The nine-day Navaratri festival culminates with the celebration of Dussehra or Vijayadashami (victory on tenth day). Dussehra is celebrated as the victory of Lord Rama over demon king Ravana of Lanka. Dussehra also commemorates the triumph of warrior Goddess Durga over the buffalo-headed demon called Mahishasura, giving the goddess her name Mahishasura-Mardini (the slayer of Mahishasura).
