Why the Age of Exploration started for many European countries in the late 1400s?

The Age of Exploration began in the late 1400s primarily due to a combination of economic, political, and technological factors. European nations sought new trade routes to access valuable spices and goods from Asia, especially after the fall of Constantinople in 1453 disrupted traditional trade paths. Advances in navigation technology, such as the compass and improved ship designs, enabled longer sea voyages. Additionally, the desire for territorial expansion and the spread of Christianity motivated countries like Spain and Portugal to explore uncharted territories.
