Samma

The Samma were a Muslim Sindhi dynasty rising around Sehwan in the Indus valley. Their chiefs used the title jam; in 1333 Ibn Battuta found them in revolt under Jam Tamachi against the Soomras.

After overthrowing the Soomras, Jam Unar secured independence when Delhi’s Sultan Muhammad bin Tughluq died in Sindh in 1351. Delhi briefly restored tribute through expeditions in 1365 and 1367. At Thatta, Jam Nizamuddin II patronized the Makli necropolis, while his vizier Darya Khan defeated the Arghuns near Sibi. Succession fighting followed, and Shah Beg Arghun overthrew the last jam in 1519.
