He worked as the head of the Ottoman Archive Department at the Prime Ministry General Directorate of State Archives in 1989 and in 1990 he became an assistant to the General Director. He started the automation [or more accurately, cleansing] of the Ottoman Archive in this period. He left his office there in 1992.
Explanation of the Genocide Period
This is an interview with Yusuf's explanation of what actually happened during the genocide, directly from a site called "unrealarmeniangenocide". Of course there is no data to be found anywhere backing up his claims, and in fact I don't even see his numbers adding up here in his answers themselves to begin with. I have italicized the passages which need special scrutiny. There are also many interesting admissions.
T. AKYOL: The forced emigration has been known in general, people don't know the details. The Ottoman Empire decided to send Armenians from east Anatolia to Syria because Armenians were in cooperation with Russians. During this forced emigration, there had been lots of fights and both sides had faced lots of deaths.
Prof. Dr. HALAÇOĞLU: The forced emigration law had been made law on 26. May 1915. Armenian genocide celebration day was 24. April 1915. Because on April 24, 1915, the Armenians who were the ringleaders of them in İstanbul were taken into custody. The power of Armenian action was decreased by this decision. But there had been fights before this date and Armenians did attack to innocent villagers rather than to the Turkish armies in Caucasia and the villagers made counter attacks towards Armenians. Armenian had written their fatal actions and their genocide on their newspapers and magazines.
Russia, England, France and Germany have coerced the Ottoman Empire to sign "the reform pact" (Islahat antlaşması) on 8 February 1914. By this pact, they wanted to establish an autonomous republic of Armenia and the Ottoman Empire had to accept this wish and appoint the people who were commended by Western countiries to governor of a province in this region. Besides this, Armenian became the official language in the region. The Ottoman Empire wanted Armenians get away from the region after first world war. By the suggestion of Enver Pahsa, Armenians in the east anatolia had to migrated to Syria on 27 May 1915. The Armenian convoys which had no securities provide by the Ottoman Empire had been under attacked by the villagers. The populations of Armenians who had forced to immigrate had benn recorded on the ottoman archives and it was 438,758.
382,148 of them had arrived to housing regions. The difference was 56,610. 500 of them were killed in the region between Erzurum-Erzincan by highwaymen. Approximately 2,000 of them were killed in Meskene and 2,000 of them were killed in Mardin by highwaymen. 5-6,000 people were killed in the Dersim region by the villagers in the region. But the absolute number of deaths was not written in the ottoman archives.
T. AKYOL: You have mentioned approximately 500 000 Armenians. But according to the Ottoman archives the Armenian population was 1.4 million. What happened to 900,0000 people?
Prof. Dr. HALAÇOĞLU: There were other Armenians who had gone to Caucasia, Iran , America and France except 458,000 forced immigrants. It was mentioned in the Armenians letter in the ottoman archives that 100,0000 Armenians were in America. Mubar Pahsa, the president of the Armenian delegation, wrote a letter to French Minister of Foreign Affairs and mentioned that 250,000 Armenians to Caucasia and 40,000 Armenians to Iran had been sent into exile. The numbers were exactly the same with the numbers in the Ottoman archives. [Numbers do not add up to even 1.4 million, let alone the 2.5 million that the Armenian Patriarchate had counted before the genocide].
