# Six Vilayets

The Six Vilayets (Ottoman Turkish: ولايت سته, Vilâyat-ı Sitte), the Six Provinces, or the Six Armenian Vilayets (Armenian: Վեց Հայկական Վիլայեթները Vets' haykakan vilayet'nery; Turkish: Altı vilayet, Altı il) were the main Armenian-populated vilayets ("provinces") of the Ottoman Empire. These were Van, Erzurum, Mamuret-ul-Aziz, Bitlis, Diyarbekir and Sivas.

## Name

The term Six Armenian Vilayets was a diplomatic usage referring to the Ottoman provinces with substantial Armenian populations. In fact, this term was known in the diplomatic language of the time as the area for which a number of Great Powers wished reforms for the benefit of the Armenians. The term was based on the official language adopted by the signatories of the Treaty of Berlin, the final act of the Congress of Berlin in 1878, in Article LXI: “The Sublime Porte undertakes to carry out, without further delay, the improvements and reforms demanded by local requirements in the provinces inhabited by the Armenians, and to guarantee their security against the Circassians and Kurds.”

#### Ottoman official population statistics, 1914

Note: The Ottoman population statistics doesn't give information for separate Muslim ethnic groups such as the Turks, Kurds, Circassians, etc.
The official Ottoman population statistics of 1914 that were based on an earlier census underestimated the number of ethnic minorities, including the number of Armenians. The Ottoman figures didn't define any ethnic groups, only religious ones. So the “Armenian” population as counted by the authorities only tallied ethnic Armenians who were also adherents of the Armenian Apostolic Church. Ethnic Armenians who professed the Muslim faith, which by that time had grown in number, were counted only as “Muslims” (not as Armenian Muslims or Armenians), while Armenian Protestants, just as Pontic Greeks, Caucasus Greeks, and Laz, were counted as "others".
