Answer:
Through different methods.
Explanation:
1. Portugal's location helped them a lot, they had easy access to the Mediterranean. Their fishermen gave a lot of information on the behaviors of the Atlantic, which in turn gave the Portuguese essential knowledge on how to train their sailors, how to perform their deep sea exploration, and things to document about their history.
2. Their ships. Each of the ships they sailed gave them a better understanding of the conditions required for safe travel across water.
3. Last but not least, religion. Jewish people driven out of Spain took refuge in Portugal and spread their beliefs, which received a small degree of persecution, yet still managed to root its place in Portugal, and serve as its advantage in trading with a wider range of countries.
Humanism is a big role in this. Humanism is the idea of thinking more about the individual (The things people felt and created were just as important as faith and religion)
Since philosophers were now thinking with humanism influencing them, they thought more about the individual person themselves and their role in society. Unlike earlier thinkers who thought about people as a whole and the Church's role in society. People began to come up with the ideas that the Church is not the answer to everything.
The transatlantic slave trade was really a triangle. Here's a map to show the approximate routes. The trade was brought about to benefit the economy of Caribbean nations and Europe. The slaves were forced into awful conditions; cramped boats and harsh climates with which to toil away picking cotton or whatnot.
The antislavery movement raised and grew because people kept finding reasons for why slavery is bad. This eventually led to conflict between people against slavery and people for slavery. Another reason why the antislavery movement raised and grew was because slavery has become less useful overtime, as we have machines.
