An Unknown Ocean

In the 16th century, the Pacific Ocean was an insurmountable abyss. It was a space without precise boundaries, of unknown dimensions, and without routes along which it was possible to travel, in either direction.

Spanish and Portuguese explorers passed on their knowledge of a wide range of people and places, which had not previously been connected. The first circumnavigation of the globe, and subsequent voyages, shaped the new ocean.

In 1513, humankind's history changed forever; as shown in the exhibition The Pacific: Spain's Quest for the South Sea. It was held at the General Archive of the Indies, later traveling to several different countries between 2013 and 2015.

Christopher Columbus' arrival to the Americas, in which he first laid eyes on the New World, was only the beginning. Many people continued to be interested in navigation, and in reaching the mythical Maluku (formerly the Moluccas or Spice) Islands.

One such intrepid explorer and adventurer was Vasco Núñez de Balboa, who stowed away on one of the expeditions around the coasts of the Americas. This is Bartolomé de las Casas' account of it.

Desirous of glory and riches, he sailed around the Isthmus of Panama and the wilderness of Darien. In 1513, guided by indigenous people, he caught sight of the new ocean, naming it the South Sea.

This achievement, as well as the events in which he played a part, are recorded in documents held in the General Archive of the Indies: the conquest and its consequences, the battles, the rivalry between the new settlers, and his sentencing to death in 1519.

This manuscript, which records his exploits and is signed by him, is particularly interesting. In it, he defends the accusations that were made against him, at the time that he sent a wonderful gift to the king of Spain: a very large pearl.

In 1513, the monarch wrote to Pedrarias Dávila, the new governor of the region of the isthmus of Panama, informing him of what Vasco Núñez de Balboa had achieved. In the margin, he wrote: thanks be to God for his discovery of the South Sea.

Exploring the Pacific Ocean

The ocean's vast waters were explored over the course of just a few decades, culminating in the fulfilment of their mission: to cross the ocean, that last bastion of myth and legend.

The Spanish sailed around the coasts of the Americas in search of a passage to the South Sea. The passage was found by Ferdinand Magellan, after whom the strait linking the two oceans was named.

The discovery of a maritime route from Spain to the far-off Maluku (formerly the Moluccas or Spice) Islands prompted new expeditions, which gradually led to the charting of that vast ocean.

One such expedition was led by García Jofre de Loaisa, with Juan Sebastián Elcano as a crew member. These journeys were hard and dangerous. In fact, Juan Sebastián Elcano died during this expedition, having first written his last will and testament.

In 1565, Miguel López de Legazpi commanded the fleet that, having set sail from the Mexican coast, led to the permanent presence of the Spanish in the Philippines. However, the return route to New Spain had not yet been found.

The experienced Andrés de Urdaneta, a friar who had been part of Loaisa's expedition and had acted as a guide to Legazpi, was put in charge of finding the return route, as this document shows.

The successful identification of a return route saw the development of regular journeys between Manila and Acapulco, enabling encounters and exchanges between Asia, the Americas, and Spain.

New Boundaries, New People

Following those expeditions, the Pacific Ocean became a new passage; a bridge between continents.

Manila, the capital of the Philippines, became a trading center, receiving products from across Southeast Asia and sending them on to Spanish America.

Chinese traders and artisans settled in the city and its suburbs. This community played a key role in the development of commercial exchanges with continental ports, from India to Japan.
