Aleh Booyeh was one of the strongest Iranian dynasties. They ruled over an extremely vast area of the Islamic civilization - including Iran and Iraq - for over a century. The three sons of Booyeh, i.e. Au, Hasan, and Ahmad, were Shiite and they therefore influenced Shiism significantly. For instance, they contributed to Imam Hossein s Mourning Ceremony, to the Al-Ghadir Celebration, to the Karbala pilgrimage, etc. They also helped Shiite scholars spread and develop their ideas.
Aleh Booyeh rulers were also quite interested in Arabic language, literature, and culture and many of them were poets as well (such as Adad Al-Dulah). Arabic literature, therefore, reached its peak under their rule during the fourth century A.H.
Aleh Booyeh rulers appointed great authors to administrative positions. These ministers, such as Abolfadl Ibn Ahmid, were often leaders of literary movements and helped to revive the, literature of their period. They also supported and helped many men of letters and founded some of the largest libraries of their age. In general, the Aleh Booyeh dynasty caused an outstanding development in the prose and verse of that century.
