3. The Spread of Islam
Arab merchants traveled to many parts, many of them were Muslims, and they helped to spread their new religious beliefs. Arab armies also conquered neighboring regions. This was another way that Islam spread.
In 717, the Arabs attacked Constantinople, and even if they were not able to take the great fortress, most Christians who lived along the eastern and southern Mediterranean eventually converted to Islam. By the 700’s Muslims had also crossed to Spain. The Battle of Tours, in 732, when Arabs forces were defeated by European soldiers halted the Muslim advance into Christian Europe.

4. Reasons for Success
By that time, the three empires that might have stopped the Arab expansion (Roman, Byzantine and Persian) were either defeated or weakened. Also, a shared religion now united the arab peoples into one community. And once they began to work together the Muslims quickly grew powerful.

5. Under Muslim Rule Muslims tolerated other faiths
Christians and Jewish were allowed to pursue their own business.
Non-Muslim citizens had fewer rihts:
Forbidden to carry weapons
Could not serve in the military
Paid special tax

6. The Golden Age
The golden age of Muslim culture from about 800 to 1100 was a brilliant period of history. Great advances were made in mathematics, science, literature and architecture.

7. The Age of the Caliphs
One reason to the achievements was the wealth of the Arab world.
The wealth came from the many lands and from trade.
Baghdad was the capital during the golden age.
Traders from all over the world brought their goods to the caliph’s court.
The caliph was considered to be Muhammad’s successor.

Ibn Sina or Avicenna organized the medical knowledge of the Greeks and Arabs into the Canon of Medicine.

9. Achievements of the Golden Age Literature
Poetry was particularly important in the Islamic world
Sufis used poetry to teach their ideas and beliefs. They believed that they could draw close to God through prayer, fasting and living a simple life.
The most famous Sufi poet was Rumi.

10. The Ottoman Empire
After about 900, the power of the caliphs declined when Mongols killed the last caliph in Bagdad.
Much of the Muslim world was now controlled by Mongols and Turks.
The Ottoman ruler, or sultan, now held much of southeastern Europe and Turkey. Once again, much of the Muslim world was united under one ruler.
The Ottomans treated Jewish and Christians with tolerance which helped them strengthen the empire.
After Europeans defeated the Ottomans in 1683, the Ottoman Empire began a long decline.
