It is claimed that Merv was briefly
the largest city in the world in the 12th century.

Merv in modern Turkmenistan was the biggest city in the 12th century and the Mongols killed all the inhabitans of the biggest city in the 12th century. I also don't think that they killed 80% of Irans population but I can't see that it is wrong to claim that they killed 80% of the population of the Khwarazmian dynasty.
In 1221, Merv opened its gates to
Tolui, son of
Genghis Khan, chief of the
Mongols, on which occasion most of the inhabitants are said to have been butchered. The
Persian historian
Juvayni, writing a generation after the destruction of Merv, wrote
“The Mongols ordered that, apart from four hundred artisans. .., the whole population, including the women and children, should be killed, and no one, whether woman or man, be spared. To each [Mongol soldier] was allotted the execution of three or four hundred Persians. So many had been killed by nightfall that the mountains became hillocks, and the plain was soaked with the blood of the mighty.”
Oh and Urgench in modern Turkmenistan was also one of the biggest cities in the world and it experienced the same fate as Merv
In 1221,
Genghis Khan destroyed the city in the
Mongol invasion of Central Asia, in what is considered to be one of the
bloodiest massacres in human history. Despite the devastating effects of the invasion, the city was revived and it regained its previous status, being described by the 14th-century Arabic traveller
Ibn Battuta as "the largest, most considerable, most beautiful and majestic city of the Turks, with fine bazaars, wide streets, numerous buildings and impressive views".
