Al sultan al mutawwaqil ala allah al-fath al-kamru wa’alkamta bi-inayat allah ala al-dunya wa’al din abu al Muzaffar husain shah al sultan fath kamta, Rev. kalima shahada with mint name & date, multifoil decorative borders, centrally struck, extremely fine with a very high relief, rare. Note: Ala al-din Husain Shah of the Bengal Sultanate achieved a significant victory over the Kamata Kingdom (Kamru and Kamta) in a war that culminated in 1498 AD with the defeat and imprisonment of the last Khen King, Nilambar. All Tanka dated AH 900 were likely struck to commemorate the conquest of Kamta and Kamru. However, the Bengal Sultanate's rule over Kamata and Kamrup was very short-lived, lasting less than a decade. A confederation of local Assamese chieftains (Baro-Bhuyans) rose in revolt, capturing and killing the Governor of Kamta, Shahzada Danyal (Husain Shah's eldest son), and his officers. This effectively ended the Sultanate's direct control over the area within a decade (around 1509 AD). The region then experienced an interregnum until the rise of the Cooch dynasty.
