Chief #Kintpuash (aka #CaptainJack) and three #Modoc warriors were hanged on #ThisDayInHistory in 1873 for their part in the well-fought #ModocWar – a response to the #CaliforniaGenocide. The remaining 153 members of his band were held as prisoners of war in Oklahoma until 1909.

On #ThisDayInHistory in 1992, #SinéadOConnor hurt her career by tearing up a picture of #PopeJohnPaulII on #SNL. She was made a pariah, driven to break-downs and obscurity, but she was right to call out the #ClericalSexualAbuse that the #Vatican has long covered up and excused.

The #UnitedNations #HumanRightsCouncil voted, on #ThisDayInHistory in 2017, to condemn application of the #DeathPenalty for #apostasy, #blasphemy, #adultery, and #homosexuality. The United States and twelve other countries, like #SaudiArabia & #Iraq, voted against the resolution.

#Vercingetorix, a leader of the #Celtic #Gauls, surrendered to the #Roman forces of #JuliusCaesar on #ThisDayInHistory in 52 BCE, ending the siege & #BattleOfAlesia. #Caesar's #genocidal conquest of what eventually became France was lionized in his propaganda work #TheGallicWar.

The #IDF struck #Dahiya (#Dahieh), #Lebanon, again on #ThisDayInHistory in 2024. Such attacks on civilian areas are discussed in the #DahiyaDoctrine (named for the #Beirut suburb), which advocates large-scale destruction of #infrastructure & residential areas to pressure leaders.

#Mussolini's Italy invaded #Ethiopia on #ThisDayInHistory in 1935, launching the #SecondItaloAbyssinianWar. The #Fascist forces used tanks, #ChemicalWeapons, and #ConcentrationCamps to subjugate the only African country not to have been colonized. The world stood by and watched.

A US AC-130 gunship attacked a hospital in #Kunduz, #Afghanistan, run by #MédecinsSansFrontières (#DoctorsWithoutBorders) on #ThisDayInHistory in 2015. At least 42 were killed and 30+ wounded. #USAF changed its story twice, and the gunship crew questioned the strike's legality.

#Mormon settlers in #Utah, on #ThisDayInHistory in 1853, committed the #NephiMassacre. Seven men, one woman, and two children from the peace-seeking #Goshute Indigenous nation were invited into the #LDS fort. The men were beaten & shot dead; the woman and children were enslaved.

In the #TlatelolcoMassacre, on #ThisDayInHistory in 1968, the #Mexican government (with #CIA support) murdered 400 #student #protesters and savagely beat a thousand. The students were upset at money wasted on the upcoming #OlympicGames in light of extreme poverty in the country.

On #ThisDayInHistory in 1937, US-backed dictator #RafaelTrujillo of the #DominicanRepublic began a #genocide of #Haitians near the border in what's apocryphally called the #ParsleyMassacre, killing up to 35,000. Demonization of Haitians often used #Vodou as a mark of identity.

#Cryptofascist commentator #JacksonHinkle stopped pretending, on #ThisDayInHistory in 2024, that his criticism of Israel was rooted in #antiZionism, and admitted instead, quite bluntly, to his #Judeophobic and #antisemitic #ChristianNationalism. Be careful who you follow, people.

Sailing a zig-zag at 28+ knots to evade submarines, #RMSQueenMary, filled with troops for the war in Europe, rammed ageing cruiser #HMSCuracoa on #ThisDayInHistory in 1942, cutting her in half. Unable to stop and assist, QM had to leave 337 men to drown; 101 were later rescued.

The #GreatCheeseRiot began in #Nottingham on #ThisDayInHistory in 1766. Women angry at overpriced #cheese at the annual #GooseFair stole wheels of it. When some were arrested, the building holding them was attacked. Soldiers were then used to suppress the #anticapitalist revolt.

#MohammedBinSalman, de facto leader of #SaudiArabia, oversaw the assassination in #İstanbul, on #ThisDayInHistory in 2018, of Saudi dissident and #WashingtonPost reporter #JamalKhashoggi. His body was dismembered and destroyed, and the murder was covered up with US assistance.

#BalianOfIbelin surrendered the city of #Jerusalem to #SalahAdDin (#Saladin) on #ThisDayInHistory in 1187 after a brief siege. Salah ad-Din ensured the worship rights of all faiths, and aside from ransoming nobles, allowed passage to Christian lands for the remaining #Crusaders.

#YosemiteNationalPark, one of the most beautiful places on Earth, was established by Congress on #ThisDayInHistory in 1890, preserving for future generations (and saving from loggers & developers) a pristine #California forest of soaring trees and awesome mountains & waterfalls.

#Union #DirectAction has, on rare occasion, gone too far. Between 1906 & 1911 the #IW carried out 110 bombings of ironworks, mostly minor. But in 1910 on #ThisDayInHistory, a member blew up the #LosAngelesTimes building, killing 21 & injuring 100+; a record crime for #California.

We lost #KrisKristofferson on #ThisDayInHistory in 2024. Many tributes mentioned his consolation of #SinéadOConnor, a truly touching moment. But I'd like to direct you to another side of his humanity – his earnest acknowledgement of, and real concern for, the #Palestinian plight.

The #WaltDisneyWorld resort opened to the public on #ThisDayInHistory in 1971, five years after namesake #WaltDisney's death. Specifically, the #MagicKingdom opened, its equivalent to #Disneyland. The next park on the site, #EPCOTCenter, also opened on #ThisDayInHistory, in 1982.

#SenecaVillage, in #NewYorkCity, was a vibrant community of free #Black Americans and Irish & German #immigrants. In 1857 the city seized it all through #EminentDomain and evicted everyone there, finishing the process on #ThisDayInHistory, and built #CentralPark open its bones.

Ever unwilling to respect the national sovereignty of other countries, Israel on #ThisDayInHistory in 1985 carried out #OperationWoodenLeg. In it, the #IDF bombed the #PLO's headquarters in #Tunisia – the country to which #Israel agreed to evacuate the PLO when it left #Lebanon.

On #ThisDayInHistory in 1946, the sentences in the #NurembergTrials were handed down. 12 #Nazis were condemned to death. Meanwhile, countless thousands of politicians, officers, commandants, & #WarCriminals were reintegrated into society and government. The Nazis never went away.

Israel invaded #Lebanon again on #ThisDayInHistory in 2024, with the #IDF proceeding to the #LitaniRiver, viewed by #GreaterIsrael advocates as #Israel's natural northern border. This was its fifth such invasion since 1978, and its sixth counting the incursions during the #Nakba.

#AlexanderTheGreat, so-called, defeated #DariusIII, and the #Achaemenid #PersianEmpire, in the #BattleOfGaugamela on #ThisDayInHistory in 331 BCE. Alexander got lucky when the #Persian cavalry rushed to loot his supply train rather than attacking his exposed #phalanx from behind.

(2 of 2) The #ElaineMassacre from #ThisDayInHistory in 1919 began with #Black farmers organizing for better pay and facing a white mob that opened fire on them. They shot back, and the mob killed up to 800 of them, with dozens of survivors imprisoned for supposedly inciting it.

(1 of 2) When #conservatives talk about a right to #SelfDefence, they do not mean against them, and they fear losing control of the state monopoly of violence. On #ThisDayInHistory in #Elaine, #Arkansas, in 1919 they killed hundreds of #Black innocents for daring to fight back...

The #CaravanOfDeath set out on #ThisDayInHistory in 1973. A #Chilean Army #DeathSquad, it served the violent #FarRight dictatorship of #AugustoPinochet by traversing the country, south to north, torturing, mutilating, & killing 97 #leftists, and tossing them into unmarked graves.

Racial #segregation is far from a uniquely American evil, and on #ThisDayInHistory in 1953, #communist boxer #LenJohnson faced it in the #OldAbbeyTaphouse in #Manchester, England. Refused service for being #Black, he organized a 200-strong picket of the pub that desegregated it.

The #MunichAgreement between #NaziGermany, Italy, the UK, and France was signed on #ThisDayInHistory in 1938. It sold out #Czechoslovakia, passing their #Sudentenland region to Germany... who then exceeded this by seizing the rest of #Czechia six months later with no consequence.

The first of the great #FreeSpeechFights of the #IWW was on #ThisDayInHistory in 1909, in #Missoula, #Montana, to combat ordinances against public #FreeSpeech by #union members. They lined up, spoke, got arrested, filled the gaols, and got the laws changed. #PeoplePower works.

Join me in some Schadenfreude for the death, on #ThisDayInHistory in 2024, of German #Neonazi #AndreasMünzhuber. The treasurer for #TheThirdWay tripped on an exposed root on #Untersberg mountain in Hitler's beloved #BerchtesgadenAlps, falling 60 metres to a richly deserved death.

The #LeagueOfNations #MandateSystem was a thinly-disguised form of #colonialism in which a Mandatory power got to refashion a place into a permanent subordinate. The #FrenchMandate for #Syria & #Lebanon, and the #BritishMandate for #Palestine, began on #ThisDayInHistory in 1923.

At #Istaliff, #Afghanistan, on #ThisDayInHistory in 1842, a British force decided, as revenge for anti-imperialist insurgency, to butcher a whole town. They set out to kill every male in a population of 15,000, then burnt the houses & orchards, leaving women & children to starve.

Demanding food during a famine and trying to prevent the rich from exporting it at a profit are moral acts. But on #ThisDayInHistory in 1846, British Royal Dragoons opened fire on starving people who tried to seize grain from the docks and from bakeries in #Dungarvan, #Ireland.

Organizing leftists can be a bit like herding cats but is crucial for saving this world. On #ThisDayInHistory in 1913 the #FirstInternationalSyndicalistCongress began in #London, a great success with heated debates. #Syndicalists aim for a stateless order run by workers councils.
