Removed from Current NCERT Edition — This chapter was part of the original Themes in World History (Class XI) but was deleted during the NCERT rationalization of 2022–23. The removal was politically controversial — critics noted it coincided with removal of Mughal chapters from Class XII. It remains essential for UPSC GS1 (Medieval World History) and GS2 (India-West Asia relations).

This chapter covers the rise of Islam from 570 CE to approximately 1200 CE — the emergence of the faith, the caliphate system, Arab conquests, the golden age of Islamic civilisation under the Abbasids, and the Crusades.


1. Pre-Islamic Arabia

Pre-Islamic Arabia (called the Jahiliyya — age of ignorance in Islamic tradition) was characterised by:

  • Tribal organisation; no centralised state
  • Polytheistic religion; the Kaaba in Mecca housed 360 idols
  • Mecca was an important trading hub on the incense route from Yemen to Syria
  • Quraish tribe controlled Mecca and the Kaaba

2. Rise of Islam

Event Date Significance
Prophet Muhammad born 570 CE Mecca, Quraish tribe
First revelation 610–612 CE Cave of Hira; Gabriel appears to Muhammad
Hijra (migration) 622 CE Mecca → Medina; start of Islamic (Hijri) calendar
Conquest of Mecca 630 CE Muhammad returns; idols removed from Kaaba
Death of Prophet 632 CE No male heir; succession crisis begins

Five Pillars of Islam

  1. Shahada — Declaration of faith: "There is no God but Allah, and Muhammad is His Prophet"
  2. Namaz (Salah) — Five daily prayers facing Mecca
  3. Roza (Sawm) — Fasting during Ramadan
  4. Zakat — Almsgiving (2.5% of savings to the poor)
  5. Hajj — Pilgrimage to Mecca (once in a lifetime if able)

Key Terms

Term Meaning
Umma The community of all Muslims, founded by Prophet Muhammad
Khalifa (Caliph) Successor to the Prophet; political and religious leader
Sharia Islamic religious law derived from Quran and Hadith
Hadith Recorded sayings and actions of Prophet Muhammad
Ulamas Islamic religious scholars
Sufis Mystics seeking personal union with God through ascetic practice
Dhimmis Protected non-Muslim subjects (Christians, Jews) under Islamic rule
Jaziya Poll tax paid by Dhimmis in lieu of military service

3. The Caliphates

Rashidun Caliphate (632–661 CE)

The first four caliphs — Abu Bakr → Umar → Uthman → Ali — are called the Rashidun (rightly guided). Key conquests under Umar:

  • Syria (636 CE), Iraq (637 CE), Iran (641 CE), Egypt (642 CE)

The Sunni-Shia split originated here: Shias believe the caliphate should have passed directly to Ali (Prophet's cousin and son-in-law); Sunnis accept Abu Bakr's succession as legitimate.

Umayyad Dynasty (661–750 CE)

  • Founded by Muawiya; capital at Damascus
  • Empire expanded to Spain (711 CE) in the west and Sindh (712 CE) in the east
  • Arab aristocracy dominated; non-Arab Muslims (mawali) had inferior status — a source of resentment
  • The Abbasid Revolution (750 CE) overthrew the Umayyads, massacring most of the family (one prince escaped to Spain)

Abbasid Dynasty (750–945 CE)

  • Founded by Abu-ol-Abbas; capital moved to Baghdad (founded 762 CE)
  • Baghdad's population reached ~1 million by 800 CE — largest city in the world outside China
  • Golden Age of Islamic civilisation — translation movement, science, philosophy, medicine flourished
  • Buyids (Shia Persian dynasty) captured Baghdad in 945 CE — Abbasid caliphs became figureheads
  • Saljuq Turks restored Sunni dominance in Baghdad (1055 CE); Tughril Beg received title "Sultan"
  • Mongols sacked Baghdad in 1258 CE — end of Abbasid caliphate

Fatimid Caliphate (969–1171 CE)

  • Shia; ruled Egypt from 969 CE; founded Cairo
  • Controlled North Africa, Sicily, and parts of the Levant
  • Competed ideologically with the Sunni Abbasids

4. The Crusades (1095–1291 CE)

Crusade Date Key Event
First Crusade 1095–1099 Pope Urban II's call; Jerusalem captured 1099
Saladin recaptures Jerusalem 1187 Kurdish Muslim commander Saladin defeats Crusaders
Third Crusade 1189–1192 Richard I (Lionheart) vs. Saladin; stalemate
Mamluks expel Crusaders 1291 Acre falls; last Crusader presence removed

Cause: Pope Urban II called the First Crusade in 1095 to recover Jerusalem from Muslim control and assist the Byzantine Emperor against Saljuq Turks.

Significance for UPSC: The Crusades represented a prolonged contact and conflict between European Christian and Islamic civilisations, with significant cultural exchange alongside the violence — Islamic science, mathematics, and philosophy entered Europe through this contact.


5. Economy and Society

Agriculture

  • New crops introduced across the Islamic world: cotton, oranges, bananas, watermelons, spinach, brinjals (aubergines)
  • Iqtas — agricultural territories assigned to soldiers/officers as salary (similar to jagirs in Mughal India)

Trade and Commerce

  • Gold dinars and silver dirhams were the standard Islamic coins
  • Baghdad was a hub of the Indian Ocean trade network
  • Arabic numerals (from India via Arab scholars) revolutionised commerce

Urbanisation

  • Great cities: Baghdad, Cairo, Cordoba, Samarkand
  • Caravanserais — rest houses for merchants along trade routes
  • Bazaars — organised market areas in Islamic cities

6. Islamic Learning — The Golden Age

The Abbasid period (~750–1258 CE) saw a massive translation movement: Greek, Persian, and Indian texts were translated into Arabic at the Bayt al-Hikma (House of Wisdom) in Baghdad.

Scholar Field Contribution
Ibn Sina (Avicenna) Medicine, Philosophy Canon of Medicine — documented 760 drugs; standard text in Europe until 17th century
Al-Biruni History, Geography Tahqiq ma lil-Hind (11th century) — encyclopaedic study of India
Al-Khwarizmi Mathematics Algebra (al-jabr); Algorithm (name derived from his name)
Ibn Rushd (Averroes) Philosophy Commentaries on Aristotle; influenced European scholasticism
Al-Idrisi Geography Accurate world maps for King Roger II of Sicily
Firdausi Literature Shahnama — 50,000-couplet Persian epic; took 30 years to write

🔗 Indian Connection

  • Panchtantra was translated into Arabic as Kalila wa Dimna — spread Indian fables across the Islamic world and into medieval Europe
  • Indian numerals (0–9) reached Europe through Arabic scholars — hence "Arabic numerals"
  • Al-Biruni learned Sanskrit and wrote the most detailed contemporary account of 11th-century India

7. Art and Architecture

  • Arabesque — intricate geometric and vegetal decorative patterns (no figural art in religious contexts due to Islamic law)
  • Calligraphy — elevated to highest art form; Quranic verses as decoration
  • Mosques — characterised by minarets, domes, and large open courtyards
  • Madrasas — Islamic institutions of higher learning combining religious and secular education
  • Akhbar — eyewitness oral and written historical reports; basis of Islamic historiography

Exam Strategy

UPSC Prelims — Focus on:

  • Hijra: 622 CE, Mecca to Medina; starts Hijri calendar
  • Rashidun caliphs: Abu Bakr → Umar → Uthman → Ali
  • Umayyads: Damascus; Abbasids: Baghdad
  • Ibn Sina: Canon of Medicine; Al-Biruni: Tahqiq ma lil-Hind
  • Mongols sacked Baghdad: 1258 CE
  • Jaziya = tax on non-Muslims (Dhimmis)

UPSC Mains (GS1 — Medieval World History):

  • Factors behind rapid Arab expansion post-632 CE
  • Abbasid Golden Age and transmission of knowledge to Europe
  • Significance of the Crusades as cultural contact, not just military conflict
  • Sufism as a parallel tradition within Islam; its role in spreading Islam in India
  • Comparison: Iqta system (Islamic) and Jagir system (Mughal)
