History of Samara Oblast

The territory of the present Samara region became part of the Russian state in the middle of the 16th century, after the Kazan and Astrakhan khanates were conquered by the Russian state. In the 17th-18th centuries, the territory around the middle Volga was colonized by migrants from other regions of Russia and foreigners (in particular, the Volga Germans).

The intensified colonization of the region began only in the second half of the 18th century. From the mid 19th century, this region experienced economic growth. Samara became an important center of the Russian domestic grain market, which led to the development of trade and industry in the city. In 1851, Samara became the center of Samara guberniya (province).

In 1935, Samara was renamed into Kuybyshev (the historical name was returned in 1990). In Soviet times, industrialization had a serious impact on the development of the region. Construction of plants producing explosives, poisonous substances and ammunition began in the town of Chapayevsk.

During the Second World War, the region became one of the centers of the defense industry of the USSR. In 1941, an oil processing plant was put into operation in Syzran providing the army with fuel. Several aviation plants were evacuated to Kuybyshev from Moscow and Voronezh. They started production of “Il-2” attack aircraft.

More Historical Facts…

In 1942, a railway passed through Syzran to supply Soviet troops during the Stalingrad Battle. In 1941-1943, diplomatic missions of foreign countries to the USSR were located in Kuybyshev (Samara). In 1941, there were plans for transferring the capital of the country to Kuybyshev in case the German troops capture Moscow.

In the 1950s-1960s, this region was one of the leading centers of oil extracting in the USSR. In 1945-1951, Kuybyshev and Novokuybyshev oil processing plants were built. At the same time, construction of Zhiguli hydroelectric power station was resumed. It was put into operation in 1955. Because of this construction, the town of Stavropol was flooded and was rebuilt in a new place and received a new name - Tolyatti.

Later, the construction base created during the construction of Zhiguli hydroelectric power station was used to create a series of other large industrial enterprises in Tolyatti - “KuybyshevAzot” mineral fertilizer plant, “Tolyattikauchuk” synthetic rubber plant (1964-1966), the Volga Automobile Plant (1970), and the largest in the country and the world manufacturer of ammonia “TolyattiAzot” (1979).

At the same time, aviation production was expanded. Kuibyshev Aviation Plant began production of the most mass Soviet passenger medium-haul aircraft Tu-154. The Soviet rocket space program orders were also fulfilled at this plant (“Progress” rockets).

In the post Soviet period, due to saved economic potential, Samara oblast has become one of the main economic centers of the country.

Military intelligence: Railway bridge blown up in Russia's Samara Oblast

A railway bridge across the Chapayevka River in Russia's Samara Oblast has been blown up, paralyzing the traffic, Ukraine's military intelligence (HUR) said on March 4 without specifying who was responsible for the incident.

The bridge and the adjacent railway connection were used by Russia to transport military cargo, namely engineering explosives produced by the JSC Polimer in the city of Chapayevsk, the military intelligence agency said.

The agency's statement came after Russian Telegram channels reported the incident, publishing alleged photos of the bridge. According to military intelligence, the bridge was damaged at about 6 a.m. local time.

"Given the nature of the damage to the railway bridge, its use will be impossible for a long time," the agency said on its Telegram channel.

This is not the first such incident to take place in Russia in the past months.

In late January, military intelligence claimed that partisans burned down several relay cabinets on the railroad and other facilities in three regions of Russia that were reportedly used for the Russian troops' logistics.
