In August 1955, the settlement of Pismyanka which was then part of the Tatar Autonomous Soviet Socialist Republic, was redesignated as a city and named Leninogorsk in honor of the revolutionary Vladimir Lenin.

As the geographer Yevgeny Pospelov states, the common toponym Pismyanka comes from the Russian adaptation of the Tatar Pismen or Pichmen, which is often found in the names of rivers and villages in Tatarstan.

The visual design of the coat of arms includes a black joist bordered with silver piercing into the green field, and there are two golden flowers tilting in opposite directions at the bottom of the shield.

[5][6] According to official guidelines, the green field with flowers symbolize the geographical features of the southeast of Tatarstan, and indicate a variety of the local flora and fauna.

Experts interpret the black joist in different ways: on the one hand, it might be considered as an oil gusher showing the economic prosperity of the area.

On the other hand, the shape of the joist can be interpreted as a network of roads and in Leninogorsk as an important industrial and transport hub in the south-east of the republic.

[8] The Leninogorsky district has the largest number of springs in the republic at 263, and large deposits of oil, bitumen, limestone, dolomite, sand and gravel, clay and other mineral resources.

In 1708 these territories became part of the newly formed Kazan province, which included all the middle and lower Volga and Ural regions.

The borders of the Kazan and Orenburg provinces passed along the Cheremshan River, then descended southeast to Kichuya before ascending northeast to Menzelinsk.

In the 1740s, settlers began to move to the lands of the modern Leninogorsk region as a result of the Russification policy pursued by the tsarist government.

According to the results of the population census in tsarist Russia carried out in the period from 1744 to 1747, there were only 13 villages in the region (Karataevo, Naderevo, Seitovo, Urmushla, Sary Bikchurovo, Analokovo, Ishtiryak, Karkali, Shugurovo, Toktarovo, Kuakbashevo, Shachili and Izmailovo).

In October 1773, a riot engulfed Bugulminskoe Vojvodstvo and a total of ten insurgent detachments of about 15 thousand people, armed with 15 cannons occupied the region.

The villages of Bakirovo, Novy Ishtiryak, Timyashevo, Upper Shirshila, Yultimirovo were subsequently founded as a consequence of this new wave of settlement.

On the basis of these reforms in 1781, the Bugulminsky uyezd was formed which included the territories of modern Leninogorsky, Almetyevsky, Cheremshansky and other districts.

Following the Stolypin reforms, a number of new villages had emerged on the territory of the district by 1905, for example, Novo-Elhovo, Akkul, Novaya Chershila, Maryanovka, Malakhovka, Volzhanka and Stepnoy Zai.

Leninogorsk was one of the battlefields of the Russian Civil War, and the town changed hands several times between the belligerents.

In October 1918, the Red Army occupied Bugulma, but the next spring the Bolsheviks were pushed back by White military leader Alexander Kolchak.

In the Bugulminsky canton alone, more than 35 thousand residents died of hunger, including a third of the population of the future Leninogorsky district.

In the early 1930s, therapeutic mud was discovered in the village of Bakirovo and a resort of the same name was built, and hospitals and first-aid posts began to open on the territory including the Nizhne-Cherchelinskaya outpatient clinic.

[19] In February 1935, the Novopismyansky district was formed, which included the Novo-Pismyansky, Staro-Pismyansky, Zai-Karataevsky, Glazovsky, Mikhailovsky, Ivanovsky, Alyoshkinsky and Gorkinsky village councils.

It has been established that 6,789 soldiers from the Leninogorsk region perished in the war, with 12 of them being awarded honors as Heroes of the Soviet Union — Gilmi Bagautdinov Gilmi, Gazinur Gafiatullin, Ivan Denisov, Ivan Zavarykin, Ibragim Murzin, Samat Sadriev, Grigory Ushpolis, Akram, Islam Khalikov, Misbakh Khaliulin, Evstafiy Yakovlev and Vasily Yanitsky, three more received the title of full holders of the Order of Glory – Gabdulla Matygullin, Mikhail Alaev and Yakov Nikolaev.

On August 18, 1955, by the decree of the Presidium of the Supreme Soviet of the RSFSR, the working settlement Novaya Pismyanka was transformed into a city and received the name of the leader of the revolution — Leninogorsk.

Many enterprises work only in the field of construction of facilities for the oil and gas industry, including Orteks, Uralstroyneft, RosNeftKompleks and other companies.

The presence of secondary specialized and higher educational institutions, as well as the city's significant share of the working population in the district, determines the human resources potential of Leninogorsk.

[30][31] The Leninogorsk district occupies an advantageous geographical position and is located close to important transport networks.

[35][36] In 2020, the Honored Doctor of the Republic of Tatarstan Rim Amerov was appointed to the post of head physician of the Leninogorsk CDH.

In November of the same year, additional hospital beds for patients infected by the coronavirus and pneumonia were funded for the Leninogorsk medical unit.

For instance, the specialists of the “Administration for Youth, Sports and Tourism” organize the Spartakiad among enterprises and educational institutions.

In February 2020, a carting competition was held in Leninogorsk, timed to coincide with the 100th anniversary of the formation of the Tatar ASSR.

[42] В феврале 2020-го к Лениногорске прошли соревнования по картингу, приуроченные к 100-летию образования ТАССР и 60-летию ДОСААФ Лениногорска[43] At different times in Leninogorsk and surrounding areas lived the educator Gabdrakhim Utyz Imyani, the orientalist Riza Fakhretdin, contemporary writers Shamil Bikchurin, Zyamit Rakhimov and other outstanding figures of culture and art.
