[2] Shaykh Haydar, a leader of the militaristic Safaviyya Sufi movement, was killed in a battle in Tabasaran in the year 1460, and only his severed head was buried in Tabriz.
[2] However, an inscription found during an archeological investigation dates the construction of the tomb to the final years of the reign of the Ilkhani ruler, Abu Sa'id Bahadur Khan.
[3][2] Later in the early 16th century, Shaykh Haydar's son, Shah Ismail, transferred his remains to Ardabil, and entombed them in the Sheikh Safi al-Din Khānegāh and Shrine Ensemble.
Tiling works were completed during the Safavid period, while the building was restored in the modern era and there is now a mosque, as well as several houses and facilities built around it.
Decorative calligraphy on the outside of the mausoleum, dating back to the Safavid period and using tiles, reveals the words Jalal-Allah and an inscribed version of the Al-Fatiha.
