Life and Death of King Sebastião I
Overview
Sebastião I, the Unexpected King. He came to the power after his brother José I died after only 1,5 years of reign. Unfortunate hunting accident put the new King on throne- one that could not hope to inherit. Despite of that, Sebastião ruled well and steered the fate of Portugal for 18 years. He was a good military commander and military leader, but average administrator and diplomat. Overall, his rule was successful, even if a bit boring.
By the time Sebastião came to power in 1610, Portugal was already an Empire. Her territories dwarfed the Roman Empire- and the territories were everywhere. In Europe, in Africa, in Asia and in America. Her navy was without a match (well, unless you match it with Denmark, but why should you?), her armies one of the biggest and most importantly- Portugal dominates the trade from Asia to Europe and from South America to Europe. The wealth flowing to Lisboa makes the Portuguese King richest in the world. Meaning- Sebastião had everything he needed for success- ships, men and money.
Trade Wars
When ruled by Sebastião, Portuguese did not expand as aggressively anymore. Partly because they already were almost everywhere they needed to be. What Sebastião tried to achieve was to strengthen Portuguese influence over either trade nodes or to further the influence in Europe.
Sebastião did inherit a war that was originally fought against Yemen, but then Ottomans and Mali and Persia joined in and the conflict grew a bit more then Portugal had bargained for. Lasting from 1610-1612, Portugal managed to gain two provinces, including Island of Socotra. More power in Aden is always good.
In 1617, Sebastião did declare war to Brunei, owner of the biggest island in Spice Islands, the Island of Borneo. Also, to Brunei, the nation with the second biggest fleet patrolling the Malacca node (you don’t have to guess who has the biggest, right?). When the war ended in 1619, Brunei had only half of Borneo and much smaller fleet.

Also, from 1623-1627, Portuguese fought over Malacca and Sumatra Island with Ayutthaya. Result- Malacca and Aceh, two out of three important nodes in Spice Islands, were safely Portuguese.
As we can see, total three wars with only one goal- expand Portuguese influence over key trade nodes. Both Aden and Malacca were more firmly under Portuguese rule than ever, with more and more gold flowing through the nodes and ending up in Lisboa.
Italian Adventures
During the reign of Sebastião, Portugal finished integration of Tuscany to Portuguese land. Tuscany is a Portuguese vassal from 1580. In 1606, King João IV, father of Sebastião, started integration of Tuscany. It was going well, apart for a small war. From 1611-1615, Sebastião fought with Saxony in a war started by Great Britain over Salzburg, fought mostly in Central Italy with Mantua. Before Portuguese did react, Mantuans had put both Tuscany and Pisa under siege and were threatening Portuguese influence in the area. When Portuguese did arrive, they defeated Mantua and forced them to give up Siena as independent nation (and soon, a Portuguese vassal). In 1616, Tuscany was officially integrated to Portugal and first provinces in the Italy were gained.
When João IV integrated Aragon, he gained the Island of Malta- and another entry point into Italy. From there, Sebastião started another push into Italy, fighting Sicily and gaining the province of Palermo in a war lasting 1619-1622. By the time Sebastião died, Portugal had four provinces in Italy- Pisa, Tuscany, Palermo and Siena as a vassal. Plus, Sicily as an ally and potential vassal.

World War I
The highest achievement of Sebastião is the Spanish coalition war. It started when Portuguese declared war on Ayutthaya in 1623. Both of Portuguese Indian armies were busy with that war and half of Portuguese European armies were in Sicily. So, Spain thought it would be a good time to strike and in 1624, they declared war on Portugal. Meaning, Portuguese and their allies Great Britain and Siena had to fight the following nations:
From Europe: Spain and Denmark (ally of Spain, not part of the coalition)
From Middle East: Ottoman Empire and Yemen
From India: Bahmanis, Golkonda,
From America: Aztecs
From Spice Islands: Majapahit, Aceh, Pattani
The war was fought in Europe, in Asia, in India, in America and in Middle East. It was the first war known to mankind to engulf all of the globe and thus, it became known as the first World War and a biggest challenge Portugal has faced to date. Of course, Portugal herself was also bigger than ever.
Battle of Vizcaya, fought in February 1625, is the bloodiest battle Portuguese had fought to date- and also a testament to power of the Portuguese. Spanish managed to gather an army of 24 000 soldiers and it was almost all they had, and all of their forces in Europe. Against them were 42 000 Portuguese. Plus, about 20 000 in Indian Ocean area, 10 000 still in Italy, 10 000 or so sieging other Spanish provinces and 10 000 or so in America- meaning about 100 000 soldiers all over the world. And of course, the Spanish armies were defeated, making Portugal the only power left in Iberia.
Battle of Vizcaya
Losses in Arabian Peninsula, especially the loss of Aden to Yemen were more than compensated by victories in India. By the end of 1625, the subcontinent was cleared of enemy troops. In America, Portuguese were doing their usual Aztec-slaughter. Overall, it could be said that Sebastião fought the world- and won. Perhaps most remarkable achievement is the conquest of Iberia- every single province under Portuguese rule. As a victor Portugal signed peace in 1627, gaining three provinces- one in India, one in America and one in Iberia. War with global extent and global gains.
Occupation of Iberia
Also in 1627, the war with Malacca came to close, with Portuguese gaining both Malacca and Aceh, important centres of trade from Malacca node, plus another province in Sumatra. Total 6 provinces from two wars- not bad.
Portuguese Navy
By 1619, Portugal had around 150 ships. Mostly frigates, patrolling the seas of the world, also around 30 heavy ships and 20 transports. Making it the biggest navy in the world- and too small for Portuguese needs. After all, Portugal needs a proper heavy fleet to guard home, smaller heavy fleet to dominate Indian Ocean, enough transports to sail the troops around and a lot of light ships to protect a total of 15 trade nodes Portugal is active in.
Sebastião adopted naval ideas in 1612. By 1619, Portugal was ready to adopt the grand navy idea, increasing Portuguese ship limits further by 50 ships, to around 230 ships. In a few years, the limit was filled. By the time Sebastião died, the Portuguese had 41 galleons, 40 merchantmen and 154 early frigates. Three next naval nations are Denmark, Great Britain and France, all with little over 90 ships.

Colonization
During the reign of Sebastião, Portugal continued their colonization efforts all over the world. Portuguese Peru and Mesoamerica were already colonized almost as much as possible.All was not great though- unfortunately, it seems like Spain has won the race for South American colonization. Most of the continent was Spanish, though Portugal held a powerful base in Brazil and owned land from North Peru to Mexico. In his final years, Sebastião also ordered Portuguese to move north, to West Coast of North America. First colonists were sent, but the King died before they arrived.
Spain is the dominant power in South America
Also, Portuguese continued their expansion of Spice Islands. Perhaps the biggest achievement was Island of Sulawesi. After taking Makassar from Brunei, Portuguese troops pacified rest of the island and by the time Sebastião died, all of the island was under Portuguese rule. In addition, Portuguese colonists settled other small islands in the area.
While Portugal is the only European power in Far East
As for Africa- so far, Portuguese had treated Africa like a stepping stone to Asia. With colonies only in strategic areas around Mauretania, Ivory Coast, Kongo and Cape, plus holdings taken from Swahili in the east coast, they served as strings of naval bases where Portuguese settlers could resupply their ships. Sebastião started to change that- under his rule, Portuguese started filling out the gaps on the map. During his reign, Portuguese colonies were settled from Rio de Oro to Cameroon.
Expanding in Africa
Conclusion
The reign of Sebastião was stable. Portugal did not attempt new gains, but instead consolidated the existing ones. A good King and more than capable general, he expanded Portuguese influence all over the world.
