#OTD (ish) 500 years ago the conquistadors struggled from the Aztec capital, Tenochtitlan, after what became known as the 'Night of Sorrows'. Today @amyfullermorgan @claudiajrogers & I are going to unpick this contested ‘anniversary’. Follow here & #NocheTriste2020 for more! 1/ Image
Perhaps ⅔ of the Spanish & hundreds of Indigenous allies were slaughtered escaping the capital at night, after the Aztecs (correctly, Mexica or Tenochca) ended their hospitality when the conquistadors massacred unarmed Aztec warriors at the Toxcatl festival. #NocheTriste2020 2/ Image
This brought to an end months of careful diplomatic manoeuvring by Cortés & the Mexica, & threw Mexico into open war. @amyfullermorgan wrote more about the events of that night for BBC History Magazine, if you'd like a brief recap!… #NocheTriste2020 3/

#OTD in 1940, the USSR began the third wave of deportations from Polish eastern borderlands occupied by the Soviets on Sept. 17, 1939.This deportation targeted Polish civilians who fled from western to eastern Poland following the German invasion of #Poland on Sept. 1, 1939.#WWII
Also targeted were professionals, merchants, the intelligentsia, and those who did not accept Soviet passports. Roughly 80 percent of these deportees were Jewish; the remainder included Poles, Belarusians, and Ukrainians.
In December 1939, the USSR and Germany agreed to repatriate refugees from their respective occupied Polish territories. Those in the Soviet zone who wished to return to the German zone were required to register with the German authorities and vice versa.

#OTD in 1651 began a huge (one of the largest in the 17th century) battle of Berestechko between the army of the Polish-Lithuanian Commonwealth, commanded personally by King John II Casimir Vasa and a combined Cossack-Tatar army
commanded by Bohdan Khmelnitsky & Khan Islam III Giray. The 10 day battle (which actually consisted of a 3 day field battle followed by a 7 day siege of a fortified Cossack camp, after the Tatars ran away talking Khmelnitsky with them) ended with a total Commonwealth victory
appeared to put an end to the Khmelnytski Uprising. However the hostility between the king and the nobles allowed the Cossack forces to recover and the war continued after a brief ceasefire at Bila Tsyrkva.
Both armies were enormous although their exact sizes are uncertain. The

Fred Hoyle, who proposed a steady state model of the Universe and coined the name "Big Bang" to ridicule a rival theory, was born #OTD in 1915. He pioneered nucleosynthesis, but advocated unscientific theories about the origin of life and was known to make strange racist claims.
For starters, his steady state theory was wrong. He was sure it was right, and posited all sorts of wild ideas to try to keep it going, which did his scientific reputation no favors.
Hoyle accidentally coined the term “Big Bang” for our prevailing model of the early Universe in 1949. Defending his steady state theory on the BBC he criticized "the hypothesis that all matter of the universe was created in one big bang."

Alan Turing who revolutionized our understanding of machines, intelligence and computation was born #OTD in 1912. Turing played a critical role in cracking the German enigma code during WW2. Hounded by Britain's regressive anti-homosexual laws, he committed suicide in 1954.
Two of Turing's many important papers laid the foundations of computer science. His 1936 paper introduced the Turing Machine and, hinting at Gödel's earlier papers, proved that a general procedure for Hilbert's "decision problem" is impossible. Alonzo Church proved the same thing
His 1950 paper effectively asked whether a machine is intelligent by proposing the Imitation Game of Turing Test, a game in which a human interacting with a machine would receive responses that would be indistinguishable from that given by humans.

Mathematician Hermann Minkowski was born #OTD in 1864. He proposed a unified four-dimensional spacetime as the proper arena for the work of Maxwell, Lorentz, and Einstein.
Image: MacTutor History of Mathematics Archive
Today we refer to this 4-dimensional manifold, equipped with a peculiar notion of distance, as the Minkowski spacetime. Let me explain how it is different than the Newtonian picture of space and time that preceded it.
Suppose I observe two events. From my point of view, each one happens at a particular time t and a specific place labeled by three coordinates x, y, z. Maybe they occur at the same time but different places, or vice-versa. Maybe they differ in both place and time.

#OTD in 1865, enslaved African Americans were notified of their freedom by Union troops in Galveston Bay, TX—two years after the Emancipation Proclamation was issued.

Known as #Juneteenth, this day is widely celebrated as the end of chattel slavery in the U.S. #APeoplesJourney
Though it has long been celebrated among the African American community, it is a history that has been marginalized & still remains largely unknown to the wider public. The legacy of #Juneteenth shows the value of deep hope & urgent organizing in uncertain times. #APeoplesJourney
Although the Emancipation Proclamation was made effective in 1863, it could not be implemented in places still under Confederate control, some enslaved people would not be free until much later.

Short history thread in honor of a special day:

#Juneteenth is a holiday that commemorates the end of slavery in America, but the proclamation issued by the Union army in Texas on June 19, 1865, did not end slavery in the United States. (1/3)
Slavery remained legal in Kentucky and Delaware until the ratification of the 13th Amendment was declared on December 6, 1865. Unlike the border states of Maryland and Missouri, Kentucky and Delaware had refused to abolish slavery by state action. (2/3)
Maj. Gen. Gordon Granger's General Orders No. 3—the final enforcement of the Emancipation Proclamation, issued on June 19, 1865—brought freedom to about 250,000 enslaved people in Texas, the last Confederate state occupied by the Union army.… (3/3)

#OTD in 1815, between 11.50am and 1.30pm (accounts differ), the 80 guns of Napoleon's Grande Batterie fired the opening salvoes of the Battle of #Waterloo Image
One of the most astonishing tales of the battle is that of Sgt John Shaw of the 2nd Life Guards, based at La Haye-Sainte on the morning of the 18th of June 1815 who was heavily involved in the day's fighting Image
Shaw had made a name for himself before the battle as a talented boxer. He gained notoriety following a street brawl with 3 toughs who foolishly taunted him near London's Portman Square from which he emerged triumphant. His officers introduced him to Five Courts Club and boxing..

#OTD Election 1970

Harold Wilson is defeated and Ted Heath becomes Prime Minister

Fifty years on, a look back at the ‘heatwave election’ as Wilson takes his campaign to 'the people', tensions rise over race and immigration and England look to defend their World Cup in Mexico... Image
Wilson called the election for June 1970 after a turnaround in the party’s fortunes.

In 1969 the Tories held a poll lead of 19% and many within Labour were disgruntled – with issues such as price rises, pound devaluation, Vietnam and prescription charges
But a change economic fortunes – such as a boost in the export figures – meant that by May 1970 Labour held a 12% lead in the polls.

Wilson feared that a delay until October 1970 would allow the Conservatives to spend £2 million on a Summer advertising campaign Image

#OTD in 1800 Napoleon, then the 1st Consul of the Republican of France, almost lost the crucial battle of Marengo. The final victor was due to the Austrians celebrating too early, and the timely arrival and a superb charge by general Desaix, which cost him his life. When Desaix
arrived at the battlefield there was the following conversation between him and Bonaparte (according to Bourienne)
Bonaparte: Well, what do you think?
Desaix: “This battle is completely lost, but it is only two o’clock - there is time to win another.”
The death of general Desaix
was a great blow to Napoleon. He was not only considered one of the most brilliant of the younger officers in revolutionary France, but he was also one who very deliberately and farsightedly attached his future to Bonaparte’s. At the time when Napoloeon was making his name in

The night before on the 13th June, the prisoners were taken to the Jewish Baths where they bathed and had something to eat. Food was provided by the local women at the Red Cross.
In the early hours of the 14 June 1940, the prisoners from Tarnów prison awoke from a sleepless and restless night at the Jewish baths, where they were taken the previous day. Lined up into rows of five, with their escorts, they set off to Tarnów train station. (3)

James Clerk Maxwell was born #OTD in 1831. He showed that electric and magnetic fields are aspects of a single phenomenon, determined the equations that govern it, and concluded that light and other forms of radiation are electromagnetic waves.
Image: J.C. Maxwell Foundation
As a student at Cambridge, James Clerk Maxwell hated homework and wrote long poems about it.…
Maxwell began his work on electromagnetism in the mid-1850s. He was inspired by Michael Faraday's "lines of force" approach –– today we would call them "fields." Maxwell's goal was to collect everything known about electricity and magnetism into a single, unified theory.

#OTD in 1967 the Supreme Court stuck down laws banning interracial marriage in Loving v. Virginia.

In September 1954, John Billy & his group, "The Honey Boys," were performing at an all-white club in Baltimore when he spotted Shirley Howard, a white woman, and asked for a dance.
Their connection was immediate. Shirley's mother insisted she stay away from John, but there was no stopping their love. When Shirley gave birth to their first child two years later, their son was taken to an orphanage & Shirley was arrested.
She spent a day & a half in jail before paying $1,000 bail for "permitting herself to be begotten with child by a negro or mulatto." Shirley was the only person be prosecuted in MD under the law.

"On a Heuristic Point of View Concerning the Production and Transformation of Light," Einstein's paper that asserted the reality of quanta to explain the photoelectric effect, was published #OTD in 1905.
Five years earlier, Planck proposed the emission and absorption of radiation in finite chunks as a way of explaining the emission spectrum of a black-body. But he didn’t think it was a fundamental property of light; he thought it was a consequence of how matter & light interact.
Einstein opens his paper by acknowledging that the existing theory of light, continuous waves governed by Maxwell's equations, gives an immensely satisfying and probably irreplaceable description of optical phenomena as they were understood at the time.

#OTD we celebrate Kabir Jayanti in remembrance of the great poet that walked this land. Kabir Das was a 15th-century Indian mystic poet and saint, whose writings influenced Hinduism's Bhakti movement and his verses are found in Sikhism's scripture Guru Granth Sahib.
His early life was in a Muslim family, but he was strongly influenced by his teacher, the Hindu bhakti leader Ramananda.Kabir was born in the Indian city of Varanasi but spent most of his life in the city of Faridabad near Delhi.
Kabir suggested that Truth, which he often called Raam, is with the person who is on the path of righteousness, considered all creatures on earth as his own self, & who is passively detached from the affairs of the world. To know the Truth, one must drop the "I" or the ego.

#OTD 1945. Clement Attlee responds to Churchill’s ‘Gestapo’ speech with an attack on Conservatism:

‘For years every attempt to remedy these crying evils was blocked by the same plea of freedom for the individual. It was in fact freedom for the rich and slavery for the poor’
On the 4th June, Churchill kicked off the 45 campaign with his first election broadcast:

‘there can be no doubt that Socialism is inseparably interwoven with Totalitarianism and the abject worship of the State’
‘there is to be one State to which all are to be obedient in every act of their lives. This State is to be the arch-employer, the arch-planner, the arch-administrator and ruler, and the arch-caucus boss’
