We propose a many-body generalization of the Z2 topological invariant for thequantum spin Hall insulator, which does not rely on single-particle bandstructures. The invariant is derived as a topological obstruction thatdistinguishes topologically distinct many-body ground states on a torus. It isalso expressed as a Wilson-loop of the SU(2) Berry gauge field, which isquantized due to the time-reversal symmetry.
