Ligdan Khan
After suppressing the rebellion of the right three tumens in Mongolia, Dayan Khan exempted his soldiers, who participated the battle of Dalan-Terqin, from imposts and made them Darkhan in 1513. Even after the collapse of Northern Yuan dynasty with the death of Ligdan Khan in 1635, the title of darkhan continued to be bestowed on religious dignitaries, sometimes on persons of low birth. For example, in 1665, Erinchin Lobsang Tayiji, the Altan Khan of the Khalkha, bestowed the title on a Russian interpreter and requested the Tsar of Russia to exempt the interpreter from all tax obligations.
