The Battle of Jalwakhir (natively, Jalūkīr ; جلوڪير جي جنگ) also known as Joolow Geer, was a battle held at the south of present-day-Quetta, fought in 1486 CE/892 AH between Samma Khan-i-Azam Jam Mubarak Khan alias Darya Khan and the invading Mongol forces under Shah Beg Arghun son of Zu'n-Nun Beg Arghun, governor of Kandahar, Farah, Zamindawar, and Ghor, on behalf of Sultan Hussain Bayqara.

Shah Beg had earlier captured Siwi, Ganjabah, and Fatehpur by defeating Samma forces under Jam Nizamudin II's Gumashta (Governor/Officer), Bahadur Khan, in 1486 CE/892 AH.

[2][3][4][5] The great Arghun chief Zu'n-Nun Beg, who, towards the end of the fifteenth century, was appointed by Sultan Hussayn Mirza of Herat to the Governorship of Qandahar, finding the territory under his control insufficient to satisfy his needs and his ambition, proceeded to enlarge his borders.

Out of his fear, the Shah Beg Arghun attacked to Sindh through his brother Mirza Sultan Ahmed who looted the forts of Chandka, Mandeja and Machi's.

[6] Mubarak Khan came upon the Arghuns at Jalugir, a place in the Bolan Pass, near Bibi Nani, inflicted a crushing defeat on them, and killed their leader, Muhammad Beg.
