Spread of Islam and its Impact

Islam was able to spread effectively because it adapted to local forms and cultures.

During this time, the Muslims made significant intellectual innovations and transfers.

Greek Classics: Muslims in Spain translated Greek classics (e.g., Plato, Aristotle) into Arabic, preserving them for later rediscovery by Europeans during the Renaissance.
Indian Mathematics: Muslims transferred Indian mathematics to Europeans.
Papermaking: Muslims adopted and adapted papermaking from China, which later played a role in the spread of European ideas via the printing press.

These religions had a deep influence on state building in South and Southeast Asia.

Delhi Sultanate:
- An Islamic state in the north of the Indian subcontinent.
- Majority of people were Hindus.
- Some Hindus converted, often for social mobility from lower to upper castes.
- Those who did not convert had to pay a tax called the $jizya$ .
- The Delhi Sultanate never maintained an efficient bureaucracy, hindering its ability to consolidate power.
Vijayanagara Empire:
- A Hindu kingdom established in the south.
- Founded by two brothers who had converted to Islam while serving the Delhi Sultanate but later reverted to Hinduism and established a rival empire.
