This founding member of the Kurdish anti-Ankara martyrology had sparked a momentarily-successful rising against Turkey, fired by grievances that have not ceased to resonate since.
The secular nationalist Kemal Ataturk‘s intent to “Turkify” its peoples. The Kurdish populace’s frustrated national ambitions, indifferently bartered away by distant great powers dismembering the Ottoman Empire.* Ataturk’s abolition of the Caliphate.
“Oppressive and vile towards the Kurds,” Sheikh Said declared. (pdf)
For several years we have been able to read in the newspapers and official documents about the oppression, insults, hatred, and enmity that the Turk Republic [sic] accords to the Kurdish notables and dynasties. There is a lot of evidence available from authentic sources that they want to subject the Kurdish elite to the same treatment to which they subjected the Armenians
The February revolt quickly made him master of the majority-Kurdish eastern province of Diyarbakir, but a massive Turkish counterattack drove him east, encircled him, and had the Sheikh in irons by mid-April.
The government arrogated martial law powers to itself and appointed Orwellian courts called Independence Tribunals to prosecute Kurdish elites, rebels or no. (Some Kurdish intelligentsia were hailed to Diyarbakir from Istanbul.) Hundreds hanged, without even counting wholesale extrajudicial retribution against Kurdish civilians.
the repression of the 1925 rising was accomplished with a brutality which was not exceeded in any Armenian massacres. Whole villages were burnt or razed to the ground, and men, women and children killed.

* A past-is-prologue artifact from the time: the “Issue of Mosul“, a prickly international relations dispute over control of the historic city, accurately suspected to be sitting on a lot of oil.
Turkey claimed it as part of its historic heartland, but Great Britain had seized it just before World War I ended and wound up hanging onto it for the embryonic Iraqi state. Kurds who also considered it part of their homeland got short shrift altogether. It’s still disputed today among Iraqis, situated as it is just on the edge of Kurdish Iraq.
