Last year or so has seen a revival of interest in the dynamics of supersymmetric gauge theories. In this review we give  (i) an introduction and a review of the earlier results in the field;  (ii) discuss a more recent work of my own and of my collaborators on non-Abelian monopoles, vortices and confinement; and in the last lecture, we discuss  (iii) the latest development in the dynamics of  N=1 gauge theories.
