Why did the voyages of discovery take place during the 15th and 16th centuries?

The voyages of discovery during the 15th and 16th centuries were driven by a combination of factors, including the desire for new trade routes to access valuable spices and goods in Asia, the quest for wealth and resources, and the spread of Christianity. Advances in navigation technology, such as the compass and improved maps, facilitated longer sea journeys. Additionally, the rise of powerful nation-states and competition among European powers motivated exploration to expand their empires and influence. These factors culminated in significant maritime explorations, leading to the discovery of new lands and the establishment of colonial empires.
