Dollah Darya Khan

Jam Mubarak Khan Qabulio Sammo also known as Darya Khan Lashari and Darya Khan Qabulio Sammo(دريا خان قبوليو), was a general of the Samma Dynasty of Sindh, a statesman and regent at the court of Samma ruler Jam Feroz.

According to some sources, Darya Khan belonged to Qabooliyo tribe of Samma. According to another tradition, however, Darya Khan was Lashari Baloch and was the adopted son and prime minister of Jam Nizamuddin II who defeated the Arghun army in the Battle of Jalwakhir near Bibi Nani in the Bolan Pass. This victory made Darya Khan Sammo, the 'Dollah' (Hero) of Sindh. On his deathbed, Jam Nizamuddin, entrusted to Darya Khan the care of his kingdom, of his treasures, his family, and his son Jam Feroz. Darya Khan was killed in action in the Battle of Fatehpur when an arrow struck his throat, thus ending the reign of Jam Feroz as an independent ruler.

Military service
In the days of Mongol, Sultan Hussain Mirza Baiqra, of Khurasan, on complaints of the merchants of Central Asia (Herat and Qandhar), that they were looted by Sindhis, the Sultan sent an armed expedition to the Sind border which, after initial raids returned to their country. A declaration of victory was issued in Herat in 892 A.H. (1487 AD). It states that the infidels (Sindhis), aware of Mongol movements, collected a large army and wanted to make a surprise attack. Still, the Islamic forces (Mongols) learned of it and made offensive attacks, killing many of these Hindus (forces of Jam Nizamuddin). As a result of this success, a declaration of victory was issued.

This may have been an attack on the Sindh border without any results. Amir Zul Noon Arghoon was then Herat's Naib at Qandhar. He seems to have despatched his son Shah Beg on this expedition. The latter captured the Sibi Fort from Jam Nizamuddin's agent Bahadur Khan and installed his brother Sultan Mohammad, who later on was defeated and killed by Mubarak Khan (Darya Khan Dullah) near Jalwagir in Bolan Pass, close to Bibi Nani.

After this incident, the Mongols did not turn up in Sindh during the life of Jam Nizamuddin. At that time, the Mongol troops had advanced as far as Chanduka, Sardecha, and Kot Machhi. Still, after being expelled by Darya Khan, they never returned during Jam Nizamuddin's lifetime.

Death of Jam Nizamuddin Samma after 48 years of rule of Sind and was succeeded by his son Nasiruddin Abul Fatah Feroz Shah-II. At that time, Jam Feroz had neglected the affairs of the state and refused the advice of Darya Khan, who had to retire to his Jagir in the village Ghaha (Kahan near Sehwan and these failures brought his defeat at the hands of Salahuddin who thus became the ruler of Sind. Feroz Shah, along with his mother Madina Machhani went over to Ghaha to Darya Khan, who at the request of Madina agreed to help, and collected troops from Sehwan, but got the first setback at the hands of Haji, the Minister of Jam Salahuddin. As luck would have it the Minister's letter about the success of the initial battle addressed to Jam Salahuddin fell in the hands of Darya Khan, who had it replaced, conveying Salahuddin that the Minister's forces had been defeated. He should have abandoned Thatta. This was quickly done. Darya Khan then moved Feroz Shah to Thatta and installed him on 1st Shawwal, 918 A.H. (1512 A D. 12 October). Salahuddin then returned to Gujarat. He had remained in possession of Thatta for about eight months and must have collected a large sum of money from Thatta and organized another battle.

Last days of Darya Khan
There are different versions of the last days of his life.

Tahiri states: that the courtiers being jealous of his power and position persuaded Feroz Shah to crush him, but the latter finding himself incapable avoided any direct conflict; so they approached Feroz's mother Madina Machhani advising her to invite the Mongols and Arghuns to free Sindh from the power of Darya Khan. According to this plan, Madina invited Shah Beg from Qandahar. Shah Beg took the Baghban-Sehwan route and encountered Darya Khan near the 'Khan Wan' canal which he had himself built to irrigate the lands of village Sankorah (Sakro) and other areas (of Thatta and Sakro Talukas). Darya Khan was killed while fighting bravely when an arrow hit him in the throat. Feroz Shah kept aloof. Masumi on the other hand reports:

Some Mongols had migrated to Thatta and entered the service of Jam Feroz who had assigned a separate quarter to them called Mongol Pura. One Mir Qasim Kaibakian Arghoon encouraged and induced Shah Beg to undertake the conquest of Thatta and, therefore, Shah Beg made reparations and was first opposed near Talhati (Talti) by Matan Khan (Motan Khan) son of Darya Khan, but avoiding them Shah Beg reached Khanwah located 6 miles north of the city of Thatta, crossed the river at a point where it was shallow and reached near Thatta. Darya Khan left Feroz Shah in the city and came out to fight a fierce battle, which he lost, and was captured by Tingari Birdi Qabtasal and put to sword along with the other Samma soldiers. Jam Feroz took to flight. Beglar Nama states that:he was captured and killed.

Zafar-ul-Walih states: he was called by the Arghoons to discuss peace terms and treacherously murdered.
