  The role of B decays in the study of CP violation is reviewed. We treat the
interactions and spectroscopy of the $b$ quark and then introduce CP violation
in $B$ meson decays, including time-dependences, decays to CP eigenstates and
non-eigenstates, and flavor tagging. Additional topics include studies of
strange $B$'s, decays to pairs of light pseudoscalar mesons, and the roles of
gluonic and electroweak penguin diagrams, and final-state interactions.
