'Iberian Union' is modern day term that refers to the historical political unit that governed all of the Iberian peninsula south of the Pyrenees from 1580-1640. This union was composed of Portugal and Spain, after the Portuguese dynastic crisis and in a personal union of the crowns, along with their respective colonial possessions. To unite Iberia was one of the ambitions of medieval monarchs of the Iberian peninsula. Sancho III of Navarre and Alfonso VII of Castile both took the title ''Imperator Totius Hispaniae'', meaning "Emperor of All Spains"[1] centuries before. The union could have been achieved earlier had Miguel da Paz, Prince of Asturias, become king. He died early in his childhood. The history of Portugal from the dynastic crisis in 1578 to the first Braganza Dynasty monarchs is a period of transition. The Portuguese Empire was near its height at the start of this period and continued to enjoy widespread influence in the world after Vasco da Gama had finally achieved the goal that emerged from the exploratory efforts inaugurated by Henry the Navigator of reaching the east by sailing around Africa in 1497-1498, thereby opening up an oceanic route for the immensely profitable spice trade into Europe that bypassed the Middle East. Throughout the 17th century the increasing predations and surrounding of Portuguese trading posts in the east, by the Dutch, English and French, and their rapidly growing intrusion into the the Atlantic slave trade, undermined Portugal's' near monopoly on the lucrative oceanic spice and slave trades, thereby sending the kingdom into a long decline. To a lesser extent the diversion of wealth from Portugal by the Habsburg regime to help support the Catholic side of the Thirty Years War and in fighting the Dutch, also contributed to the weakening of Portugal's financial position. However it should be noted that Spain's checking of rival powers extended the period of Iberian maritime dominance, albeit under severe challenge, well into the 17th century. These events, and those which occurred at the end of Aviz dynasty and the period of Iberian Union, led Portugal to a state of dependency on its colonies, first India and then Brazil. This shift from India to Brazil was a consequence of the rise of the Dutch and British empires that grew from their trading posts in the east. A similar shift occurred after the independence of Brazil, resulting in Portugal focusing more on its possessions in Africa.
Establishment of the Iberian UnionMain articles: Struggle for the throne of PortugalThe Battle of Alcazarquivir in 1578 saw both the death of the young king Sebastian and the end of the House of Aviz. Sebastian's successor, the Cardinal Henry of Portugal, was 70 years old at the time. Henry's death was followed by a dynastical crisis, with three grandchildren of Manuel I claiming the throne: Catherine, Duchess of Braganza, married to John, 6th Duke of Braganza, António, Prior of Crato and Philip II of Spain. António had been acclaimed King of Portugal by the people of Santarém on July 24, 1580 and then in many cities and towns throughout the country. Some members of the Council of Governors of Portugal, who had supported Philip, escaped to Spain and declared him to be the legal successor of Henry. Then, Philip II marched into Portugal and defeated the troops loyal to the Prior of Crato in the Battle of Alcântara. Philip II was crowned Philip I of Portugal in 1581 (recognized as official king by the Cortes of Tomar) and the Portuguese House of Habsburg (also called the Philippine Dynasty) began. Portugal's status was maintained under the first two kings of the Iberian Union, Philip I and his son Philip II of Portugal and III of Spain. Both monarchs gave excellent positions to Portuguese nobles in the Spanish courts, and Portugal maintained an independent law, currency, and government. It was even proposed to move the Royal capital to Lisbon. However, the joining of the two crowns deprived Portugal of a separate foreign policy, and Spain's enemies became Portugal's. The war with England led to a deterioration of the relations with Portugal's oldest ally (since the Treaty of Windsor in 1386) and the loss of Hormuz, although the English hope in a rebellion against the kings (tried by Elisabeth I) assured the survival of the alliance. War with the Dutch led to invasions of many countries in Asia, including Ceylon (today's Sri Lanka), and commercial interests in Japan, Africa (Mina), and South America. Even though Portuguese were unable to capture the entire island of Ceylon, they were able to keep the coastal regions of Ceylon under their control for a considerable time. Brazil was partially conquered by both France and the Seventeen Provinces. The Dutch intrusion into Brazil was longer lasting and more troublesome to Portugal. The Seventeen Provinces captured a large portion of the Brazilian coast including Bahia, Salvador, Recife, Pernambuco, Paraíba, Rio Grande do Norte, Ceará, and Sergipe, while Dutch privateers sacked Portuguese ships in both the Atlantic and Indian Oceans. The large area of Bahia and its city, Salvador, was recovered quickly by a Portuguese-Spanish military expedition in 1625. The other smaller, less developed areas were recovered in stages and relieved of Dutch piracy in the next two of decades by local resistance and Portuguese expeditions. | :: |
