The most important source of history is the historical accounts written in the administrative language Persian, and known as tawarikh. The authors wrote about events and gave administrative advices to the Sultan. However, it was mainly written to please the rulers and gain rewards, so it gives only a partial picture of the period.
The authors lived in the cities and were quite unaware of the realities of rural areas. Sometimes, the authors also penned down their displeasure about certain decisions.
