  We discuss integrable many-body systems in one dimension of
Calogero-Moser-Sutherland type, both classical and quantum as well as
nonrelativistic and relativistic. In particular, we consider fundamental
properties such as integrability, the existence of explicit solutions as well
as action-angle and bispectral dualities that relate different such systems. We
also briefly discuss the early history of the subject and indicate connections
with other integrable systems.
