what gave portugal an advantage in the slave trade?

Portugal had several advantages in the slave trade that contributed to their dominance during that time. Here are a few factors that gave Portugal an edge:

1. Geographic Location: Portugal's strategic location along the western coast of Africa gave it direct access to the African continent. This proximity allowed Portuguese traders to establish close relationships with various African kingdoms and facilitated the transportation of slaves to the major trading ports.

2. Navigational Expertise: Portugal was at the forefront of advancements in navigation technology during the Age of Discovery. Their navigators, like Vasco da Gama and Bartolomeu Dias, developed effective sea routes and mastered techniques such as using trade winds and ocean currents. Their expertise in navigation enabled Portuguese ships to reach Africa and navigate the treacherous routes back to Europe more efficiently, facilitating the transportation of slaves.

3. Established Trade Networks: Portugal had already established trade networks along the African coast before the start of the slave trade. They had a significant presence in trading goods such as gold, spices, and other commodities. These pre-existing networks allowed the Portuguese to easily integrate the slave trade into their existing economic activities.

4. Naval Superiority: Portugal had a formidable navy during this period, equipped with advanced ships such as caravels and galleons. Their naval superiority helped protect their trading outposts and maintain control over the regions where they operated. This ensured the safety and efficiency of Portuguese vessels engaged in the slave trade.

5. Treaty of Tordesillas: The Treaty of Tordesillas, signed in 1494 between Portugal and Spain, divided the newly discovered territories overseas between the two countries. This agreement granted Portugal a considerable portion of Africa and Brazil, giving them a legal claim to those territories and consolidating their power in the slave trade.

These advantages, combined with the ruthless pursuit of profit and the development of an efficient infrastructure, allowed Portugal to establish a dominant position in the early years of the transatlantic slave trade. It's important to note that the slave trade was a deeply immoral and tragic chapter in history, marked by immense human suffering and exploitation.
