Hasan Beyzâde Ahmed Paşa (d. 1636/7) was son of the reisülküttab Hasan Bey. After a medrese education, he entered the palace bureaucracy in the early 1590s and served under various viziers and commanders, taking part in quite a few of the campaigns in the Habsburg front. In 1600 he became reisülküttab himself for a while, and then continued to serve in various financial posts in Istanbul and the provinces.
His main work is his chronicle, Zeyl-i tacü’t-tevarih, written in various stages between 1628 and 1635 and covering the period from Suleyman’s to Murad IV’s reign. The work presented here is the political treatise, Usûlü’l-hikem fi nizâmi’l-âlem (“Elements of wisdom for the order of the world”).
