  Supersymmetry (SUSY) is a complete and renormalisable candidate for an
extension of the Standard Model. At an energy scale not too far above the
electroweak scale it would solve the hierarchy problem of the SM Higgs boson,
dynamically explain electroweak symmetry breaking, and provide a dark-matter
candidate. Since it doubles the Standard Model degrees of freedom, SUSY
predicts a large number of additional particles, whose properties and effects
on precision measurements can be explicitly predicted in a given SUSY model. In
this review the motivation for SUSY is outlined, the various searches
strategies for SUSY particles at the LHC are described, and the status of SUSY
in global analyses after the LHC Run 1 is summarized.
