Geographical trace of the Yenisei Expedition of 1905: historical and modern significance

The little-known Yenisei Expedition of 1905 led by I.S. Sergeyev, K.V. Ivanov, and I.I. Islyamov is examined and described. Based on the study of archival documents, the preparation of the expedition in the highest state institutions of the Russian Empire and the specific circumstances of its journey from European seaports to the Russian river port in Yeniseisk are demonstrated. The significance of the expedition is analyzed in connection with its contemporary realities. An assessment of the importance of the waterway along the Yenisei River is also provided, which connects not only the South and North but also the West and East of Russia. The special role of certain participants, particularly I.I. Islyamov, who played a notable role in the geographical exploration of Russia but remained little-known to the general public and even many specialists, is emphasized.
