- Lucas: So we've talked a lot about Portugal's empire in Asia and Africa, but today I want to look west — to the Amazon. Because for a long time, Portugal's claim to Brazil was really just a strip along the coast, and the interior, especially the Amazon basin, was up for grabs. Luna: Right, the Treaty of Tordesillas gave them the line, but actually controlling that vast jungle was another story. Lucas: Exactly. And the threats came from all sides. The French had their own ambitions in the region — they established a colony called France Équinoxiale, or Equinoctial France, in modern-day Maranhão in the early 1600s. They even built a fort, São Luís, which is today the city of São Luís do Maranhão. Lucas: The Portuguese, under the governorship of Francisco de Sousa, mounted an expedition in 1614 to expel them. It wasn't a huge battle, but it was decisive — the Portuguese forced the French out, and then they founded the city of Belém in 1616 at the mouth of the Amazon River to secure control. Luna: So Belém was basically a strategic fortress, not just a settlement. Lucas: Exactly. Belém became the hub for Portuguese expansion into the Amazon. And from there, they started pushing upriver, establishing forts and missions — often with Jesuit help. But the real challenge wasn't just kicking out the French; it was holding off the Dutch and the Spanish, too. Lucas: The Dutch had taken over Pernambuco in the 1630s, and they were a constant threat along the northern coast. But in the Amazon, the Portuguese had another problem: the Spanish, who claimed the region based on earlier exploration by Vicente Yáñez Pinzón. So Portugal had to rely on a combination of military force, alliances with indigenous peoples, and clever diplomacy. Luna: The diplomatic part is fascinating — how did they settle the borders? Lucas: That's where the Treaty of Madrid of 1750 comes in. It was essentially a redrawing of the map of South America. The Portuguese diplomat Alexandre de Gusmão negotiated it, and he used a principle called 'uti possidetis' — basically, 'you keep what you hold.' So if the Portuguese had actually occupied and controlled a piece of land, they got to keep it, regardless of the old Tordesillas line. Lucas: This was a brilliant move. The Portuguese had been slowly pushing into the interior for over a century — through bandeirantes, missionaries, and settlers. So by 1750, they controlled much more territory than the Spanish realized. Gusmão managed to get that recognized in the treaty. Luna: The bandeirantes — those were the São Paulo explorers, right? They went into the interior looking for slaves and gold. Lucas: Yes. The bandeirantes from São Paulo were incredibly effective. They pushed west, deep into the Amazon basin, and established settlements. They also captured and enslaved many indigenous people, which is a dark part of the story. But from the Portuguese Crown's perspective, they were extending sovereignty. The Crown rewarded them with titles and land grants. Lucas: The Portuguese also used the Jesuits — the Society of Jesus — who set up missions in the Amazon to convert the indigenous populations. The Jesuits often protected the indigenous people from enslavement, which created tension with the colonists and the Crown. But the missions also served as outposts of Portuguese influence. Luna: I can imagine that balancing colonial expansion with the Jesuits' protection of indigenous people was tricky. Lucas: It was, and it came to a head under the Marquis of Pombal in the 1750s. Pombal was the prime minister under King José I, and he had very Enlightenment ideas. He wanted to centralize control, reduce the power of the Church, and integrate indigenous people into Portuguese society. So he expelled the Jesuits in 1759 and implemented the 'Diretório dos Índios' — a policy that aimed to turn indigenous people into Portuguese subjects, speaking Portuguese and adopting Portuguese customs. Luna: That's a big shift from the missionary approach. Lucas: It was. Pombal also strengthened the military presence in the Amazon. He ordered the construction of the Fortress of São José de Macapá, which still stands today. And he created the Company of Grão-Pará and Maranhão to foster trade and settlement. All of this was aimed at securing the Amazon for Portugal, especially against any Spanish incursion from the west. Lucas: By the end of the 18th century, Portugal had effectively claimed the Amazon basin. The borders established by the Treaty of Madrid, later modified by the Treaty of San Ildefonso in 1777, became the basis for modern Brazil's frontiers. It's a remarkable achievement for a small European nation. Luna: You know, it strikes me that this whole story — defending a territory through exploration, diplomacy, and sometimes coercion — is a thread that runs through so much of Portuguese history. Lucas: It really does. And it's a good reminder that if you enjoy these deep dives into Portugal's past and want to keep the show ad-free, listener support makes that possible.

It genuinely helps us keep doing the research and sharing these stories. Luna: Absolutely. Every bit of support goes right back into the show. Now, back to the Amazon — you mentioned the bandeirantes pushing west. Were there any specific expeditions that really made a difference? Lucas: Yes, there were several. One notable figure was Antônio Raposo Tavares, a bandeirante who led a massive expedition from São Paulo all the way to the Amazon in the 1640s. He and his men traveled thousands of miles, enslaved thousands of indigenous people, and opened up routes that would later be used by settlers. His expedition was brutal, but it effectively claimed a huge swath of territory for Portugal. Lucas: There was also the work of the frontier governors, like Francisco de Mello e Castro, who fortified the Amazon river forts and established a network of settlements. The Portuguese Crown even sent soldiers and engineers from Europe to build fortifications. The Fortress of Óbidos, for instance, was built in the 1630s to control the narrows of the Amazon River. Luna: So it wasn't just a matter of planting a flag; they actually built infrastructure. Lucas: Exactly. And the Dutch threat in the Amazon was real. They had taken control of the mouth of the Amazon for a short time in the 1620s, but the Portuguese expelled them in 1623 with a fleet from Belém. Later, the Portuguese also had to deal with the French again in the late 1600s, when they tried to establish a colony in modern-day French Guiana. The Portuguese Crown responded by strengthening the garrison at Macapá. Luna: It seems like the Amazon was a constant chess game. Lucas: It was. And the Portuguese were quite successful at it because they combined force with diplomacy. For instance, they signed treaties with the Spanish Crown in the 18th century that recognized their claims, and they also made alliances with some indigenous groups, like the Tupi and the Tapuia, to help fight their enemies. Lucas: But the most lasting result is that Brazil today is the country it is because the Portuguese Crown was determined to hold onto the Amazon. Without that determination, Brazil might have been fragmented into several smaller colonies. Luna: It's a powerful legacy. And it shows how a small nation's strategic thinking can shape a continent. Lucas: Absolutely. And that's a good place to leave it for today. Next time, we'll look at another corner of the Portuguese empire that often gets overlooked.
