Arabia before Islam and the rise of Islam
Arabia was a land of deserts and oases. Tribes lived by herding and by trade along caravan routes. Mecca was a trade and pilgrimage town. Muhammad was born in Mecca about 570. In 610 he began to share the message of one God, which Muslims believe was revealed to him. In 622 he moved with his followers to Medina (the Hijra, the start of the Islamic calendar). He returned to Mecca and died in 632.
The five pillars are shahada (declaration of faith), salat (prayer), zakat (charity), sawm (fasting in Ramadan) and hajj (pilgrimage to Mecca).
The caliphs and expansion
After Muhammad, leaders called caliphs ruled. The first four (Abu Bakr, Umar, Uthman and Ali, 632–661) are called the Rashidun, 'rightly guided'. Within a century Arab armies and traders reached from Spain in the west (711) to Sindh in the east (711). Reasons: weak neighbouring powers, strong faith and unity, skilled cavalry, and fair treatment that often kept local people's lands and, for many, their faith in return for tax.
Umayyads and Abbasids
The Umayyads (661–750) ruled from Damascus and used Arabic as the language of government and coins. In 750 the Abbasids took over. In 762 they founded Baghdad, a round city by the Tigris, which became the greatest city of its time. Over time many regions had their own rulers, and in 1258 the Mongols captured Baghdad, ending the Abbasid caliphate there.
Arab culture and learning
At the House of Wisdom in Baghdad, scholars translated Greek, Persian and Indian books into Arabic and added their own work. Al-Khwarizmi wrote on algebra and spread the Hindu–Arabic numbers. Ibn Sina wrote a famous medical book. Ibn al-Haytham studied light. Astronomers improved the astrolabe. Paper-making spread, so books became cheaper. Beautiful domed mosques, geometric patterns and calligraphy marked the art. These ideas later reached Europe and helped the Renaissance. Try it: write the number 2025 using the digits 0–9 and think how hard it would be without zero.
Key formulas and definitions
- Muhammad: born c.570; Hijra to Medina 622; died 632
- Five pillars: shahada, salat, zakat, sawm, hajj
- Rashidun caliphs: 632–661; Umayyads (Damascus): 661–750
- Abbasids (Baghdad, founded 762): 750–1258
- House of Wisdom: translation + science + numerals 0–9
Worked examples
1. Why did Mecca grow important before Islam?
It lay on caravan routes, so traders passed through, and it held a sacred place that pilgrims visited. Trade and pilgrimage made it rich.
2. Why did the Abbasids build Baghdad as a new capital?
It stood on the Tigris river with good land and trade routes, near the heart of their Persian and Iraqi supporters. Moving away from Damascus also marked the start of a new dynasty.
3. How many years did the Umayyad dynasty last (661 to 750)?
750 − 661 = 89 years.
Common mistakes
- Mixing up the capitals: Damascus for the Umayyads, Baghdad for the Abbasids.
- Thinking the rings or maps show fixed borders. Reach grew and changed over time.
- Saying numbers 0–9 were invented by Arabs. They came from India; Arab scholars spread them.
- Counting the pillars wrong: there are five, not four or six.
