(Modern Shorkot) Rig Veda

Baudhayana Srauta
Sutra mentions, their king, Usinara ,

Shorkot (शोरकोट) , ancient name
Sibipura, town is located in the
Jhang district of Punjab, Pakistan.
[Jhang (Punjabi/Urdu: جھنگ,Hindi:
झंग) is the principle city of Jhang
District in the Punjab province of
Pakistan. It is situated on the
Chenab river at latitude 31.15° N
and longitude 72.22°E[1].
As per Diodorus [1], Arrian [2] and Strabo [3], the area surrounding Sibipura was occupied by a people called Sibi, during the time of
Alexander's invasion of Punjab.

Professor Eggermont [4] said, "J. Ph. Vogel showed that the mound of Shorkot (Jhang district, between Chenab, Indus, and Ravi rivers)
represents the site of Sibipura, the town (pura) of the Sibis, which is mentioned in a Shorkot inscription". Even today Sibi or Sibia is a well
known Jat clan in Punjab. Furthermore, Professor Eggermont [5] said, "However, I cannot possibly pass over in silence that in the very
Vessantara Jataka the town over which Sanjaya, king of Sibi, ruled is called Jettuttara and not Aritta-pura. It is probably more likely the word
Jetuttara is Jetupura or Jatupura which means the place where Jats live. The word "pura" in Sanskrit means "place".

The Buddhist Sibi Jataka (No. 499) contains their history and legends, and Vesantara Jataka, is named after a son of Sibia King of Jattaraur
(Chittor). Their capital in Punjab was Sibipura (Modern Shorkot) [14] Rig Veda mentions the Sibi people and Baudhayana Srauta Sutra
mentions, their king, Usinara , whom Indra saved from foreign aggression. They are the Sibai of Arrian and Siboi, of Deodorus. [15] [16]

Dr Pema Ram writes that after the invasion of Alexander in 326 BC, the Jats of Sindh and Punjab migrated to Rajasthan. They built tanks,
wells and Bawadis near their habitations. The tribes migrated were: Shivis, Yaudheyas, Malavas, Madras etc. The Shivi tribe which came
from Ravi and Beas Rivers founded towns like Sheo, Sojat, Siwana, Shergarh, Shivganj etc. This area was adjoining to Sindh and mainly
inhabited by Jats. The descendants of Shivi in Rajasthan are: Seu, Shivran, Shivral, Sihot, Sinwar, Chhaba etc.

Baudhāyana, was the author of the Baudhayana sūtras, which cover dharma, daily ritual, mathematics, etc. He belongs to the Yajurveda
school, and is older than the other sūtra author Āpastambha.
