It is first reviewed how the concepts of a quantum field theories (QFT) and of local gauge invariance naturally arise, before they are applied to the electroweak model of leptons. This model is then extended to include quarks and the strong interaction, family replication and quark mixing, CP violation, as well as neutrino mass and mixing. Experimental tests, the determination of fundamental parameters, and constraints on and limitations of the minimal model and ideas that go beyond it are also covered.
