Raja Dasharatha of Ayodhya had three wives. The names of his wives were Kaushalya, Kaikeyi and Sumitra.
Ram Chandra was the son of Kausalya. Bharat was the son of Kaikeyi. Lakshman and Shatrughan were the sons of Sumitra.
Ram Chandra was married to Sita, the daughter of Raja Janak of Videha. Raja Dasharatha declared Ram Chandra to be his heir-apparent as he was the eldest as well as the ablest of all his sons.
This infuriated his step mother (Kaikeyi) wanted Bharat to be the successor of her husband. And as such, she manipulated to get Ram Chandra exiled from the country for a period of 14 years.
As a loyal and faithful son, Ram Chandra obeyed the order of his father and went over to jungles along with his wife, Sita and brother, Lakshman. As the chance had it, Ravana, the ruler of the Lanka, took away Sita to his country. Rama, with the help of Lords Hanuman and Sugriva raged a war against Ravana in which the later was killed and Sita was got back.
