Trade routes are paths or networks used for the exchange of goods and services between different regions or countries. These routes can be over land, such as the famous Silk Road, or over water, like the Mediterranean Sea trade routes. They facilitate the movement of products, ideas, and cultures, helping economies to grow and connect. Historically, trade routes have played a crucial role in the development of civilizations. They allowed for the transport of valuable items, such as spices, textiles, and precious metals, which were sought after in various markets. The establishment of these routes often led to the rise of cities and the spread of innovations.
