semisimple algebras
