The ruins of the Tangut city Khara-Khoto were brought to light by Pyotr Kozlov, who recovered over 2,000 books from the site. This discovery, made during his 1907–1909 expedition, remains a primary contribution to the historical understanding of the region. His career spanned service as a major general and exhaustive scientific work in geography and archaeology.
Early Expeditions and Command
Born in 1863 in Dukhovshchina, Kozlov pursued an exploration career rather than the military path intended by his parents. He began by working with Nikolai Przhevalsky before serving under Pevtsov and Roborovsky. Following Roborovsky's illness in 1895, Kozlov assumed general command. Between 1899 and 1901, he explored the upper reaches of the Yangtze, Mekong, and Yellow rivers, receiving the Constantin Medal in 1902 for his geographical documentation.

During the early 20th century, Kozlov conducted research that drew the attention of British officials including George Macartney. His 1905 meeting with the Dalai Lama in Urga caused political alarm regarding potential Russian influence. His later excavation of Khara-Khoto, a city destroyed in 1372, earned him the 1911 Founder’s Medal from the Royal Geographical Society. These findings were detailed in his 1923 book, Mongolia and Amdo and the Dead City of Khara-Khoto.
Final Research and Retirement
Kozlov led his final expedition to Mongolia and Tibet between 1923 and 1926. This journey resulted in the uncovering of royal Xiongnu burials at Noin-Ula and the recovery of Bactrian textiles. He was accompanied by his wife, Elizabeth Kozlova, who served as the expedition's ornithologist. Following these efforts, he retired to a village near Novgorod and eventually passed away in 1935 in Peterhof, where he was interred at the Smolensky Lutheran Cemetery.
