آل بویه was a Persian dynasty that ruled over parts of Iran from the 10th to the 11th centuries. They were originally of Daylamite origin and gained power after the decline of the Samanid Empire. The dynasty is known for its contributions to Persian culture, literature, and architecture, as well as for promoting the use of the Persian language in administration. The rulers of آل بویه were significant in establishing a degree of autonomy in the region, often acting as vassals to the Abbasid Caliphate. They played a crucial role in the political landscape of the time, fostering a period of cultural revival and stability in Iran.
