The history of Omsk is a compelling story of a military outpost on the southern borders of Siberia transforming into one of the region's largest cities. Its history began in 1716, when, by decree of Peter the Great, an expedition led by Lieutenant Colonel Ivan Buchholz founded the first wooden fortress at the confluence of the Irtysh and Om rivers. The main task of the Omsk fortress was the protection of borders and the further development of Siberian lands. Initially, it was a purely military settlement, but its strategic position fostered rapid growth, and by 1782, Omsk officially received city status.
In the 19th century, the city's role changed radically. From a military fortress, it turned into a vital administrative centre. A key event was the transfer of the Main Administration of Western Siberia from Tobolsk to Omsk in 1839. This made the city the de facto capital of a vast region covering Western Siberia and the northern territories of modern-day Kazakhstan. Omsk became the residence of the Governor-General and the decision-making centre for all of Siberia.
A new powerful impulse for the city's development was provided by the construction of the Trans-Siberian Railway, which reached Omsk in 1894. Its advantageous geographical position at the intersection of the railway and the navigable Irtysh River turned it into a major transport hub and a centre for wholesale trade. Grain, the famous Siberian butter, and other agricultural products were shipped from here across the country and abroad. The economic boom was also facilitated by the Stolypin agrarian reform, which caused a mass migration of peasants to the region.
By the beginning of the 20th century, Omsk had become a prosperous and the most populous city in Siberia. Its appearance changed rapidly: multi-storey stone buildings in the classical style replaced wooden structures. Industry developed actively, and branches of Russian and foreign banks, as well as trade missions, opened. Cultural life did not lag behind: the city had a men's gymnasium, a teachers' seminary, a theatre, and a museum under the West Siberian Department of the Imperial Russian Geographical Society, which made a huge contribution to the study of the region.
