Saptagram

Saptagram, or Satgaon, was a river port and administrative centre on the Saraswati in southern Bengal. In 1337 Izz al-Din Yahya governed it for the Delhi Sultanate.

On Yahya’s death in 1338, his officer Shamsuddin Ilyas Shah seized Saptagram and used it as a base to unite Bengal. In 1565 Maharaja Rudranarayan of Bhurshut took the port from the Pathans, who recovered it in 1592. By then the Saraswati was silting up, and trade shifted to Hooghly and later Calcutta, leaving the old port deserted.
