Ascension to the throne

After the death of Shaybanid ruler Abdulaziz Khan, a struggle for the throne ensued. Abdullatif Khan, who ruled in Samarkand, placed two grandsons of Shaybani Khan – Yar-Muhammad Sultan and Burkhan Sultan – on the throne in Bukhara. However, following Abdullatif Khan’s death in 1551, Barak Khan, ruler of Tashkent, seized Samarkand and assumed power there under the name Navruz Ahmad Khan, proclaiming himself supreme Khan of the Uzbeks. Abdullah Sultan, from a cadet branch of the Shaybanids and then ruler of Kermine, opposed him with the support of his uncle, Pirmuhammad Khan, ruler of Balkh. After Navruz Ahmad's death in 1556, Pirmuhammad Khan was declared supreme ruler.

Struggle to unite the state

In 1557, with the support of Sufi sheikhs, Abdullah Sultan seized Bukhara and became its ruler. By 1561, he was confident enough to proclaim his father Iskandar – then ruler of Kermine and Miyankal – as the supreme Khan of all Uzbeks. Iskandar was a modest, non-militaristic man focused on religious practices, so he entrusted state affairs to his son Abdullah.

Abdullah aimed to unify the four Shaybanid domains – Bukhara, Samarkand, Tashkent, and Balkh – into a single state. This effort took decades and was only fully realized by 1582. He fought a long war with the sons of Navruz Ahmad – Baba Sultan and Darvish Bek – suffering many setbacks before eventually defeating them. He went on to subdue Fergana and captured Balkh in 1573 after a prolonged siege. By 1574, Shakhrisabz, Karshi, and Hisar were added to his domains. In 1576, he recaptured Samarkand and took Tashkent.

Abdullah Khan’s monetary reform

In several stages, Abdullah Khan II implemented monetary reform. To address the shortage of silver and coins, he began minting gold coins under his father’s rule and oversaw their high-quality production in Bukhara. His reforms aimed to adjust the exchange rate of silver coins in response to rising silver prices. When Iskandar Khan was still the nominal head (1560–1583), minting silver coins remained decentralized. Nevertheless, silver tangas were minted in Bukhara, Samarkand, Balkh, Tashkent, Andijan, Akhsikent, and Yassi (Turkestan) under his name.

In 1583, Abdullah Khan centralized silver coin production in Bukhara. He also introduced copper coins of varying denominations for daily urban trade. These reforms successfully ended the monetary crisis, stopped massive capital outflow, and supported all types of commerce – transit, intercity, and local trade.
