We consider D-branes in group manifolds, from the point of view of open strings and using the Born-Infeld action on the brane worldvolume. D-branes correspond to certain integral (twined) conjugacy classes. We explain the integrality condition on the conjugacy classes in both approaches. In the Born-Infeld description, the D-brane worldvolume is stabilized against shrinking by a subtle interplay of quantized U(1) fluxes and the non-triviality of the B-field.
