Muhammad Amin Bahadur Khan

In December 1846, emissaries of the Khan headed to Orenburg, a Russian border city, and from there to the capital Saint Petersburg, where they arrived on 19 March 1847.

The two envoys of the Khan demanded the demolition of the Raim fort (ru) built by the Russians near the mouth of the Syr-Darya River into the Aral Sea.

[2] In 1855, Muhammad Amin led an expedition to the Sarahs oasis against the Turkmen Teke tribe to conquer present-day southern Turkmenistan.

The Teke asked support from the Persian governor of Mashhad, Feridun Mirza, who sent 7,000 men from the citadel of Derbent and another 3,000 from Khorasan with 10 cannons.

Kalta Minor was originally intended to be the tallest minaret in the world, but with the death of Mohammad Amin Khan, the unfinished construction was stopped.
