The #31MarchIncident, so named due to the #OttomanEmpire's Rumi Calendar then in use, was a reactionary attempted coup against the #YoungTurk/#CUP government on #ThisDayInHistory in 1909. It led to #AbdülhamitII's fall and the appointment of #MehmedV as a constitutional monarch.

Within a crucible of #GrecoTurkishWar & the aftermath of #WorldWarI, #Türkiye was born from ashes of the #OttomanEmpire. Its first constitution was adopted #ThisDayInHistory in 1921, establishing #nationalism as its core principle, thus inheriting the worst of the #YoungTurk era.
