Hidden Armenians (Turkish: Gizli Ermeniler) or crypto-Armenians (Armenian: ծպտեալ հայեր tsptyal hayer; Turkish: Kripto Ermeniler) is an umbrella term to describe people in Turkey "of full or partial ethnic Armenian origin who generally conceal their Armenian identity from wider Turkish society." They are mostly descendants of Armenians in Turkey who were Islamized "under the threat of physical extermination" during the Armenian Genocide.
Turkish journalist Erhan Başyurt describes hidden Armenians as "families (and in some cases, entire villages or neighbourhoods) [...] who converted to Islam to escape the deportations and death marches [of 1915], but continued their hidden lives as Armenians, marrying among themselves and, in some cases, clandestinely reverting to Christianity." According to the European Commission 2012 report on Turkey, a "number of crypto-Armenians have started to use their original names and religion."The Economist suggests that the number of Turks who reveal their Armenian background is growing.
The western parts of the Armenian Highlands, the traditional homeland of the Armenian people, came under Ottoman (Turkish) control in the 16th century. Armenians remained an overwhelming majority of the area's population until the 17th century, however, their number gradually decreased and by the early 20th century they constituted up to 38% of the population of Western Armenia, designed at the time as the Six vilayets. Turks and Kurds made up a significant part of the population.
