  Developments in understanding of Baryogenesis are reviewed. We start with
early motivations and the proposals in the context of GUTs. Next, the
importance of the sphaleron solution and its implications are discussed.
Studies of the Standard Model reveal that the latter has a Higgs structure
incompatible with existence of observed \B asymmetry. We then discuss a generic
scenario for electroweak baryogenesis relying on bubble wall dynamics. We also
summarise the status of the MSSM, and alternative scenarios utilising
topological defects as the source of non-equilibrium behaviour and
leptogenesis.
