1 Tanka - Ala al Din Husain Shah

Ala al-Din Husain Shah ruled Bengal for an unusually long stretch by sultanate standards — over two decades — and is regarded by Bengali historians as one of the most capable rulers the region produced before Mughal absorption. He expanded the sultanate to its greatest territorial extent, briefly controlling parts of Assam and Orissa, and his court became a notable center of Bengali literary production. The silver tanka series issued across his reign shows considerable variation in die workmanship, reflecting output from multiple minting centers operating simultaneously.
