Funding of science existed in many Muslim empires outside the Abbasids and continued even after the Mongol invasions into the Middle East. Results of patronage in Medieval Islamic areas include the House of Wisdom in Baghdad, the Al-Azhar University in Cairo, Bimaristans across the Middle East and Persia, and famous observatories, such at that of Ulugh Beg in Samarqand. It is also significant to note that later Muslim empires (Ottomans, Safavid, Mughal empires) also supported science in their own ways, even though there scientific achievements were not as prominent on a global level.[7][8]
