#CincoDeMayo is actually #BattleOfPueblaDay and commemorates a #Mexican victory over #France in 1862 on #ThisYearInHistory. France subsequently took #MexicoCity and they did not fully leave #México until 1867, but the #BattleOfPuebla remains a point of pride for #Californios.

The #MexicanAmericanWar ended early in #California, when on #ThisDayInHistory in 1847 the #TreatyOfCahuenga was signed. It guaranteed rights to the Spanish-speaking #Californios, who became US citizens. It was signed on that side by #AndrésPico, who later served state government.
