We find the phases and flavour symmetry breaking pattern of each N=1 supersymmetric vacuum of SU(n), USp(2n) and SO(n) gauge theories, constructed from exactly solvable N=2 theories perturbing them with small adjoin and generic quark masses. Monopoles of the maximal Abelian gauge subgroup represent the low-energy degrees of freedom only in a restricted number of vacua. In more typical vacua the constituents of the monopole, dual quarks, describe the low-energy physics. Their condensation induces confinement and dynamical symmetry breaking simultaneously. In another class of vacua, however, the low-energy physics is described by non-trivial interacting superconformal theories. For larger numbers of flavour, there are also vacua in the free magnetic phase.
