A review will be given on supersymmetry breaking and some aspects of non-linear supersymmetry. A new type of N=1 Fayet--Iliopoulos (FI) terms in supergravity will be discussed. These do not require gauged R-symmetry in contrast to the previous FI-supergravities. These new actions correspond to the description of anti-D3 branes in supergravity by super Born--Infeld terms.
