In the 19th century, Persian literature experienced dramatic change and entered a new era. The beginning of this change was exemplified by an incident in the mid-19th century at the court of Nasereddin Shah, when the reform-minded prime minister, Amir Kabir, chastised the poet Habibollah Qa'ani for "lying" in a panegyric qasida written in Kabir's honor. Kabir saw poetry in general and the type of poetry that had developed during the Qajar period as detrimental to "progress" and "modernization" in Iranian society, which he believed was in dire need of change. Such concerns were also expressed by others such as Fath-'Ali Akhundzadeh, Mirza Aqa Khan Kermani, and Mirza Malkom Khan. Khan also addressed a need for a change in Persian poetry in literary terms as well, always linking it to social concerns.
