Rajasuya

[1] According to the Puranas, it refers to a great sacrifice performed by a Chakravarti – universal monarch, in which the tributary princes may also take part, at the time of his coronation, as a mark of his undisputed sovereignty.

[3] It is described in the Taittiriya corpus, including Apastamba Śrauta Sutra 18.8–25.22.

[1] It involves soma pressing, a chariot drive, the king shooting arrows from his bow, and a symbolic "cattle raid":[1] The newly anointed king seizes cattle belonging to his relative, and then gives part of his property to that relative.

[1] There is a revealing of the tale of Shunahshepa, a boy who was nearly sacrificed to Varuna on behalf of the sonless king Harishchandra, which hints at a rejected archaic practice of human sacrifice.

[5] Historically, the rajasuya was performed by the Indo-Aryan kings, which led to the expansion of their kingdoms during the Iron Age.
