AP World History: Modern — Unit 1 | Reading time: ~20 min

1. What is Dar al-Islam?

Dar al-Islam literally means "House of Islam" in Arabic. It describes lands where:

• Muslims can practice their faith freely
• Islamic law (sharia) influences governance
• A Muslim ruler or significant Muslim community exists

By 1200, Dar al-Islam stretched from Spain to Southeast Asia. Despite political fragmentation, Muslims shared religion, trade networks, and scholarly traditions.

2. The Abbasid Caliphate in Decline

The Abbasid Caliphate (750–1258) once ruled a vast empire from Baghdad. By 1200, it had weakened significantly.

2.1 Causes of Decline

• Political fragmentation: Regional leaders (emirs, sultans) became effectively independent.
• Military reliance on Mamluks: Turkish slave-soldiers gained power and sometimes controlled caliphs.
• Economic strain: Reduced tax revenue as provinces broke away.
• Crusader and Mongol threats: External invasions drained resources.

2.2 Fall of Baghdad (1258)

The Mongol army under Hulagu Khan sacked Baghdad, killing the last Abbasid caliph and destroying the city. This ended the "classical" caliphate but not Islamic civilization.

• House of Wisdom libraries destroyed—massive loss of manuscripts.
• However, other Islamic centers (Cairo, Damascus, Delhi, Timbuktu) preserved and continued scholarship.
• Some Mongol successor states (Ilkhanate) later converted to Islam.

3. Successor States and New Islamic Powers

3.1 The Delhi Sultanate (1206–1526)

A series of Turkic Muslim dynasties that ruled northern India from Delhi.

• Brought Islam to South Asia; built mosques, introduced Persian court culture.
• Mixed policies toward Hindus: jizya (tax on non-Muslims) enforced, but Hindu elites often retained local power.
• Survived Mongol invasions that devastated other Islamic regions.
• Spread Indo-Islamic architecture (Qutb Minar) and promoted Sufi saints.

3.2 The Mali Empire (c. 1235–1600)

A powerful West African state that controlled Trans-Saharan trade routes.

• Mansa Musa (r. 1312–1337): famous for his 1324 pilgrimage to Mecca, distributing so much gold he caused inflation in Egypt.
• Timbuktu became a major center of Islamic learning and trade.
• Islam spread through merchant contacts and royal patronage, blending with local traditions.

3.3 Turkic Dynasties in the Middle East and Central Asia

• Seljuk Turks: Controlled much of Persia and Anatolia; defended against Crusaders.
• Mamluks of Egypt: Slave-soldier dynasty that defeated both Crusaders and Mongols; ruled Egypt and Syria (1250–1517).
• Ilkhanate: Mongol successor state in Persia; rulers converted to Islam by 1295.

4. How Islam Spread (1200–1450)

Islam continued expanding through three main mechanisms:

4.1 Syncretism

Syncretism = blending of different religious or cultural traditions. As Islam spread, it often mixed with local practices:

• In India: Sufi shrines became pilgrimage sites for both Muslims and Hindus.
• In West Africa: Islam incorporated local ancestor veneration and traditions.
• In Southeast Asia: Hindu-Buddhist elements blended with Islamic practices.

5. Islamic Scholarship and Cultural Achievements

Despite political fragmentation, the Islamic world remained a center of learning.

5.1 Preservation and Translation

• Muslim scholars preserved Greek philosophy (Aristotle, Plato) and translated texts into Arabic.
• These works later reached Europe via Spain and influenced the Renaissance.

5.2 Advances in Science and Math

5.3 Centers of Learning

• Cairo: Al-Azhar University (founded 970, still operating).
• Timbuktu: Sankoré University and thousands of manuscripts.
• Córdoba (Spain): Libraries with hundreds of thousands of books.

6. Trade Networks in Dar al-Islam

Muslim merchants dominated major trade routes:

6.1 Trans-Saharan Trade

• Gold and salt were the main commodities.
• Camel caravans crossed the Sahara; oasis cities became trading hubs.
• Islam spread along these routes to West African kings and merchants.

6.2 Indian Ocean Trade

• Muslims controlled key ports (Hormuz, Aden, Malacca).
• Monsoon winds enabled seasonal sailing; dhows carried spices, textiles, ivory.
• Connected East Africa, Arabia, India, and Southeast Asia.

6.3 Silk Road

• Overland routes linking China to the Mediterranean.
• Pax Mongolica boosted trade; caravanserais (roadside inns) served travelers.
• Ideas, technologies, and diseases traveled these routes.
