In this paper, we prove there are at least two closed geodesics on any compact bumpy Finsler n-manifold with finite fundamental group and n≥ 2. Thus generically there are at least two closed geodesics on compact Finsler manifolds with finite fundamental group. Furthermore, there are at least two closed geodesics on any compact Finsler 2-manifold, and this lower bound is achieved by the Katok 2-sphere (S2, F) and 2-real projective space (S2/\Z2, F), cf. \citeKat.
