According to legends, the wall existed during
Umayyad rule and later under the
Abbasid rule. The Soomro tribe inhabited the fort and later the
Samma tribe positioned large infantry formations inside the fort. The
Mughal Emirs armed the walls of the fort with cannons and muskets. They were the first to renovate the entire structure. The
Kalhora tribe later gained control of the fort, and finally the
Talpurs saw the fort as a strategic asset especially during the reign of
Mir Fatih Ali Khan Talpur, until they were defeated and overthrown by the British Empire, in 1843 AD. The first radiocarbon date from charcoal included in the mortar of a collapsed pillar lying overturned in the riverbed at Sann (Eastern) Gate, Ranikot, confirms that at least this sector of the fort was built, or repaired, between the beginning of the 18th century and the beginning of 19th century, that is between the beginning of the Kalhoras and the beginning of the Talpurs rule. The present note, without positively solving the much debated issue of the age of the fort, points to a new line of research on the topic, which deserves future work, in order to collect more organic material for absolute dating. An Acacia charcoal sample collected from the above exposed surface was sent to Groningen Radiocarbon Laboratory (NL) for AMS dating. It yielded the following result 160±30 uncal BP (GrA-44671). Although its calibration is rather problematic, given that the curve at this point is highly fluctuating with several interceptions, most probabilities indicate that the pillar was erected between cal AD 1720 and 1828 (47.6% at 2 sigmas, according to OxCal 4.10: BRONK RAMSEY, 2009),although another interception suggests a much more recent date (fig.6). ==See also==
