The #EmpireMineStrike began on #ThisDayInHistory in 1950, to oppose pay #discrimination and #segregated housing. Eight months in, they were barred from picketing and their wives stepped in. After 15 months the company gave in. The 1954 film #SaltOfTheEarth documented the #strike.

Massive #CollectivePunishment was routine for British forces in the #AmericanRevolution, such as that on #ThisDayInHistory in 1775, when a squadron of the #RoyalNavy opened fire on the unresisting town of #Falmouth, #Massachusetts, burning 3/4 of it to the ground over two days.

The #SundayTimes published a front-page article on #ThisDayInHistory in 1971,detailing the #torture methods used by the British state's occupation forces in #NorthernIreland. This led to some practices being banned in 1972 though routine torture of prisoners continued until 1999.

#KeplersSupernova, a Type Ia #supernova, was observed by #JohannesKepler from #ThisDayInHistory in 1604, eight days after being recorded by #LodovicoDelleColombe. It was discussed in #Kepler's book #DeStellaNova and called a new star in the foot of the #constellation #Ophiuchus.

Calling all resistance to Western imperialism and racism "#terrorism" is dishonest, manipulative rhetoric. The war criminal #MargaretThatcher insisted on #ThisDayInHistory in 1987 that she could not meet with #SouthAfrica's #ANC (or the #IRA or #PLO) because they were terrorists.

The #1961ParisMassacre was #ThisDayInHistory, when the French state met an #Algerian #FLN protest with savage violence: ~200 people beaten to death & thrown in the river. The #police were led by #MauricePapon, a #Nazi collaborator & #WarCriminal who went unpunished for this act.

The #1973OilCrisis, which began on #ThisDayInHistory, was a direct result of US and European foreign policy, specifically sending arms to Israel during the #1973War/#YomKippurWar. The #OPEC embargo saw global prices surge, but caused no change in the policies of Western powers.

On #ThisDayInHistory in 1962, the #CubanMissileCrisis began. The US provoked the #USSR with an aggressive nuclear posture, later backing down and removing our missiles, but to this day US #propaganda has people believing the #Soviets the aggressor. The #ColdWar legacy is a curse.

#Black runners #TommieSmith and #JohnCarlos raised fists in a #BlackPower salute on #ThisDayInHistory in 1968 at the #MexicoCityOlympics, protesting #racism. Widely hailed now as an iconic image, at the time it led to severe censure and the virtual end of their sporting careers.

#JohnBrown and a dozen #abolitionists seized the armoury at #HarpersFerry on #ThisDayInHistory in 1859, hoping to arm a #slave uprising. Slavery never truly ended in the US, and all it takes for evil systems to flourish is for good people to do nothing. #JohnBrownDidNothingWrong

Being yourself is a revolutionary act. On #ThisDayInHistory in 1854, the #Irish author #OscarWilde was born. Best known to-day for his plays, his sense of style, and being imprisoned for homosexuality, he was also a committed #anarchist and #socialist, and a superb social critic.

Monarchy and aristocracy are, by definition, crimes against humanity and should be opposed in the name of freedom. On #ThisDayInHistory in 1793, French Queen #MarieAntoinette was executed for high treason by the First Republic. Celebrate with a little cake..? 😉 #EatTheRich

Another #IDF #EthnicCleansing #WarCrime was seen in #Mhaibib/#Muhaibib, #Lebanon, on #ThisDayInHistory in 2024. Troops entered the village (which contained some ancient religious sites), drove out the population at gunpoint, rigged every house with explosives, & destroyed it all.

The #BlackPantherParty, a #socialist #antiracist group, was founded in #Oakland, CA, on #ThisDayInHistory in 1966 by #HueyPNewton & #BobbySeale. It operated health clinics and provided free food to children, scaring Washington into unleashing #COINTELPRO and killing its leaders.

#Pacifist #DavidMiller burned his #VietnamWar draft card on #ThisDayInHistory in 1965, He served two years in prison for his principled stand against #imperialism and exercising his #FirstAmendment right of protest. Thankfully the US ended conscription, sparing others his fate.

The #CassiniHuygens space probe to the #Saturn system, a joint project of #NASA, #ESA, & #ASI, launched from #CapeCanaveral, Florida, on #ThisDayInHistory in 1997. The #Huygens lander touched down on #Titan in 2005, and the highly successful #Cassini mission itself ended in 2017.

The #SalvadoranCivilWar began with a #coupdétat on #ThisDayInHistory in 1979 to overthrow #ElSalvador Pres. #CarlosHumbertoRomero. The twelve-year conflict killed 100,000 people, created over a million #refugees, and caused instability that has never fully ended for the country.

A spiritual-intellectual descendant of #Nietzsche who shares his birthday, #MichelFoucault was born on #ThisDayInHistory in 1926. The French philosopher and historian expanded Nietzsche's genealogical method and critique of #power, notably in 1975's seminal #DisciplineAndPunish.

Classical philologist & iconoclastic philosopher #FriedrichNietzsche was born in Röcken, Saxony-Anhalt, Germany, on #ThisDayInHistory in 1844. Subject to crippling #migraine all his life, with a father who also died young & in agony, Nietzsche's work is a tribute to perseverance.

#ThomasSankara, revolutionary leader of #BurkinaFaso, was murdered in a #coup on #ThisDayInHistory in 1987 by #BlaiseCompaore, whose rule was deemed more acceptable by the #capitalist/#imperialist powers. He was finally convicted in 2022 for killing the Marxist leader and gaoled.

A full million #Canadians went out on a one-day #strike on #ThisDayInHistory in 1976 against widely-hated wage and price controls. PM #PierreTrudeau had broken a campaign pledge against such policies, and this #labour action forced the #Liberal government to end #WageControls.

On #ThisDayInHistory in 1977, #Christian #bigot and anti-#LGBTQ campaigner #AnitaBryant got a pie to the face during a public appearance. Folding hate and judgement into Christian messaging is a betrayal of the #Gospel message. Actual love involves acceptance, not condemnation.

Building on what #RichardNixon had done, #RonaldReagan proclaimed another #WarOnDrugs on #ThisDayInHistory in 1982. These policies of #Prohibition only strengthen #cartels & criminals, but that is the point, as they allow expansion of the #PoliceState and racist #CarceralSlavery.

During the US #RevolutionaryWar British forces sowed chaos by offering freedom to #Black slaves who joined the army. Facing a hard siege, #LordCornwallis betrayed this promise on #ThisDayInHistory in 1781, driving them from #Yorktown to be cut down by the Americans or reënslaved.

The use of force against #union organizers has been normal for centuries and must be stopped. On #ThisDayInHistory in 1999 in #Guatemala, 200 hired thugs forced union leaders at a #DelMonte subsidiary to resign on threat of execution and to read a statement of surrender on radio.
