1 Tanka - Nasir al-din Nusrat

Nasir al-din Nusrat Shah ruled Bengal during a period of genuine political consolidation, having succeeded his father Alauddin Husain Shah — founder of the Husainid dynasty and arguably the most capable sultan Bengal produced. Nusrat continued his father's policies of administrative stability and patronage, but his reign ended violently: he was assassinated in 1532 by Afghan nobles, part of the broader turbulence that would eventually open Bengal to Sher Shah Suri's expansion.

Bengal's silver tankas of this period drew on local river sources, the region's alluvial deposits providing reasonably consistent metal supply through the early sixteenth century.
