Today, Baghdad is a city that would be recognized as the center of war and political conflict. However, by 800 AD it was a famous educational metropolis, attracting scholars, scientists and artists from across the Muslim world. Much of the scientific and philosophical knowledge of the modern world has its roots in the Abbasid Caliphate and its capital Baghdad. Bayt al-Hikma, or the House of Wisdom, was founded by the caliph Harun al-Rashid and officially established by his son al-Mamun in early medieval Europe. Bayt al-Hikma was a distinguished institution where a remarkable group of scholars undertook the task of translating all the scientific and philosophical works of the classical era into Arabic, which would be incorporated into Islam itself. The call to the great library enabled the preservation of knowledge from the classical era, responsible for the European renaissance and many of the advances on which the modern world depends. Over the next four to five hundred years, alchemists, scientists, scholars, writers, men of letters, and copyists learned, read, wrote, and translated manuscripts originally written in foreign languages ​​for a specific purpose. The Bayt al-Hikma was modeled after the Sasanian Imperial Library, with the same religious motivation. Muslim rulers have long relied on the study of astronomy to calculate prayer times and the direction Mecca was in relation to a city. The beginnings of the Muslim empire's deep curiosity for knowledge can be traced back to the need to implement the five pillars of Islam. Religious periods like the month of Ramadan, or the month of Hajj had great importance in Muslim empires, like middle of paper......o mathematics, the Banu Musa brothers were great engineers who perfected the wheel hydraulics and oversaw the construction of underground canals called qanats, on which Baghdad then expanded. Unlike the great Greek philosophers before them, Abbasid scholars established the importance of scientific observation and experimentation. As for philosophy, Muslim scholar-translators studied classical texts, but solved problems using their own method of scientific observation rather than the pure logic for which Aristotle was famous. The Muslim philosophers of Bayt-al Hikma used reasoning and knowledge of Greek texts to support their own philosophies and blend Greek and Islamic ideas. Perhaps the first philosopher of Islam, al-Kindi is rightly considered the scholar most responsible for mixing Greek philosophy with the philosophy of Islam..
