Abstract
Bayt al-Hikmahs are centers of science and culture where translations and high-level scientific researches were carried out in the Middle Ages. Among the Bayt al-Hikmahs, which have an important place in the history of Islamic science and thought, especially the Bayt al-Hikmah established in the Abbasid period and the Bayt al-Hikmah established in the Aghlebid period comes to the fore. In addition to being an acadenic center, said Bayt al-Hikmah also gained importance esecially with translation activities. These institutions, in which a large number of scientists were trained and researched actively, had a special importance in shaping the history of medieval Islamic thought.It is known that the first Bayt al-Hikmah in Islamic history was established during the Abbasid State period. The Abbasid Bayt al-Hikmah set an example for the later Bayt al-Hikmahs. One of these examples is Bayt al-Hikmah of Aghlabid, which was established in the Aghlabid period. Both of the Beytü'l-Hikme poses similarities in terms of their establishment purpose and functioning. In this article, a comparison of both Bayt al-Hikmah’s will be made in terms of their foundation, structure, functioning, scholars and their influence in the history of Islamic thought.
