Farrukh Yassar was the last independent Shirvanshah of Shirvan (1465–1500). In 1500, the first Safavid ruler, Ismail I, decisively defeated and killed Farrukh Yassar during his conquest of the area. Descendants of Farrukh Yassar continued to rule Shirvan under Safavid suzerainty, until 1538, when Ismail's son and successor Tahmasp I (r. 1524-1576) appointed its first Safavid governor, and made it a fully functioning Safavid province.

He averted strategy of his ancestor's - alliance with Timurids, instead he moved towards Uzun Hasan. He married his daughter to Uzun Hasan's son Sultan Yagub. On 31 January 1468 the combined forces of Shirvanshahs and Ak Koyunlu defeated Timurid khan Abu Sa'id Mirza. Future sultans of Ak Koyunlu - Baysonqor and Murad were his grandsons.

He sent his "Khalaf ul umarah and akabir" (Deputy of emirs and nobles) Ziyaaddin Yusif and his personal merchant Khawja Yar Ahmad with 2 bullions of gold to Istanbul, in order to establish relations with Mehmet the Conqueror.

In 1465, Shirvanshah envoy Hasan Shirvani was sent to Moscow in order to establish diplomatic relations, in response Ivan III of Russia sent an embassy with leadership of Vasily Papin and a group of merchants (which also included Afanasy Nikitin) for trade and a pact against Golden Horde.

During Uzun Hasan's reign, relations with Safavids were quite peaceful. But, in 1488 Shaykh Haydar of Safaviyya extremist Shia sect moved through Shirvan towards Derbent, supposedly to wage jihad against Circassians, but instead laid siege to Shamakhy. He captured the capital and burned it. Farrukh Yassar was not able to mount defense and asked his son-in-law Sultan Yagub of Ak Koyunlu to come to his rescue on 9 June 1488. Upon hearing his arrival, Sheikh retreated to Derbent. Combined forces of Ak Koyunlu under Suleiman bey and Shirvanshah forces which were led by shah himself, attacked to Qizilbash on 9 July 1488. Their combined forces were able to defeat the Safavid Qizilbash forces and were Shaykh Haydar was wounded by an arrow. He was captured by gatekeeper Ali aga who severed his head and sent to Sultan Yagub.
