The search for any indigenous Brahmi based scripts often starts & terminates at Hat-Wanaki. This despite that fact that Sindhu-Saraswati civilization of Sindh had the very nucleus of not only Indus valley civilization but of Vedic civilization as well. Arabic Writer Al- Burni in his writings on ancient Sindh did mentioned three scripts to be in vogue before the Arab invasion of Sindh viz. Malwari, Hinduvi & Ardhanagri. Yet confusion remains. One of the reasons of such confusion had been lack of historical evidences to counter verify the usage of Brahmi based scripts in Sindh. In 1958 a team led by researchers led by F A Khan did find some sort of evidences of the scripts used in ancient Sindh city of Bhanbhor which was approximately 40 Miles from the Sindh’s capital Karachi. Unfortunately the volume of such evidence is too little to construct the entire script as it existed in ancient Sindh. One of the main reasons needless to say had been the massive Arab Invasion of Sindh which swept all traces of Hindu culture. What Arabs destroyed never got rebuild.
In the context of Writing Systems in Sindh one can conveniently divide Sindh’s History in two parts. Viz. One before the Arab invasion and the other that followed after the massive upheaval that changed Sindh in all possible manner – culturally, socially and politically. Needless to say while almost all the North and west Indian Scripts could easily be traced to its brahmi , Sindhi never been that much fortunate. A close analysis revels more than once reason for loss of Historical loss of archeological evidence viz.
A) Post Arab Invasion there was an virtual slaughter of Sindhi Hindu Sadhus- the custodian of Learning in ancient India – Such void had a disastrous effect on Sindh which never could be reversed.
B) Post Arab invention every attempt was made to wipe out Hindu civilization & Culture including language from Sindh
C) In Kashmir & Punjab where even Hindus regained power from Muslims, the contemporary rulers reintroduced Brahmi based scripts but in Sindh Post Dahir Hindus never to could settle themselves and even those who did settle themselves after accepting Islam never bothered to reintroduce Sindhi Language in Sindh leave apart the Brahmni scripts
D) Ever since the massive Arab invasion Hindus were in a bitter struggle of existence. A struggle that continues even today in post-partition Sindh
