I found this from Internet. This guy quote chachnama and claims for big political and social power of jats in ancient Sindh before chach. Brahmins were much lower in the status in jats eyes. It were muslim sources and chach which degraded jats in their writings, and chach put derogatory restrictions on jats.
Not only sahasi but Akham Lohana ruler of Brahmanabad and Matta ruler of sivistan(Now Eastern Balochistan) were also Jats .
Akham was leader of lohana Samma and Sohotta jatt tribes and jats because of their birth decent thought them superior to any body else and particularly brahmans that has been admitted by Chach himself to wrote a letter in that regard...Quote Chachnama.....
Chach sends a letter to Akham Lohána.
Ráí Chach sent a letter to Akham Lohána, saying, "You from your
power, and pomp, and family descent, consider yourself the ruler of the time. Although this kingdom and sovereignty, wealth, riches,
dignity, and power have not descended to me by inheritance, yet these distinguished favours and this exalted position have been given to me by God. It was not by my army that I gained them;"
Here it is shown as far as family decent was concerned Akham Jatt was
treated much superior than Brahman chach."
I will give proofs regarding jatt decent of Akham lohana.
However I will try to clear certain other controversial points.
I feel Sahasi was a name of son of sahiras not a title .
Sahasi rai rulers had shahi clan ,I don't know about morya connection.
Though kabul kings were jats termed brahmans but Chach was certainly a brahman not any othercast as he along with his father used to live in a temple where his father was a priest and lead a poor life so no confusion regarding that .
