Mengapa Bangsa Eropa Harus Pergi Berlayar Mencari Tanah Baru? | Sejarah Pelayaran Eropa

Causes of European Exploration
📌 A primary driver for Western nations to risk voyages across dangerous oceans was the Ottoman Empire's control over land trade routes to Asia, particularly the Silk Road.
💰 The conquest of Constantinople (now Istanbul) by the Ottoman Turks led to increased and unfavorable taxes on European merchants accessing Asian goods like spices.
🗺️ High costs and limited access to Asian markets via the traditional overland route forced European nations, particularly Spain and Portugal, to seek alternative sea routes to Asia.
👑 These exploratory missions were often driven by the 3Gs: Gold, Glory, and Gospel.

The Age of Discovery Pioneers
🧭 Many early European explorers were supported by the prevailing Astronomical Revolution (Copernicus, Galileo), which proved the Earth was round, encouraging long-distance sea travel.
⚔️ Spain and Portugal became leaders in exploration due to their advanced navigation skills and superior naval fleets compared to other European powers.
📜 The Treaty of Tordesillas, mediated by Pope Alexander VI, formally divided the unexplored world, assigning the western part to Spain and the eastern part to Portugal.

Key Expeditions
🚢 Christopher Columbus's first voyage in 1492, sponsored by Ferdinand II and Isabella I of Spain, aimed to find a westward route to Asia, using the ships *Santa Maria* (commanded by him), *Pinta*, and *Niña*.
🏝️ Columbus landed on San Salvador (now the Bahamas) on October 12, 1492, mistaking the inhabitants for "Indians" and noting their possession of gold.
⚓ Vasco da Gama’s expedition, launched in July 1497, followed the African coast, seeking the spice route, with four ships including the São Gabriel (led by Da Gama).
📉 Da Gama successfully reached Calicut, India, on May 20, 1498, but faced poor reception due to the low value of the goods he offered the local ruler (Zamorin).

Consequences and Losses
💀 Vasco da Gama’s return journey was devastating; out of 170 original crew members, only about 50 survived due to disease (like scurvy) and maritime dangers.
⭐ These voyages, driven by critical thinking and a spirit of questioning, fundamentally shifted world history, leading to the era of European navigation and colonialism which benefited European advancement.

Key Points & Insights
➡️ The fall of Constantinople and subsequent Ottoman taxation served as the critical impetus forcing Western Europe to urgently seek maritime routes to Asia.
➡️ Early explorers treated their voyages like startups, needing high "Groot" (growth) to satisfy their powerful investors (monarchs/sponsors).
➡️ Sailors initially feared sailing too far because many still believed the Earth was flat and that their ships might fall off an edge.
➡️ Vasco da Gama's arrival in India in 1498, despite high losses (around 65% fatality rate), established a direct sea link, bypassing the costly Ottoman trade monopolies.
