João da Gama

João da Gama is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand João da Gama rather than just read about it. In short: João da Gama (c. 1540 – after 1591) was a Portuguese explorer and colonial administrator in the Far East in the last quarter of the 16th century. He was the grandson of Vasco da Gama.

Key takeaways

  • João da Gama belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect João da Gama to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of João da Gama from memory before moving on to harder problems.

Reference excerpt

João da Gama (c. 1540 – after 1591) was a Portuguese explorer and colonial administrator in the Far East in the last quarter of the 16th century. He was the grandson of Vasco da Gama. João da Gama sailed from Macau to northeast and rounded Japan by north. He crossed the Pacific Ocean at the northernmost latitudes taken until then by Europeans. Forced by the circumstances of his voyage, he became also a circumnavigator (one of the first to do it eastwards). The lands northeast of Japan which João da Gama discovered were the target of legend and speculation in the centuries that followed, inspiring its search by European powers.

Early years and voyages to the East Not much is known of his childhood and youth, though is believed that he was born around 1540. His parents were Guiomar de Vilhena, Countess of Vidigueira and Francisco da Gama, 2nd Count of Vidigueira, son of the explorer Vasco da Gama, the discoverer of the sea route to the East. He was married with Joana de Menezes and had one son, Vasco da Gama, who later became captain in Chaul. João da Gama became the captain of Malacca between 1578 and 1582. He received cordially the Portuguese representative who brought the news of the coronation of Philip II of Spain as king of Portugal, but only recognized the new order later, after indication of the Viceroy of India. He had numerous political conflicts within his mandate, caused by alleged personal irregularities that had brought him into political confrontation with the administrative bodiesof the city, which led to a Judicial process. He was accused of harming the interests of Malacca and called to Lisbon to answer for his actions and expose his defense. He returned to the East with the aim of fulfilling the nanban trade (the "voyage of Japan"), between Macau (China) and Nagasaki (Japan), a trade route monopolized by Portugal. Gama was married to the daughter of D. João de Meneses Baroche, Captain of Cochin. He left his wife at his residence in Cochin and headed to Macau in 1588, accompanied by his brother Miguel da Gama. In that year the annual voyage had not yet been carried due to the sudden death of the captain of Macau, Jerónimo de Sousa. Following the trade agreement between the Portuguese-Jew New Christian Bartolomeu Landeiro and the city of Macau, Jerónimo de Sousa was also preparing to send a ship to the Philippines. In parallel to this, was then issued the anti-Christian edict in Japan. João da Gama, hoping to get a higher profit and new possibilities, and against all prohibitions, decided for an expedition to New Spain at his own expense and at his own risk. Da Gama was well-regarded in Macau, as can be seen from the letter that the Macau City Council wrote to the king on 30 June 1588, in which praises da Gama, then captain of Macau and Japan. They also asked the king that he be granted for life with this captaincy. The Câmara of Macau also mentions the subject of a recent Spanish (Castilian) travel to Macau, and the reasons why should be prohibited, among other subjects. Gama and the Council of Macau also argued that the profits of the voyage could sustain churches, a Misericordia, and two hospitals, being a leper one of them. Da Gama took possession of a carrack of 600 tons that instead of going from Macau to India, went to Mexico, where they could accomplish much more lucrative deals, which were coveted by residents of Macau. Years later, members of the Macau City Council would publicly condemn and criticize da Gama and his voyage.

Crossing of the Pacific

The decision of D. João da Gama, a risk taker, was taken with the knowledge that it was an illegal enterprise, since it was well known the prohibition of trade between the world areas of Portugal and Castile (later Spain) by the Treaties of Tordesillas and Zaragoza, ban reinforced by the letters personally written by Philip II to the Viceroys of New Spain and India, and also directly to the administrative bodies of Macau and the Philippines in 1589 and 1590s, leading to the expulsion of the Spanish from Macau in 1592. The unusual and exceptional decision to make the journey was due to the expectation that the initiative might be regarded with tolerance, as happened to some Spanish precedents to Macau, but on the other hand, seems it had been taken in desperate position because da Gama was possibly aware that if he returned to Goa, he would possibly be arrested due to charges of having committed serious irregularities. This reality is reflected in the letter that the king Phillip II (I of Portugal) sent to the Viceroy on February 6, 1589, which ordered him "that the noble (João da Gama) that came from China, should be arrest in irons and taken to the Kingdom aboard this Armada", as was also appointed before, in 1587, by the Crown. João da Gama, however, seemed unaware of this reality in 1588, since he sent from Macau, on November 20 of the same year, a letter to the king informing him of his intention to go to Spain via Mexico, with an alleged justification of give in person to the king part of his mission to China, and show how easy it seemed to be undertaken its conquest (in fact the Portuguese in Macau were against such project). Two days earlier, on November 18, Domingos Segurado, in Macau, also wrote to the king to inform the wreck of a Spanish ship from New Spain in Macau, and the shipment of its crew on da Gama's ship, owner of the voyage to Japan, which, once in Macau, accepted the order of the Viceroy of India to transport that crew to Mexico, being himself in the office of Captain of Macau during Gama's absence, even suggesting his own appointment to that office, or as a reward for his services, the provision of two voyages from China to New Spain.

Worked examples

Example 1 — a first encounter with João da Gama

Start with the simplest possible case. Write down what João da Gama claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to João da Gama before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about João da Gama ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of João da Gama

In research
João da Gama appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses João da Gama in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
João da Gama is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1540s births, 16th-century Portuguese explorers, Circumnavigators of the globe, so understanding it makes those chapters shorter.
In everyday life
Look for João da Gama outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
