Historical Trajectory
Phase I: Rise
The Samma dynasty was founded by Unar bin Babinah in 1351 when he defeated Sardar Hamir, the last Soomra Emir, and declared independence from the Delhi Sultanate. The Sammas established the Sindh Sultanate with its capital at Samanagar, present-day Thatta, and adopted the title of Jam, claiming descent from the legendary king Jamshid to legitimize their rule over the Sindhi Muslim population.
Phase II: Zenith
At its height the Samma dynasty presided over the Sindh Sultanate from Thatta, which served as a center of regional trade and Islamic culture along the lower Indus. The rulers patronized architecture and religious monuments, most notably a royal necropolis at Thatta that reflects the dynasty's investment in commemorative and funerary building traditions characteristic of medieval Sindhi Muslim courts.
Phase III: Decline
The Samma dynasty declined in the early sixteenth century as the Arghun dynasty, originally from Khorasan, extended its power into Sindh. The Arghuns displaced the Sammas and seized control of the Sindh Sultanate around 1520, ending nearly 170 years of Samma rule and integrating Sindh into a broader Persianate political sphere that would persist until Mughal expansion.
