Read the passage below and answer the following question.
"It is necessary for the sultan to inquire into the state of the treasury and the conduct of his governors... In these times, although the supreme authority of the Caliph in Baghdad is formally acknowledged in the Friday sermon (*khutbah*) and on the coinage, the actual administration of the provinces, the collection of revenues, and the defense of the frontiers have passed into the hands of the Turkic commanders and regional sultans. Yet, even as the empire of the faithful is divided into many principalities, the colleges (*madrasas*) are filled with students, libraries are expanded by the patronage of regional courts, and scholars journey from Nishapur to Cairo under the protection of local rulers who compete to sponsor the sciences."
— Nizam al-Mulk, Seljuk vizier, *Siyasatnama* (*Book of Government*), late eleventh century
