Answer:
The Portuguese did not establish their trade network peacefully. They used a combination of diplomacy, military force, and economic coercion to establish their trading posts and forts around the world.
In the early 15th century, the Portuguese began to explore the coast of Africa in search of a sea route to India. They were motivated by the desire to find new sources of gold and spices, and to break the Arab monopoly on trade with the East.
The Portuguese were successful in establishing a trade network that stretched from West Africa to India. They built forts and trading posts along the coast, and they used their military power to protect their interests. They also used economic coercion, such as imposing high tariffs on goods that were not Portuguese, to force local rulers to trade with them.
The Portuguese trade network was a major source of wealth for Portugal. It also helped to spread Portuguese culture and language to other parts of the world. However, it was also a source of conflict and violence. The Portuguese often clashed with local rulers and populations, and their trade network was based on exploitation and inequality.
