The 1896 Ottoman Bank Takeover (Armenian: ) was the seizing of the Ottoman Bank in Constantinople, Ottoman Empire on August 26, 1896 by members of the Armenian Revolutionary Federation (Dashnak Party). In an effort to raise further awareness and action by the major European powers, twenty-eight armed men and women led primarily by Papken Siuni and Armen Karo took over the bank which largely employed European personnel from Great Britain and France. Stirred largely due to the inaction of the European powers in regards to pogroms and massacres instigated by the Sultan Abdul-Hamid II, the Dashnak members saw its seizure as their best attempt to bring full attention to the massacres.
