2. Muhammad had not named a successor or instructed his followers how to choose one. The Muslim community elected Abu-Bakr as the new leader and Muhammad’s first successor (first caliph). He had been a loyal friend of Muhammad, a man respected for his devotion to Islam. Under Abu-Bakr, the collection of Mohammad's revelations were recorded in the Qur’an.

3. “Rightly Guided” Caliphs Abu-Bakr and the next three elected caliphs—Umar, Uthman, and Ali—all had known Muhammad and supported his mission. For this, they are known as the “rightly guided” caliphs. By 750, from the Atlantic Ocean to the Indus River, the Muslim Empire stretched 6,000 miles—about two times the distance across the continental United States. PP Design of T. Loessin; Akins H.S.

4. Treatment of Conquered Peoples Many conquered peoples chose to accept Islam. They were attracted by the appeal of the message of Islam, as well as by the economic benefit for Muslims of not having to pay a poll tax. Christians and Jews, as “people of the book,” were allowed to practice their faiths freely and even received special consideration. In practice, tolerance like this was extended to other groups as well. PP Design of T. Loessin; Akins H.S.

5. Sunni–Shi’a Split In the interest of peace, the majority of Muslims accepted the Umayyads’ rule. A minority did continue to resist, and around some of these groups an alternate view of the office of caliph developed. In this view, the caliph—the person most responsible for spreading Muhammad’s message—needed to be a relative of the Prophet.

6. Sunni–Shi’a Split This group was called Shi’a, meaning the “party” of Ali. Those who did not outwardly resist the rule of the Umayyads became known as Sunni, meaning followers of Muhammad’s example. Another group, the Sufi (SOOfee), reacted to the luxurious life of the Umayyads by pursuing a life of poverty and devotion to a spiritual path. They tried to achieve direct personal contact with God through mystical means, such as meditation and chanting.

7. The Umayyads and the Abbassids Set up dynasty that ruled until 750 Moved capital to Damascus Conquered lands from Atlantic to the Indus Valley Relied on local officials to govern the empire, while the Umayyads themselves lived in great luxury. Faced economic tensions between wealthy and poor Arabs Split in Islam occurs during their reign – between Sunni, Shi’a, Sufi. Overthrew the Umayyads in 750 Moved capital to Baghdad Ended Arab dominance and helped make Islam a universal religion Empire of the caliphs reached its greatest wealth and power through strong trade network. Muslim civilization enjoyed a Golden Age Difficulty controlling vast empire. These powerful caliphates ruled the Islamic world, expanded the Arab empire, and brought about a golden age in Muslim civilization. UMAYYADSABBASSIDS 2 PP Design of T. Loessin; Akins H.S.

8. Muslim Trade Network The two major sea-trading zones—those of the Mediterranean Sea and the Indian Ocean—linked the Muslim Empire into a world system of trade by sea. The land network connected the Silk Roads of China and India with Europe and Africa. Muslim merchants needed only a single language, Arabic, and a single currency, the Abbasid dinar, to travel from Córdoba, in Spain, to Baghdad and on to China. PP Design of T. Loessin; Akins H.S.

9. Muslim Trade Network To encourage the flow of trade, Muslim moneychangers set up banks in cities throughout the empire. Banks offered letters of credit, called sakks, to merchants. A merchant with a sakk from a bank in Baghdad could exchange it for cash at a bank in any other major city in the empire. In Europe, the word sakk was pronounced, “check.” Thus, the practice of using checks dates back to the Muslim Empire. PP Design of T. Loessin; Akins H.S.

Medicine, math, and science Arabic numerals, the importance of zero (10 digits) Developed algebra, trigonometry in astronomy Charted stars, comets, and planets / constellation charts The astrolabe PP Design of T. Loessin; Akins H.S. The Astrolabe played a pivotal role in history. The astrolabe was highly developed in the Islamic world by 800 and was introduced to Europe from Islamic Spain (Andalusia) in the early 12th century. It was the most popular astronomical instrument until about 1650, when it was replaced by more specialized and accurate instruments. It is doubtful the European explorers could have ever launched the great Age of Discovery without this device. Astrolabes are still appreciated for their unique capabilities and their value for astronomy education.

How did the Arabs, who had no direct contact with the science and learning of Classical Greece, come to be the inheritors of the classical tradition? The answer appears to be the Umayyad dynasty located in Damascus. They had an interest in things Greek, employed educated Greek- speaking civil servants extensively, and sought to preserve Greek science.
