Madrasse of Nadira-Divan-bigi (1620) in Bukhara
Divan-begi is a title that designated the post right after khan in the Bukhara khanate. Nadir Divan-begi held this position during the reign of Imam Quli-khan (1611-1642), the strongest khan of the Ashtarkhanid (Janid) dynasty (established in 1599). The rulers of Janid dynasty was alien to powerful Shaibanid feudal lords, therefore Imam Quli-khan hardly retained his power by force. The devotion to Islam tradition in the state under Janid dynasty was pale before the eagerness of the time of prominent Shaibanid khans. These two important peculiarities of the power were soon expressed in remarkable architecture tendency. In 1619 Yalantush-biy who virtually independently governed Samarkand had begun the construction of grand madrasah (Sher-Dor Madrasah). The rich colored finishing and the depiction of sun, tigers and antelopes tell of a pioneering approach to artistic expression, unique in the Islamic world.
The Nadir Divan-Begi Madrasah (1622/23)

In three years Nadir Divan-begi followed Yalantush-biy by construction of his own revolutionary structure (Nadir Divan-Begi Madrasah). Originally Nadir Divan-begi intended the building to be a caravanserai (not that it was allowed to portray human or animal figures on them either but it was marginally better than on a madrasah). But at the inauguration ceremony, Imam Quli-khan unexpectedly proclaimed the supposed caravanserai is to be a madrasah. So Nadir Divan-begi was obliged to rearrange the caravanserai, by adding on to the front the loggias and angular towers. He also constructed an additional storey with cells (hujras). At the same time the madrasah does not have a lecture room!

The entrance portal has depictions of 2 phoenix birds, 2 misshapen white deer and a "man-in-the-sun" face.
