After Raavan was killed, Vibheeshan was crowned as king of Lankaa Puree. Seetaa was brought to Raam. After Her Agni Pareekshaa (Fire test) She was accepted by Raam and all took off to Ayodhyaa in Pushpak Vimaan.

My Note
The incident of Agni Pareekshaa is a controversial issue, because according to Maanas, Seetaa was safely kept with Agni Dev and a Maayaa (fake) Seetaa was kept for Raavan to take. Then it was simply necessary for Raam to get His real Seetaa back from Agni Dev. That is why this drama was created.

But in Raamaayan, it is not mentioned anywhere that Raam kept His Seetaa with Agni Dev, so this entering the fire incident looks like real one to test purity of Seetaa in front of the world.

They halted at Bharadwaaj Muni's place and Raam sent Hanumaan to Ayodhyaa to inform Bharat about His coming. Once more Ayodhyaa echoed with hustle and bustle of happiness of Raam's coming. The whole city was cleaned, decorated and illuminated. All mothers and Bharat and Shatrughn welcomed Raam, Lakshman and Seetaa back to Ayodhyaa. Bharat handed over Raam's crown back to Raam.

[Maanas ends Raam kathaa here.]

It is said that Raam ruled Ayodhyaa for 10,000 years. All brothers had two sons each. Raam had Lav and Kush who were born in Vaalmeeki Jee's Aashram, because Raam exiled Seetaa on doubts of a washerman's (who washes clothes) comments. After 12 years when Raam did Ashwamedh Yagya, Lav and Kush caught His horse and didn't release it at any cost. Raam's army came, Lakshman, Bharat and Shatrughn came to take that horse but all were defeated. Then Raam Himself had to come to get His horse. 

Then Vaalmeeki Jee held them back to fight with Him saying that He was their father. Later Raam expressed His desire to have Her back but after giving the proof of Her purity again. Vaalmeeki Jee brought Seetaa in the royal court of Raam. Seetaa said - "If I have always been loyal to my husband then my mother Earth should give me shelter in her laps." Everybody got stunned hearing this kind of proof. But it has already been said. Mother Earth ripped apart and took Her in her lap and Seetaa went to her Lok.

Raam got very sad seeing this. His life became hell thinking about Seetaa all the time. One day Kaal came and delivered the message of Brahmaa Jee that His time on Prithvi was now over, so He should come back to His Lok. Raam, Lakshman, Bharat and Shatrughn settled their sons in their kingdoms and all took Jal Samaadhi in Sarayoo River. Many other people who came with Him (took birth only for His work) also went with Him. Whatever creation was created for Raam, everybody went with Raam's going to Swarg.
