Al-Sultan al-Adil / Qulna Khan / Khalad Mulkeh ("The Just Qulna Khan, may his rule last") // Zarb fi balad Gulistan ("Struck in the city of Gulistan"), 760 in a number of lines. Dated to 760 AH/1359 AD. 16mm, 1.50 grams. Mint of Gulistan. Sagdeeva #285.

The location of Gulistan is not completely certain - the current consensus is that it was located near the site of Tsarevskoe Gorodishche on lower Volga, in modern Russia.

Qulna (or Qulpa, as he is named in the Russian chronicles), briefly ruled the Golden Horde in 760-761 AH (1359-60 CE) for about six months, was a descendant of Tangkut (the sixth son of Jochi, and thus part of the extended Borjigin royal lineage. His reign occurred during a period of intense political fragmentation following the death of Khan Berdi Beg, when rival factions and noble clans vied for power in rapid succession. Little is known about Khyzr's policies or achievements, and his time as khan was short and contested and he was murdered by his successor, Nawruz. His emergence reflects the deepening instability of the Golden Horde in the mid-14th century, as central authority collapsed and multiple Jochid branches struggled for control.
