It was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. The most prominent example of this is with the Translation Movement of the ninth century that was facilitated by early Abbasid Caliphs.[3] Other wealthy patrons also supported this movement and accelerated the process of acquiring, translating and interpreting ancient works of philosophy and science. Funding for translation was ongoing throughout the reign of certain caliphs, and it turned out that certain scholars became experts in the works they translated and in turn received further support for continuing to develop certain sciences.
