- Luna: So we've covered treaties and labor systems, but I've been wondering—how did Portugal actually control the Indian Ocean without a massive navy? Lucas: Great question. The answer is a surprisingly simple piece of paper: the cartaz. It was a maritime pass that all ships had to purchase from the Portuguese to sail in the Indian Ocean. Without it, they risked seizure or attack. Lucas: The system started shortly after Vasco da Gama's arrival in 1498. By the early 1500s, the Portuguese had established fortified bases at Goa, Malacca, and Hormuz, and from there they enforced this licensing regime. It was less about having ships everywhere and more about controlling the choke points. Luna: So any ship—Muslim, Hindu, whatever—had to pay up? Lucas: Exactly. The cartaz specified the ship's route, cargo, and crew. You had to declare what you were carrying, pay a fee, and sometimes even carry a Portuguese factor or official on board. If you were caught without one, your ship and goods were confiscated. Lucas: The idea was to monopolize the spice trade, but also to tax all other goods moving across the ocean. It was a brilliant revenue stream for the Estado da Índia, which was always short on cash. Luna: Didn't local rulers resist? I'm thinking of the Zamorin of Calicut. Lucas: Absolutely. The Zamorin was a constant thorn. He fought the Portuguese in a series of naval battles and even allied with the Mamluks and later the Ottomans to challenge their control. But the Portuguese had superior ships and cannons, especially after Afonso de Albuquerque's reforms. Lucas: Some rulers, like the Sultan of Hormuz, submitted and accepted the cartaz system because it was less costly than war. Others, like the Sultan of Gujarat, resisted fiercely. The siege of Diu in 1538 was a major clash where a combined Gujarati-Ottoman force tried to break Portuguese control, but failed. Luna: So the cartaz was enforced by force, but also by diplomacy? Lucas: That's right. Albuquerque and later governors made treaties with local powers that recognized the Portuguese right to issue passes. In return, these rulers got protection from pirates and lower tariffs on their own trade. It was a pragmatic system. Lucas: But it wasn't foolproof. Corruption was rampant—officials sold fake cartazes or accepted bribes to overlook violations. Smuggling thrived, especially by Gujarati merchants who knew the waters well. And as the Mughal Empire grew strong, they didn't bother with passes. Luna: The Mughals just ignored the Portuguese? Lucas: To a degree. The Mughal emperor Akbar made treaties, but they were more about mutual non-aggression. The Portuguese controlled the seas, but the Mughals ruled the land. So trade still happened, but under different terms. Lucas: The real challenge came from European rivals. The Dutch and English arrived in the early 1600s, and they didn't respect the cartaz at all. They armed their ships and fought the Portuguese, and eventually the system crumbled. Luna: Interesting. So the cartaz was effective for about a century, but couldn't handle competition. Lucas: Exactly. It was a remarkable tool for its time—a kind of early modern maritime regulation. It gave Portugal an empire on the cheap, but it also sowed resentment and corruption. By the mid-1600s, the Dutch and English had taken over key routes, and the cartaz became a relic. Luna: We've talked about the Portuguese Inquisition in Goa, and the mita system in the Americas. This seems like another example of empire being run on paper as much as by force. Lucas: Absolutely. The cartaz was bureaucracy as weapon. It's a reminder that colonialism wasn't just about guns and gold—it was about documents, laws, and the power to say who could cross a line on a map. Luna: Speaking of that kind of power, I'm glad this show doesn't run ads. It keeps the focus on the history. Lucas: That's the idea. We deliberately keep this ad-free because we think the story matters more. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. No pressure, but it helps keep us going. Luna: Yeah, and it lets us dive into these niches like the cartaz system without interruption. Lucas: Right. Back to the cartaz—one of the most fascinating aspects is how it reshaped trade networks. Gujarati merchants, who had dominated the Indian Ocean for centuries, saw their influence decline as they had to pay Portuguese fees or risk losing ships. Lucas: Some adapted by trading in areas outside Portuguese control, like the Red Sea or the Persian Gulf. But the spice trade shifted to routes controlled by the Portuguese, who then sold spices at high prices in Europe. Luna: So the cartaz didn't just control ships—it shifted economic power. Lucas: Exactly. It was a tool of economic warfare. By controlling who could carry what, the Portuguese could strangle rival ports and favor their own. It's a precursor to modern trade sanctions in a way. Luna: That's a great way to see it. Thanks, Lucas. Lucas: Thanks, Luna. And for our listeners, if you want to explore more about early colonial systems, we'll have more episodes ahead. Take care.
