When #Mongols threatened the #MiddleEast, #Egypt's #MamlukSultanate gave an olive branch to remaining #CrusaderStates, offering peace if they allied against a common threat. When the #Crusaders refused, the #Mamluks turned on them, and on #ThisDayInHistory in 1268 took #Antioch.

The first #Crusaders to leave for the #HolyLand — the #PeoplesCrusade that left before the formal armies of the #FirstCrusade — set their brutal tone by engaging first in bloody #pogroms against European #Jews, like in the #WormsMassacre of 1000 Jews on #ThisDayInHistory in 1096.

The seventh country successfully to build & detonate a #NuclearWeapon was #India, which did so in 1974 on #ThisDayInHistory. India waited until 1998 to resume testing nukes. Throughout its #nuclear history it has received technical aid from the United States and other countries.

The #GwangjuUprising against the US-backed dictator of #SouthKorea began on #ThisDayInHistory in 1980. Peaceful protesters were shot and stabbed to death, but they quickly raided #police stations for weapons and fought back. The régime killed up to 2000 before regaining control.

It took until 1990 on #ThisDayInHistory for the UN #WorldHealthOrganization (#WHO) to remove #homosexuality from its list of psychiatric diseases. #LGBTQIA people have always existed within several natural spectra of neurological & chemical variation. Bigots need to get over it.

An all-white male jury in #DadeCounty, FL, acquitted four #police officers in the brutal killing of #ArthurMcDuffie, a #Black man and former #Marine, on #ThisDayInHistory in 1980. The #ArthurMcDuffieRiots, aka #1980MiamiRiots, that began the next day, were a predictable response.

A key part of the #CubanRevolution, the #FirstAgrarianReformLaw was signed by #FidelCastro on #ThisDayInHistory in 1959. It seized plantation lands and distributed them directly to small #CollectiveFarms (#coöperatives) and to larger state-run farms, and abolished #rent for land.

The United States briefly nationalized its #railroads on #ThisDayInHistory in 1946, specifically to prevent a #strike. When the union walked out anyway, Pres. #Truman threatened to draft workers into the military and use troops to run the trains. The US is a tyrannical oligarchy.

The #CatonsvilleNine, a group of #Catholic #AntiWar activists incl. Fr #DanielBerrigan, on #ThisDayInHistory in 1968 entered a #SelectiveService office in Maryland, took 378 draft files from it, and burnt them outside with home-made #napalm, "burning paper instead of children".

#Segregation in #PublicSchools was declared illegal in a unanimous #SCOTUS decision on #ThisDayInHistory in 1954. The #BrownVBoardOfEducation of Topeka ruling helped to divide US politics along racial lines, with one party increasingly courting #WhiteSupremacists angered by it.
