The Sasun uprising or Sasun rebellion of 1904 (, Sasuni yerkrord apstambut'yunĕ, literally Second Sassoun resistance) was an uprising by Armenian militia against the Ottoman Empire in Turkey's Sason region in 1904. The empire wanted to prevent the formation of another semi-autonomous Armenian region in the eastern vilayets after its defeat in the First Zeitun Resistance. In Sason, the Armenian national liberation movement recruited young Armenians.
