Ravana was king of Lanka. He had ten heads. He took away Sita, wife of Rama (an avatar of Vishnu). Rama attacked him. He and his army fought with Ravana, with the help of the monkey army of King Bali and his army. At last, Ravana was killed.
when rama returned to ayodhya (his native place) , someone told that a woman who lived with other men should not stay with her husband . so rama sent sita away to the forest. this tells us that rama did'nt give respect to his wife who had made many sacrifices for him
