  We extend the coupled-wire construction of quantum Hall phases, and search
for fractional topological insulating states in models of weakly coupled wires
at zero external magnetic field. Focussing on systems beyond double copies of
fractional quantum Hall states at opposite fields, we find that spin-spin
interactions can stabilize a large family of fractional topological phases with
broken time reversal invariance. The latter is manifest by spontaneous spin
polarization, by a finite Hall conductivity, or by both. This suggests the
possibility that fractional topological insulators may be unstable to
spontaneous symmetry breaking.
