Why did Western europesn countries in the 15th century feel they needed to develop new trade routes?

In the 15th century, western European countries sought to develop new trade routes primarily to access valuable goods such as spices, silk, and precious metals, which were dominated by Ottoman and Arab intermediaries. The desire for direct trade routes to Asia was fueled by the potential for immense profits and the growing demand for these exotic commodities. Additionally, the fall of Constantinople in 1453 disrupted traditional trade links, prompting European nations to explore alternative maritime pathways. This period of exploration ultimately led to the Age of Discovery, reshaping global trade dynamics and European economies.
