Of Armenian descent, Haig Tiriakian was born in Trabzon, Ottoman Empire in 1871. In 1893, Tiriakian then went to Nancy, France where he studied agriculture until 1896. During his time in Europe, Tiriakian joined the Armenian Revolutionary Federation where his first assignment was assigned the planning of the Ottoman Banktakeover. The takeover was planned in order to raise further awareness and action by the major European powers. The bank was largely employed European personnel from Great Britain and France. Stirred by the inaction of the European powers in regards to Hamidian massacres, the Armenian Revolutionary Federation members saw its seizure as the best way to bring full attention to the massacres. The organizational planning of the takeover required Tiriakian to visit various countries around the world before the takeover took place. Tiriakian eventually took part in the seizure along with other Armenian political activists such as Armen Garo and Papken Siuni. Tiriakian describes the event as follows: After the takeover concluded, Tiriakian was one of many participants who were exiled then shipped to Marseille, France. While in exile, Tiriakian attended the Second General Congress of the Armenian Revolutionary Federation held in 1898 in Tbilisi, Georgia which had him appointed the Responsible Body for the Cilicia region. After making a brief visit to Alexandria, Egypt, Tiriakian returned to the Ottoman Empire in secret. One of the main goals of his return was to gather money from wealthy Armenians in order to help fund the Armenian revolutionary movement. However, since the Ottoman authorities had an arrest warrant for him, he was caught and sent to life imprisonment in Bodrum. After the Young Turk Revolution in 1908, Tiriakian was set free and returned to Constantinople. In Constantinople, he became a publicist and manager of the Azadamard Armenian newspaper.
