The Ashtarkhanid Rulers of Bukhara  Iraj Bashiri  Copyright,
Bashiri, 2000  Stemming from the line of Jochi Khan, Chingiz
Khan's eldest son, the Ashtarkhanids ruled in Ma Wara' al-Nahr
(Transoxiana) and Khurasan between 1599 and 1753. Between 1380
when the Golden Horde was dissolved and the annexation of the
region to the north of the Caspian by Russia in 1552, they had
ruled Astarakhan complementing the territories of the Crimean
Tatars, and the Khanate of Kazan. Now they had their eyes on the
rich lands of the Shaibanids to the south.  Around the year
1599, one of the Ashtarkhanids, known variously as Janimuhammad
or Janibek Sultan, emigrated to Bukhara. There he married into
the ruling family of Bukhara, the Shaibanids, another line
descending from Jochi Khan. The establishment of this new family
tie further strengthened Janibek Sultan's eligibility for the
rulership of the kingdom.  Upon the death of Abdulmu'min, the
last Shaibanid ruler, the Bukharans offered the rulership of
their kingdom to Janibek Sul
