The Soviet period
On June 17, 1917, the Provisional Government allocated the southern part of Tomsk province to Altai with the center in Barnaul. A temporary provincial executive committee was formed here, along with which the Soviets acted with the support of the Barnaul garrison.
On December 7, 1917, the Bolsheviks took power in Barnaul. Under the threat of a military clash with the Czechoslovak corps, the Military Revolutionary Committee, headed by Ivan Prisyagin, decided to leave Barnaul.. The Soviet government returned to the city only on December 9-11, 1919, together with the regular Red Army and the partisan army led by Efim Mamontov. The White Guards left the city in the hope of reaching Novonikolaevsk (Novosibirsk). Retreating, the white army in the area of the village of Talmenka fell into an ambush prepared by the First Chumysh Soviet Partisan Division led by M. Vorozhtsov (Anatoly).
After the civil war, the city began to change, many citizens began to acquire vegetable gardens, cattle, engaged in handicrafts, collective farms appeared in the city.
Industrialization and collectivization greatly influenced the development of the city. Residents of villages and small towns move to the city, and the city itself, in fact, becomes the center of the agro-industrial complex of the region. In 1923, the city's central power plant came into operation. And in 1926, by decision of the City Council, the Barnaul pond was lowered. In 1929, a city radio center appeared in Barnaul. The first bus line "Bazar — Vokzal" has been opened. And in 1933, the first higher educational institution in the city was organized — the Teachers' Institute (Barnaul State Pedagogical Institute).
In 1932, the largest melange plant in Western Siberia was founded, and in parallel with it, the construction of the Sotsgorodka complex, unprecedented before in the city, was underway — residential buildings, kindergartens, schools, medical institutions for those who worked at this enterprise.
Due to the formation of the Altai Territory in 1937, Barnaul was given the status of its administrative center.
According to the general project for the development of the city from 1937, the main thoroughfares were to be Leninsky Prospekt and 2-3 Altai Streets, united by a green strip of squares. Around the central square, at the intersection of these streets, buildings of 5-6 floors were designed for administrative and economic institutions, a bank, and the NKVD. The city council building was supposed to be built in the center of the square, moving it towards the Ob River. In front of him is a space for demonstrations and rallies, then a square with parterre greenery and an obelisk. In the same project, the idea of the Ob Boulevard was first laid. However, the war made its own adjustments — the central square was never formed, and the main streets remained with wooden buildings.
During the Great Patriotic War, about a hundred industrial enterprises from Moscow, Leningrad, Odessa, Kharkov, and other cities temporarily occupied by nazi troops were permanently located in the city. They became the basis of the city's industry (they were not returned back). Large machine—building enterprises began to work in the city - Transmash plants, boiler house, machine tool building, the radio factory produced its first products. The city supplied the front with tank diesel engines, oxygen-breathing equipment for pilots, uniforms, sheepskin coats, felt boots. According to some reports, about half of the cartridges used by the Soviet Army during the war were produced in Barnaul at a machine tool factory.
The post-war years were marked by the rapid development of the chemical industry. In the 50s and 60s, chemical fiber factories, tire factories, asbestos products, and a number of others were built. For the first time, an attempt was made to solve the housing problem and relocate Barnaul residents from dilapidated wooden houses to relatively well-maintained "five-story buildings". This is how areas of mass, "in—line" development appeared - a stream, followed by Cheryomushki, a Sunny glade, and a Harvest.
In 1980, by Decree of the Presidium of the Supreme Soviet of the USSR, the city was awarded the Order of the October Revolution.
