As Europe sets off to expand across the oceans, the first contestant was Portugal. Check out a map(s) below. They are super far away from any trade route. Not isolated, but definitely distant from the wealth of the Indian Ocean and access to those port-cities. So, it makes sense that they would lead the way in seeking out new trade routes and peoples to convert to Catholicism. Portugal has a decent head start as well. King John the Good (Henry the Navigator's dad) first took territory in Africa (Ceuta) in 1415. Columbus doesn't bump into the new world for another 77 years. That’s a massive lead in terms of exploration for Portugal. Everyone else took their cues from them in the sea route to Asia. Having said that… Portugal’s empire will not be the largest (Britain) or the longest lasting (Ottomans). But they do have have their own 'crown jewel': Brazil, picking that up with the Treaty of treaty of Tordesillas. But otherwise, they are pretty much just a Trading Post Empire without significant land holdings outside of Brazil. So, when studying the Portuguese; remember them for their explorers; Vasco da Gama, Pedro Álvares Cabral (bumps into Brazil), Ferdinand Magellan, and Bartolomeu Dias, just to name a few. But overall, the are credited as being the first Europeans to reach a lot of places by sea…
