Tarikh-i Bayhaqi

Tārīkh-i Bayhaqī (Persian: تاریخ بیهقی; lit. 'Bayhaqi's History') is a history book written by Abul-Fazl Bayhaqi, in Persian, in the 11th century CE. Much of this voluminous work is lost, but it remains one of the most important sources concerning the history of the Ghaznavid Empire.

The work is more than a history book. Its detailed descriptions and unique style of narration of the historical events has made it similar to a "historical novel" and one of the masterpieces of Persian literature. The work was written at the Ghaznavid chancellery in order to frame the Turkic-origin Ghaznavid rulers in line with Iranian kings.
