[1] According to historical evidence such as the accounts of Arakel of Tabriz, Melik Haykazyan, the first dynastic ruler of the melikdoms of Aghahech-Kashatagh (1450–1520), made Kashataghk his capital.

[3][4] The Melik Haykaz Palace was built at the end of the 15th century on an artificial slope surrounded by a fortified wall with towers and gates.

[6] According to historian Morus Hasratyan, Haykaz II lived in exile in Iran for 10–15 years due to the Ottoman Empire's brutal policies during the temporary occupation of Transcaucasia in the 1580s or 90s.

After the reconquest of the region by Iran in 1606–1607, Haykaz II, as one of the loyal supporters of the Shah, was not only restored to his rights but also received some possessions beyond its borders.

It includes the joint appeal of Melik Hakhnazar and his subordinate village headmen (Armenian: tanuter, Persian: kadkhudā), addressed to the shah's court.

In the document, they appoint as their authorized representatives the son of Melik Hakhnazar, Ilyas (Elias), and one of the elders, Gikor, who were supposed to present the problems arising in the region to the shah's court and defend the interests of the local population.

[6] The names of Melik Hakhnazar and his brother Haykaz (who is also mentioned in the document of 1691/92 as one of the witnesses) are marked in the inscription of 1682 on the facade of the entrance to the Church of the Holy Virgin in the village of Mirik of the Kashatagh region.
