Nadir Divan-begi Madrasah is a part of the architectural complex located round well-known Lyabi-Hauz in Bukhara. The madrasah building, as well as khanaka nearby, were named after vizier Nadir by whose order they were constructed. Vizier Nadir served at a court yard of one the strongest and powerful representatives of Ashtarkhanid dynasty Imamkuli-khan, who ruled in Bukhara in 1611-1642. The board of Imamkuli-khan was one of the most stable and relatively peaceful for the whole history of Ashtarkhanids in Bukhara. It was time when governors paid attention not only to constant wars, but also to town-planning.
