<P> Information about the early years of the Samma dynasty is very sketchy . We know from Ibn Battuta that in 1333 the Sammas were in rebellion, led by the Rajput founder of the dynasty, Jam Tamachi Unar . The Sammas overthrew the Soomras soon after 1335 and the last Soomra ruler took shelter with the governor of Gujarat, under the protection of Muhammad bin Tughluq, the sultan of Delhi . Mohammad bin Tughlaq made an expedition against Sindh in 1351 and died at Sondha, possibly in an attempt to restore the Soomras . With this, the Sammas became independent . The next sultan, Firuz Shah Tughlaq attacked Sindh in 1365 and 1367, unsuccessfully, but with reinforcements from Delhi he later obtained Banbhiniyo's surrender . The Samma dynasty overtook the Sumra dynasty and ruled Sindh during 1365--1521 . Around that time, the Sindhi Swarankar community returned from Kutch to their home towns in Sindh, and some settled empty land on the banks of Sindhu River near Dadu, Sindh . By the end of year 1500, nearly the entire Sindhi Swarankar community had returned to Sindh . This period marks the beginning of Sufistic thought and teachings in Sindh . </P> <P> For a period the Sammas were therefore subject to Delhi again . Later, as the Sultanate of Delhi collapsed they became fully independent . During most of period of Samma rule, the Sindh was politically and economically tied to the Gujarat Sultanate, with occasional periods of friction . Coins struck by the Samma dynasty show the titles "Sultan" and "Shah" as well as "Jam", the Jadeja rulers of western Gujarat also part of Samma tribe and directly descended from Jam Unar, the first Samma sultan of Sindh . Even the Chudasama Rajputs of Gujarat are also part of Samma tribe, who are still Hindu, and distributed in Junagadh District and Bhal Region of Gujarat . </P> <Table> <Tr> <Td> Sultans of Sindh Samma Dynasty "History of Delhi Sultanate" by M.H.
