8.1 Maritime trade routes

Maritime trade routes were the lifeblood of ancient Mediterranean civilizations. These sea lanes connected diverse cultures, facilitating the exchange of goods, ideas, and technologies. From the Minoans to the Romans, seafaring peoples built vast networks that shaped the region's economic and cultural landscape.

The development of maritime trade was driven by advances in shipbuilding and navigation. As vessels grew larger and more seaworthy, traders ventured further, establishing new routes and colonies. This expansion led to the growth of coastal cities, specialization in production, and the spread of knowledge across the Mediterranean basin.

Origins of maritime trade

• Maritime trade in the ancient Mediterranean world emerged as a result of the region's unique geography, with numerous islands, peninsulas, and coastal areas that facilitated seafaring and commerce
• The development of maritime trade was closely linked to the rise of early civilizations in the region, such as the Minoans, Phoenicians, and Greeks, who relied on the sea for transportation, communication, and economic growth
