Europeans began exploring new trade routes and lands for several reasons: Europe was experiencing poverty, disease, and conflict in the late Middle Ages. The capture of Constantinople in 1453 blocked the lucrative Silk Road trade route to Asia, making spices and silk expensive. New technologies like the compass, caravel ships, gunpowder, and advances in astronomy allowed Europeans to explore further in search of new trade paths to Asia. Entrepreneurs would convince monarchs to fund expeditions by promising wealth from trade and potential for spreading Christianity and empire.
