Sita gets introduced to Rama at a ceremony called ‘Swayamvara’, organized by her father Janaka, the king of Mithila to identify a suitable bridegroom for her lovely daughter. Princes from various kingdoms are invited and challenge to string a giant bow. Only the mighty Rama could lift the bow, string it and even break it into two halves. This leads Sita to garland Rama as her husband.
Dasharatha, the king of Ayodhya, had three wives and four sons. Rama was the eldest and his mother was Kaushalya. Bharata was the son of his second and favorite wife, Kaikeyi. The other two were twins, Lakshmana and Shatrughna from his third wife Sumitra.

While Rama is all set for coronation, his step-mother, Dasharatha’s second wife, Kaikeyi, wants her son, Bharata, to become king. Before the aged king could hand over his crown to his eldest son Rama, Dasaratha is destined to die. And instead of being crowned king of Ayodhya, Rama is sent into exile in the forest  (sri lanka)for fourteen years.
While Rama, his wife and brother are living a simple yet happy life in the forest, tragedy strikes! Henceforth, the plot revolves around the abduction of Sita by the demon king Ravana, the ten-headed ruler of Lanka, and Rama’s pursuit to rescue her, aided by Lakshmana and the mighty monkey-general Hanuman. Sita is held captive in the island as Ravana tries to persuade her to marry him. Rama assembles an army of allies comprising mainly of monkeys under the brave Hanuman. They attack Ravana’s army, and after a fierce battle, succeed in killing the demon king and freeing Sita, reuniting her.

and after 14 years rama and sita return back to ayodhya and were given a rousing welcome back by the citezins.
