The Távora Affair: A Noble Family Destroyed (1758–1759)

Following the attempted assassination of King José I on September 3, 1758, Prime Minister Sebastião José de Carvalho e Melo unleashed a ruthless crackdown on Portugal’s highest-ranking noble families. In the weeks after the attack, Marchioness Leonor of Távora, her husband, Francisco Assis, Count of Alvor, and all of their sons, daughters, and grandchildren were imprisoned.

The Unraveling of a Conspiracy

By December 1758, Carvalho de Melo had constructed a theory of conspiracy—what he saw as a noble-led plot to murder the king and install the Duke of Aveiro as ruler of Portugal. Under his orders, the following figures were arrested:

Duke of Aveiro, the supposed beneficiary of the coup
Marquis of Alorna, son-in-law of the Távoras
Count of Atouguia, another Távora relative
Teresa Leonor de Távora, the king’s mistress, whose affair with José I was now used against the family
Gabriel Malagrida, a Jesuit priest and the Marchioness’s confessor, who had recently returned from exile

They were all accused of high treason and attempted regicide.

The Evidence and Trial

The case against the Távoras was based on three key pieces of evidence:

The confessions of the two executed assassins, obtained under torture
A pistol allegedly belonging to the Duke of Aveiro, identified as the murder weapon
The claim that only the Távoras could have known the King’s location, since he was returning from a clandestine meeting with Teresa de Távora

The trial was highly irregular, marked by forced confessions, secretive proceedings, and predetermined verdicts. The nobility and Jesuits, traditional enemies of Carvalho de Melo, were now facing their downfall.

The Fate of the Jesuits and Malagrida

The Jesuits, long regarded as a powerful and meddlesome force in Portuguese politics, were also implicated in the alleged plot. As a result:

Gabriel Malagrida was declared guilty of high treason
However, as a priest, he could not be executed without the approval of the Inquisition
Instead, he was imprisoned beneath the Tower of Belém, alongside other Jesuit leaders

The entire Jesuit Order was expelled from Portugal, and non-Portuguese members of the Society were detained or exiled.

A Turning Point in Portuguese History

With the nobility crushed and the Jesuits removed, Sebastião de Melo’s power was now absolute. The Távora Affair was not just an act of retribution—it was a political purge that permanently weakened the aristocracy, severed Portugal’s ties with the Jesuits, and solidified Carvalho de Melo’s grip on the kingdom.

But the worst was yet to come. In January 1759, the final reckoning for the Távora family would unfold in an act of brutal spectacle orchestrated by Carvalho de Melo to forever break the power of Portugal’s nobility.

The Qianlong Emperor moves the remaining Dzungar people to other places in China.

He orders the generals to kill all the men in Barkol or Suzhou, and divides their wives and children among the Qing soldiers.

In his account of the war, Qing scholar Wei Yuan, writes that about forty percent of the Dzungar households were killed by smallpox, twenty percent fled to Russia or the Kazakh Khanate, and thirty percent were killed by the army, leaving no yurts in an area for several thousand li, except those of the surrendered.

Qing Bannermen and Mongol cavalry made up the initial expeditionary army.

As the campaigns progressed, tens of thousands of Green Standard infantrymen were also brought in.

The men, women and children of the Dzungars were all slaughtered by Manchu soldiers according to Russian accounts.

The Dzungars had conquered and subjugated the Uyghurs during the Dzungar conquest of Altishahr, after being invited by the Afaqi Khoja to invade.

Heavy taxes had been imposed upon the Uyghurs by the Dzungars, with women and refreshments provided by the Uyghurs to the tax collectors.

Periodically, Uyghur women were gang raped by the tax collectors when the amount of tax was not satisfactory.

Anti-Dzungar Uyghur rebels from the Turfan and Hami oases submitted to Qing rule as vassals and requested Qing help for overthrowing Dzungar rule.

Uyghur leaders like Emin Khoja were granted titles within the Qing nobility, and these Uyghurs helped supply the Qing military forces during the anti-Dzungar campaign.

The Qing employ Khoja Emin in its campaign against the Dzungars and use him as an intermediary with Muslims from the Tarim Basin, to inform them that the Qing only seek to kill Oirats (Dzungars), and that they will leave the Muslims alone.

It will not be until generations later that the population of Dzungaria begins to rebound.

Daniel Boone had returned home from the…

Daniel Boone had returned home from the Braddock Expedition and on August 14, 1756, had married Rebecca Bryan, a neighbor in the Yadkin River Valley whose brother married one of Boone's sisters.

The couple initially lived in a cabin on his father's farm.

They eventually will have ten children.

Their youngest son, Nathan Boon, will be the first white man born in Kentucky.

Boone supports his growing family in these years as a market hunter and trapper, collecting pelts for the fur trade.

Almost every autumn, Boone goes on "long hunts", extended expeditions into the wilderness lasting weeks or months.

Boone goes alone or with a small group of men, accumulating hundreds of deer skins in the autumn, and trapping beaver and otter over the winter.

The hunt follows a network of bison migration trails, known as the Medicine Trails.

When the long hunters return in the spring, they sell their take to commercial fur traders.

Such frontiersmen often carve messages on trees or write their names on cave walls, and Boone's name or initials have been found in many places.

One on a tree in present Washington County, Tennessee reads "D. Boon Cilled a. Bar [killed a bear] on [this] tree in the year 1760".

A similar carving, preserved in the museum of the Filson Historical Society in Louisville, Kentucky, reads "D. Boon Kilt a Bar, 1803."

The inscriptions may also be among numerous forgeries of the famous trapper, part of a long tradition of phony Boone relics.

In 1758, a conflict erupts between the British forces and the Cherokee, their allies in the French and Indian War (which continues in other parts of the continent).

After the Yadkin River Valley was raided by Cherokee, the Boones and many other families flee north to Culpeper County, Virginia.

Boone serves in the North Carolina militia during this "Cherokee Uprising".

His militia expeditions deep into Cherokee territory beyond the Blue Ridge Mountains will separate him from his wife for about two years.
