A survey of the relationship between magnetism and superconductivity in high-temperature superconductors is presented. It is shown that strong electron correlations are responsible for magnetic behavior and for the specific electronic structure of the charge carriers. A survey of various proposals for a magnetic origin of high-temperature superconductivity is given, including the possibilities of unconventional pairing, new mechanisms, and new forms of the many-body theory. An important issue is whether superconductivity is an intrinsic property of mobile holes in an antiferromagnet. This possibility is compared and contrasted with more conventional approaches to the problem.
