  The Dark Side of the Universe, which includes the cosmological inflation in
the early Universe, the current dark energy and dark matter, can be
theoretically described by supergravity, though it is non-trivial. We recall
the arguments pro and contra supersymmetry and supergravity, and define the
viable supergravity models describing the Dark Side of the Universe in
agreement with all current observations. Our approach to inflation is based on
the Starobinsky model, the dark energy is identified with the positive
cosmological constant (de Sitter vacuum), and the dark matter particle is given
by the lightest supersymmetric particle identified with the supermassive
gravitino. The key role is played by spontaneous supersymmetry breaking.
