  These pedagogical lecture notes present a general introduction to most
aspects of the integer and fractional quantum Hall effects. This is followed by
an extensive discussion of quantum Hall ferromagnetism, both for spins in
single-layer systems and `pseudospins' in double-layer systems. The effective
field theories describing various broken symmetry states and `skyrmion' and
`meron' spin textures are derived and discussed in some detail. Pedagogical
presentations on Berry phases and lowest Landau level projection are included
in appendices.
