Forty years prior to his 1933 North West China Scientific Expedition, a young Sven Hedin accepted the invitation of the Czar of Russia to lead a convoy to Lhasa and Kashgar in 1893. He led three such expeditions between 1893 - 1908. On the first expedition, he left Stockholm on 16 October 1893, for the Pamir Mountains traveling via Saint Petersburg and Tashkent. During this expedition, he remained in Kashgar until April, 1895, from where he crossed the Taklamakan to the Khota River. Returning from a stopover in Kashgar in January 1986, he continued to travel extensively in Central Asia, finally crossing Northern Tibet and China in late June, and eventually arriving in Peking on 2 March 1897.
