  The aim of this AAS Topical Session was to update the community on the
current state of knowledge about the angular momentum evolution of young stars.
For newcomers to the subject, the session was intended to provide an
introduction and general overview and to highlight emerging issues. For
experienced workers in this field, the session provided an opportunity for
synthesizing recent developments in observations, theory, and modeling of
rotation of young stars and for identifying promising new research directions.
