The years 1768 to 1779 may be described as an era of union (in which organizations become increasingly homogenous with unified purpose; economies and efficiencies develop in art, craft, industry, and infrastructure).

Northeast Asia (1768–1779 CE)

Russian Maritime Exploration and Ecological Impact

Between 1768 and 1779, Russian maritime and fur-trading activities in Northeast Asia intensified significantly, driven by ongoing exploration and commercial incentives. The fur trade continued to flourish, primarily targeting valuable sea otters, fur seals, and fox pelts from the Aleutian Islands and surrounding areas, increasingly impacting local ecosystems and indigenous populations.

During these decades, ships routinely stopped at the Commander Islands, primarily to hunt Steller's sea cows, a large sirenian mammal discovered by the German naturalist Georg Wilhelm Steller in 1741 during Vitus Bering's expedition. Initially numbering fewer than fifteen hundred at their discovery, these creatures provided meat, skins for boats, and valuable subcutaneous fat for cooking and lighting. Intensive hunting by sailors, seal hunters, and traders quickly drove the species to extinction by 1768, less than three decades after their discovery.

In addition to the ecological consequences, this period saw increased European maritime exploration of the region. Captain James Cook's third expedition, aimed at discovering a navigable Northwest Passage, significantly influenced European knowledge about Northeast Asia. After Cook's death in the Hawaiian Islands, command passed to Charles Clerke, who continued exploring the northern Pacific coast and proceeded to the Siberian Pacific coast. Clerke, already weakened by illness, died of tuberculosis on August 22, 1779, en route to Kamchatka. He was buried in Kamchatka on August 29, and his second-in-command, John Gore, assumed leadership, eventually guiding the expedition back to Britain.

This era underscores the profound environmental impact of intensified Russian commercial activities and highlights the significant geographical knowledge gained through European exploratory missions.

Kerguelen Islands appeared as the "Ile de Nachtegal" on Philippe Buache's map from 1754 before the island is officially discovered in 1772.

The Buache map has the title Carte des Terres Australes comprises entre le Tropique du Capricorne et le Pôle Antarctique où se voyent les nouvelles découvertes faites en 1739 au Sud du Cap de Bonne Esperance ('Map of the Southern Lands contained between the Tropic of Capricorn and the Antarctic Pole, where the new discoveries made in 1739 to the south of the Cape of Good Hope may be seen').

It is possible this early name was after Tasman's ship "De Zeeuwsche Nachtegaal."

On the Buache map, "Ile de Nachtegal" is located at 43°S, 72°E, about 6 degrees north and 2 degrees east of the accepted location of Grande Terre.

The islands are officially discovered by the French navigator Yves-Joseph de Kerguelen-Trémarec on February 15, 1772.

The next day Charles de Boisguehenneuc lands and claimed the island for the French crown.

Yves de Kerguelen organizes a second expedition in 1773 and arrives at the "baie de l'Oiseau" by December of the same year.

On  January 6, 1774 he commands his lieutenant, Henri Pascal de Rochegude, to leave a message notifying any passers-by of the two passages and of the French claim to the islands.

Hereafter, a number of expeditions briefly visit the islands, including that of Captain James Cook in December 1776 during his third voyage, who verifies and confirms the passage of de Kerguelen by discovering and annotating the message left by the French navigator.

Soon after their discovery, the archipelago will be regularly visited by whalers and sealers (mostly British, American and Norwegian) who will hunt the resident populations of whales and seals to the point of near extinction

Vietnam is under the nominal rule of the officially revered, but politically ignored Lê Dynasty during the eighteenth century.

Real power is in the hands of two warring feudal families, the Trịnh Lords of the north, who control and rule from the imperial court in Hanoi, and ...

...the Nguyen Lords in the south, who rule from their capital, Huế.

Both sides fight each other for control of the nation, while claiming to be loyal to the king.

Life for the peasant farmers is difficult.

Ownership of land has become more concentrated in the hands of a few landlords as time has passed.

The Mandarin bureaucracy is oppressive and often corrupt; at one point, royally sanctioned degrees are put up for sale for whoever is wealthy enough to purchase them.

In contrast to the people, the ruling lords live lavish lifestyles in huge palaces.

The decades-long war between the Trịnh and the Nguyen had ended in 1673, and life for the northern peasants is fairly peaceful.

However, the Nguyen Lords have engaged in a regular series of wars with the weak Khmer Empire, and later, the relatively strong state of Siam.

While the Nguyen usually win, and despite the fact that the new lands they conquer offer new opportunities for the landless poor, the frequent wars take a toll on their popularity.

Taksin, the new king of Siam, launches a war in 1769 to regain control of Cambodia.

The war generally goes against the Nguyen and they are forced to abandon some of the newly conquered lands.

This failure, coupled with heavy taxes and corruption at the local level, causes three brothers from the village of Tay Son to begin a revolt against Lord Nguyen Phúc Thuần.

The Tay Son brothers style themselves as champions of the people.

Over the next year, the revolt gains traction and they win some battles against the Nguyen army units sent to crush their rebellion.

The Tay Son have a great deal of popular support, not only from the poor farmers, but from some of the indigenous highland tribes.

The leader of the three brothers, Nguyen Huệ, is also a very skilled military leader.

Nguyễn Huệ’s stated goal is to end the people's oppression, reunite the country, and restore the power of the Lê emperor in Hanoi.

The Tây Son also promise to remove corrupt officials and redistribute land.

In 1773 the Tay Son capture the port of Qui Nhon, where the merchants, who have suffered under restrictive laws put in place by the Nguyen, give the uprising financial support.

The Nguyen, at last recognizing the serious scale of the revolt, make peace with the Siamese, giving up some land they had conquered in previous decades.

However, their problems are compounded when Trịnh Sam chooses to end the one hundred-year peace and exploit the turmoil in the south by sending his army to attack Phú Xuân (modern day Huế), the Nguyen capital.

The Trịnh army captures the city, forcing the Nguyen to flee to Gia Định (later called Saigon).

The Trịnh army continues to head south and the Tay Son army continues its conquest of other southern cities.

The Nguyen are unpopular at this time, and the forces against them are too powerful.

The Tay Son army captures Gia Định, the last Nguyen stronghold, in 1776, and massacres the town's Han Chinese population.

The entire Nguyen family is killed at the end of the siege, except for one nephew, Nguyen Ánh, who manages to escape to Siam.

While they say they want to restore power to the Lê, one of the brothers, Nguyen Nhạc, proclaims himself Emperor in 1778.

A conflict with the Trịnh is thus unavoidable.
