Maharaj Dashrath had everything but had no children.

To have children he decided that he will perform Aswamedha Yajna.

He ordered his minister Sumantra to invite all the sages to Ayodhya.

Suyagaya, Vamdev, Jabali, Kashyap, Vasistha and many other sages with similar capacity visited Ayodhya.

It was decided that Yajna will be performed at the right bank of river Saryu.

The Yajna horse was released along with 400 soldiers.

The sacrifice started when horse returned after wandering in all directions after one year.

Rishyashringa muni was the head priest of Aswamedha sacrifice.

People from all caste including Shudra attended the sacrifice.
