1.9 Non-European Influences

The Ottoman Threat and Exchange

The Ottoman Empire's capture of Constantinople in 1453 ended the Byzantine Empire and sent Greek scholars fleeing to Italy, fueling Renaissance humanism. Ottoman expansion into the Balkans and the Mediterranean threatened European trade routes and Christian states, forcing rulers to view the Ottomans as both a rival and a source of goods and ideas.

Trade Routes and Motivation for Exploration

European access to Asian goods depended on Muslim and Italian intermediaries controlling overland routes. High costs and Ottoman control of eastern Mediterranean trade pushed Portugal and Spain to seek direct sea routes to Asia, bypassing middlemen. This search combined economic motives with a desire to spread Christianity and gain strategic advantage over rivals.

Cultural and Intellectual Borrowing

Europeans absorbed knowledge from Islamic and Byzantine scholars, including preserved Greek and Roman texts, advances in mathematics, astronomy, and navigation (like the astrolabe). This transfer of knowledge helped enable European exploration and enriched Renaissance learning, showing that European advancement relied heavily on non-European contributions.
