Shirvanshah in the context of "Safavid conquest of Shirvan"

Derbent, also historically known as Darband, or Derbend, is the southernmost city in Russia. It is situated along the southeastern coast of the Republic of Dagestan, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains, and connecting the Eurasian Steppe to the north and the Iranian Plateau to the south. Derbent covers an area of 69.63 square kilometres (26.88 sq mi) with a population of roughly 120,000 residents.

Derbent is considered the oldest city in Russia, with historical documentation dating to the 8th century BC, making it one of the oldest continuously inhabited cities in the world. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, and Shirvan kingdoms. In the early 19th century, the city came under control of the Russian Empire through the Treaty of Gulistan signed with Qajar Iran.

The Palace of the Shirvanshahs (Azerbaijani: Şirvanşahlar Sarayı, Persian: کاخ شروان‌شاهان) is a 15th-century palace built by the Shirvanshahs and described by UNESCO as "one of the pearls of Azerbaijan's architecture". It is located in the Inner City of Baku, Azerbaijan and, together with the Maiden Tower, forms an ensemble of historic monuments inscribed under the UNESCO World Heritage List of Historical Monuments. The complex contains the main building of the palace, Divanhane, the burial-vaults, the shah's mosque with a minaret, Seyid Yahya Bakuvi's mausoleum (the so-called "mausoleum of the dervish"), south of the palace, a portal in the east, Murad's gate, a reservoir and the remnants of a bath house. Earlier, there was an ancient mosque, next to the mausoleum. There is still ruins of the bath to the west of the tomb.

In the past, the palace was surrounded by a wall with towers and, thus, served as the inner stronghold of the Baku fortress. Despite the fact that at the present time no traces of this wall have survived on the surface, as late as the 1920s, the remains of apparently the foundations of the tower and the part of the wall connected with it could be distinguished on the north-eastern side of the palace.

The Bibi-Heybat Mosque (Azerbaijani: Bibiheybət məscidi) is located in the village of Bibiheybət, near Baku, Azerbaijan. The current structure, completed in the 1990s, replicates the original 13th-century mosque built at the behest of Shirvanshah Farrukhzad II Ibn Ahsitan II. The historic mosque was completely destroyed by the Bolsheviks in 1936.

It is occasionally called "the Mosque of Fatima", which is how Alexandre Dumas referred to it during his visit in the 1850s.

Shaykh Haydar or Sheikh Haydar (Persian: شیخ حیدر Shaikh Ḥaidar; 1459–9 July 1488) was the successor of his father (Shaykh Junayd) as leader of the Safavid order from 1460 to 1488. Haydar maintained the policies and political ambitions initiated by his father. Under Sheikh Haydar, the order became crystallized as a political movement with an increasingly extremist heterodox Twelver Shi'i coloring and Haydar was viewed as a divine figure by his followers. Shaykh Haydar was responsible for instructing his followers to adopt the scarlet headgear of 12 gores commemorating The Twelve Imams, which led to them being designated by the Turkish term Qizilbash "Red Head".

Haydar soon came into conflict with the Shirvanshahs, as well as the Ak Koyunlu, who were allied to the former. Following several campaigns into the North Caucasus, mainly in Circassia and Dagestan, he and his men were eventually trapped in 1488 at Tabasaran by the combined forces of the Shirvanshah Farrukh Yassar and Ya'qub Beg of the Ak Koyunlu. In a pitched battled that ensued, Shaykh Haydar and his men were defeated and killed. He was succeeded by his son Soltan-Ali as leader of the order. Soltan-Ali was on his part succeeded by Haydar's younger son, who would become the founder of the Safavid dynasty, and known by his regnal name of Ismail I.
