History.
The Vilayet of Sivas was created in 1867 when eyalets were replaced with vilayets under the "Vilayet Law" (Turkish: "Teşkil-i Vilayet Nizamnamesi") and was dissolved in 1922 by Atatürk's reorganization.
From 1913 to 1916, Ahmed Muammer was the "Vali" (governor) of the vilayet, and he has been accused of being complicit in actions against the Armenian population.
