[1] He was a Maqpon dynasty king who unified Baltistan and expanded its frontiers to Ladakh and western Tibet in the east, and in the west to the borders of Ghizar and Chitral.

While in Delhi, he married a Moghul princess named Gul Khatoon, the daughter of Akbar's uncle, Kamran Mirza.

During the reign of Ghazi Mir, the Ladakhis were driven out, not only from the Kharmang valley but from the entire district of Purik (Kargil), which was occupied by Ali Sher Khan, the heir apparent.

[5][6][7][verification needed] The king of Ladakh sued for peace and since Ali Sher Khan's intention was not to annex Ladakh, he agreed on the condition that the villages of Ganokh and Gagra Nullah (Grugurdo) should be ceded to Skardu and the Ladakhi king should pay annual tribute.

[citation needed] The incessant attacks on and plunder of villages in Roundu Baltistan, Dras, Gultari and Shingo Shigar by people from Gilgit, Chilas[1] and Astore, while he was preoccupied with the campaigns in Laddakh, forced Ali Sher Khan Anchan to march on Gilgit with an army worthy of his glorious name.

In Balti folk songs and stories Chitral is known by the name of Brushal and this Chinar tree is referred to as Brosho Shingial or the Chinal of Broshal, corrupted form of Bronshal.

In the folklore named after this Chinar of Brushal-Brosho Shingial, the exploits of Ali Sher Khan are enumerated and tribute is paid to the Anchan for his remarkable conquest and the boundary of his kingdom from Kargil from the east to Brushal or Chitral in the West and in doing so, the Balti people have also been allowed to share the tribute.

Ali Sher Khan is also credited with the construction of a dam on Satpara Lake, which irrigates Skardu.
