Ajanic Renaissance is the term used today by many scholars to identify the cultural and artistic renovation which involved the Ajanic world from the middle of XI century onwards. Although there's no unanimity among scholars as for the exact timeline of this renaissance, the term has become of common usage for defining the whole period covering the XI-XV centuries.
Many historians have started to dissent from such wide chronological definition, and prefer to define the XV century as the Jahanid Renaissance (since its most important supporters where the shahs of the Jahanid Dynasty, and particularly Kalihaan IV), leaving the Ajanic Renaissance spanning from the XI to the XIII centuries.
What characterizes the Ajanic Renaissance is the rebirth of arts and cultural/intellectual activities in the Ajanic world at the levels of the ancient Ajanic Empire. Although, since the fall of the Empire in the V century, culture did not vanish, the political fragmentation and internecine conflict which followed it ensured that there were fewer possibilities for cultural and artistic patronage.
However, some forms of artistic renaissance were already to be seen under the so-called Badakian Empire of the VI-VII century, demonstrating that the rebirth of Ajanic culture was closely linked to political stability.
Since the XI century, patronage became again consistent, in particular in the fields of architecture and sculpture. However, soon this patronahe also shifted toward the commission of manuscritpts (particularly in the courts of Astana and Kusraw, which established massive libraries) and written works (particularly epic poems and tales of various nature).
Since cultural patronage was so strictly linked to political stability, it doesn't surprise that the Ajanic Renaissance happened in a period when the Shahdom of Astana, ruled by a renewed Jahanid Dynasty, was managing to restore order in the Ajanic lands, particularly subjugating the independent beyliks and emirates which dominated the south of Tarajan and the course of the Shalimar river. This political restoration of Astana egemony (although exercised in a form very different from the imperial one) was the fruit of the work of shahs like Ardashir IV (957-980) and Ardashir V (990-1050), who made many military expeditions against the south, and saw its apogee under the reigns of Esmail I (967-983), Esmail II (983-990), and Ardashir V (990-1050). The latter's reign, known to be the longest one in Ajanic history, saw the definitive stabilization of a modus vivendi between the Shahdom and the many beyliks of the south, now firmly in the orbit of Astana.
Clearly, this was the best opportunity for the cultural and artistic renaissance, and patronage was strongly exercises not only by the Shahs, but also by the beys themselves, who found in mecenatism a way to improve their prestige and legitimacy in face of the loss of political indipendence.
