The imperial powers of the time sponsored archaeological expeditions to Central Asia, including Britain, France, Germany, Russia and Japan.
[3] Unknown to Macartney, Islam Akhun's partner, Ibrahim Mullah, was also selling similar items to the Russian consul Nikolai Petrovsky.
Although he could identify some as in Brāhmī script, in his first report on these collections, he wrote of others that they were: ...written in characters which are either quite unknown to me, or with which I am too imperfectly acquainted to attempt a ready reading in the scanty leisure that my regular official duties allow me ... My hope is that among those of my fellow-labourers who have made the languages of Central Asia their speciality, there may be some who may be able to recognize and identify the characters and language of these curious documents.
[7] He gave an extensive account and divided them into nine different groups based on the kind of scripts in which they were written, which resembled Kharosthi, Indian and Central Asian Brahmi, Tibetan, Uighur, Persian and Chinese.
Hoernlé discussed this issue in his 1899 report but decided in favour of their authenticity, recounting Islam Akhun's tale of the discovery of the manuscripts and documents in the ruined sites of the ancient Kingdom of Khotan in the Taklamakan Desert.
During his first Central Asia expedition in 1900 Stein visited ancient sites of Khotan, but although he excavated many manuscripts, he found nothing similar to those sold by Islam Akhun.
Initially Islam Akhun claimed innocence, insisting he had only been an agent for Macartney, and had himself purchased the documents from other parties, knowing how much the English desired them.
In the early summer of 1898, Islam Akhun acted as an unwilling guide for the explorer Captain Deasy on an expedition to look for ancient sites near Guma.
On his return, he forged a note in Deasy's handwriting to get money from Badruddin, the Aqsaqal (official who looked after the interests of the Indian traders, reporting to the Consul-General in Kashgar).
[17] Stein also reports various other dubious activities, including masquerading as a British agent searching for illegal slaves in order to blackmail locals.
