Irkutsk Oblast

Climate

The climate varies from warm summer continental in the south to continental-subarctic in the northern part (Köppen climate classification: Dwc). For almost half the year, from mid-October until the beginning of April, the average temperature is below 0 °C (32 °F).^[10] Winters are very cold, with average high temperatures in Irkutsk of −14.9 °C (5.2 °F) and average lows of −25.3 °C (−13.5 °F) in January. Summers are warm but short: the average high in July is +24.5 °C (76.1 °F) and the average low is +11.2 °C (52.2 °F). However, by September, the weather cools down significantly to an average daily high of +15.3 °C (59.5 °F) and an average daily low of +2.5 °C (36.5 °F).^[11][12] More than half of all precipitation falls in the summer months, with the wettest month being July, with 96.2 millimeters (3.79 in) of rain. January is the driest month, with only 11 millimeters (0.43 in) of precipitation. Annual precipitation averages 419.8 millimeters (16.53 in).^[13]

Ancient and early medieval history

The territory of present-day Irkutsk Oblast has been inhabited since the Upper Paleolithic. Among its best-known archaeological sites are Mal'ta and Buret', situated in the upper Angara basin. Excavations at these sites uncovered dwellings, tools made from stone and bone, ornaments, burials, and figurative art dating from the last Ice Age.^[14]

During the Mesolithic, Neolithic and Bronze Age, the Cis-Baikal region supported successive communities of hunter-gatherers and fishers. Archaeologists distinguish several cultural and mortuary traditions, including the Kitoi, Isakovo, Serovo and Glazkovo complexes. Important burial grounds have been excavated along the Angara, on the western shore of Lake Baikal, and in the Olkhon area. Archaeological evidence indicates long-term human occupation, although the degree of continuity between these cultural complexes remains debated.^[15][16]

From the late first millennium BC onward, the southern Baikal region formed part of the wider political and cultural world of the eastern Eurasian steppe. At different periods, communities around Lake Baikal interacted with, paid tribute to, or came under the influence of the Xiongnu, Xianbei, Rouran, Türk, Uyghur, and Yenisei Kyrgyz states. Their authority was not necessarily continuous or uniform across the whole territory of the modern oblast, particularly in the northern forest and taiga zones.^[17]

Between approximately the sixth and tenth centuries, written sources mention the Kurykans in the Lake Baikal region. They appear in Chinese accounts and in the Orkhon inscriptions as the "Three Kurykans". Archaeologists have frequently associated them with the Kurumchi cultural tradition of the western Baikal, upper Angara and upper Lena regions, noted for fortified sites, animal husbandry, ironworking and distinctive burials.^[18][19]

Mongolic period

Medieval Mongol sources referred to the wider region around Lake Baikal as Bargujin-Tokum, which was inhabited by the Barguts, Khori-Tumats, Buryats and other forest peoples. In 1207, Jochi, the eldest son of Genghis Khan, led a campaign that brought the northern forest peoples into the Mongol Empire.^[20] After the fragmentation of the Mongol Empire, the Baikal region remained connected to the Northern Yuan and the wider Mongolic world. By the 16th and early 17th centuries, some communities were subject to or paid tribute to Khalkha and Oirat rulers. Western Cis-Baikal, however, was not administered as a unified part of a single Mongol khanate. Local Buryat uluses retained their own leaders, while the region was contested by the Khotogoit Altan Khans, the Oirats and northern Khalkha.^[21]

Russian expansion and colonization

Russian expansion into the region began in the early 17th century, when Cossack detachments advanced eastward from Yeniseysk into the Angara and upper Lena basins. Their principal objectives included control of the Siberian fur trade and the collection of yasak, a tribute generally paid in sable and other valuable furs, from Indigenous communities.^[22] The Russian state consolidated its presence through a chain of fortified settlements. Bratsk ostrog was established on the Angara in 1631, followed by other forts and winter stations, including Verkholensk in the upper Lena region, Balagansk in 1654 and Irkutsk in 1661. These settlements served as military and administrative centres for collecting tribute, controlling river routes and supporting further Russian settlement.^[23][24] The incorporation of the region was a prolonged and uneven process rather than a single peaceful act. Cossack detachments demanded yasak from Buryat, Evenk and other communities and sometimes took members of prominent families as amanats, or hostages, to guarantee payment and political submission. Some Buryat uluses resisted Russian expeditions, attacked forts or moved toward Mongolia and other parts of the Baikal region. Other leaders negotiated with Russian officials, entered tributary relations or sought Russian support in conflicts with neighbouring groups.^[25][26] By the end of the 17th century, most of the western Baikal and upper Angara region had been incorporated into the Russian state. Russian peasant, merchant and clerical settlement subsequently expanded around the forts and along the major rivers. Agricultural colonization and the allocation of land to settlers reduced Indigenous access to some pastures, hunting grounds and migration routes, contributing to further disputes and population movements.^[27] Russian rule nevertheless continued to rely partly on existing clan and territorial leaders. The incorporation of numerous Mongolic-speaking communities into a common administrative system also contributed over time to their consolidation under the broader ethnonym Buryat.^[28]

Imperial consolidation in the 18th century

During the 18th century, the military foothold established by Russian forts developed into a more permanent system of imperial administration, taxation and settlement. Indigenous communities continued to pay yasak, while the Russian authorities governed Buryat, Evenk and Tofalar territories partly through local clan and territorial leaders. The relationship between Indigenous communities and the state varied: local leaders petitioned officials, negotiated taxation and land use, and sought recognition of customary rights, while disputes over tribute, pasture and hunting grounds continued.^[29]

The Treaty of Kyakhta of 1727 formalized much of the frontier between the Russian and Qing empires south of the Baikal region and established regulated trade through Kyakhta. The new imperial border restricted earlier movements between communities around Lake Baikal and Mongolia, although commercial, religious and family connections continued across it.^[30]

Russian agricultural settlement expanded along the Angara, Lena and their tributaries. The appropriation of land for villages, monasteries and officials placed increasing pressure on some Indigenous pastures, hunting territories and seasonal routes. At the same time, Buryat communities adapted to the changing economy through combinations of pastoralism, hunting, fishing, agriculture and trade. Differences also developed between communities living near Russian settlements and those maintaining closer relations with Mongolia and the eastern Baikal region.^[31]

The Eparchy of Irkutsk was established in 1727 and became an important centre of Orthodox missionary activity in Eastern Siberia. Missionaries opened churches and schools and sought to convert Indigenous inhabitants, particularly western Buryats living close to Russian settlements. Conversion was gradual and uneven, and many communities combined Orthodox practices with earlier religious traditions.^[32]

Irkutsk as an administrative and commercial centre

As imperial control over Eastern Siberia became more firmly established, Irkutsk developed from a frontier fort into the principal administrative and commercial centre of the region. Its position on routes connecting European Russia with the Baikal region, Mongolia, China, Yakutia and the Pacific contributed to its growth. Trade through Kyakhta brought Chinese tea, silk and other goods into Siberia, while furs and Russian manufactures travelled in the opposite direction.^[33]

Irkutsk's administrative importance increased during the century. It became the centre of a separate province within the Siberia Governorate, and the re-established Irkutsk Governorate formally opened in 1765. Its jurisdiction at different times extended over much of Eastern Siberia, making the city a base for imperial administration, taxation, exploration and relations with neighbouring Asian states.^[34]

Irkutsk also served as a logistical centre for expeditions into northeastern Asia and the Pacific. Preparations for the First Kamchatka expedition and the Great Northern Expedition involved officials, supplies and transport routes based in Eastern Siberia. During the second half of the century, Irkutsk merchants became involved in the fur trade of the Aleutian Islands, the North Pacific and later Russian America. Among the most prominent was Grigory Shelikhov, whose commercial enterprises contributed to the creation of the Russian-American Company in 1799.

The growth of commerce and administration supported the development of crafts, schools and cultural institutions. A school attached to the Ascension Monastery opened in 1725, the Irkutsk Eparchy was founded in 1727, and a navigation school was established in the middle of the century. By the late 18th century, Irkutsk had a public library, a regional museum and an amateur theatre.^[35]

The city's built environment also changed. Among the notable stone buildings constructed during the century were the Church of the Saviour and the Church of the Exaltation of the Cross. Nevertheless, most inhabitants of the wider region continued to live in rural settlements, Indigenous uluses and dispersed hunting or pastoral territories rather than in Irkutsk itself.

19th century

In the late eighteenth century and the early nineteenth century, Irkutsk Province gradually increased in importance as a center of trade, craft, and culture. It became the center of Russian trade with China and, from the 1830s, a gold-manufacturing center of Eastern Siberia. In 1803 Irkutsk became the center of the Siberian Governorate-General, and in 1822 it became the center of the Eastern Siberian Governorate-General. The Governors-General of Eastern Siberia greatly influenced the development of the city.

Irkutsk merchants explored the Yeniseysky and Leno-Vitimsky gold regions and substantially increased their capital, which made them the richest merchants in Siberia. The Irkutsk merchant class began to play a major role in the city's development. Intensive city construction took place. Private residences, hospitals, orphanages, and schools were built, while significant funds went towards education and the development of science in the region.

The architecture of the city of Irkutsk underwent change. The Irkutsk White House [ru], done in Russian classic style in 1800–1804, and the Moscow Triumphal Gates of Irkutsk [ru] – a monument of the nineteenth century, were built in honor of the tenth anniversary of Alexander I's reign.

In the second half of the nineteenth century the printing art developed in Irkutsk, the first newspapers being, “Irkutsk province news” and “Amur”. The names of A.P.Schapov, M.B.Zagoskin, V.I.Vagin were connected with the newspaper “Siberia”. In 1851, the first scientific organization in Eastern Siberia – the Siberian branch of Russian geographical society, was opened. In 1877, it was called the Eastern-Siberian branch. V.I.Dybovskii, A.L.Chekanovskii, I.D.Cherskii, V.A.Obruchev, geologists, geographers and researchers of Siberia, worked in Irkutsk Oblast on exploring Lake Baikal and the Lena River.

The summer of 1879 could be considered to be a dramatic period in the city of Irkutsk's history. During a July 22–24 fire almost all the central parts of the city were burnt, and more than two thirds of city buildings and 75 city districts were destroyed. The city began to revive, getting a new look. Stone and wooden constructions built after the fire have been preserved up to the present day. In 1898 the arrival of the first train via the Trans-Siberian Railway to Irkutsk Oblast was a major event. The construction of the Trans-Siberian Railway contributed to further city development.

Several politically exiled figures were connected with Irkutsk city. Among the first of the exiled was A.N. Radischev, who lived in Irkutsk for more than 3 months. Since the 1830s, the Decembrists lived in settlements and in colonies in the Irkutsk Oblast. The exiled houses of Volkonsky and Trubetskoy later became house-museums. N. A. Panov, I. V. Podzhio, A. Z. Muravyov, P. A. Mukhanov, A. P. Yushnevsky, V. A. Bechasnov, the wife of Trubetskoy and their children stayed in Irkutsk for the rest of their lives. In the late 1850s, the Petrashevtzy appeared in Irkutsk. The exiled historian-democrat, A.P. Schapov, lived here until his last days, and the Polish rebels and revolutionaries (including the narodnik) also lived here.

A well-known Russian publicist of the nineteenth century, N. Shelgunov, wrote about Irkutsk: “Irkutsk is the only Siberian city, which has the city character. ...As England created London, France - Paris, Siberia – created Irkutsk. Siberia is proud of Irkutsk, “not to see this city” means “not to see Siberia”.

In the early nineteenth century the city was considerably changed, especially its center. Large buildings were being built, mason streets were being made, cab drivers and street lights appeared. The water supply and the first electrification stations were built. The Irkutsk Regional museum was stamped with the names of Siberian researchers on its walls (1883), the building of the first public community, city theater (1897), Kazan' cathedral, made in new Byzantine style (1893), and the Roman Catholic cathedral (1895) completed an architectural style of the city. In 1908 a monument to Alexander III was opened on the Angara embankment.

20th century

The city was damaged and influenced by the political events of the twentieth century – the Russian revolution, the 1917 October Revolution, the Civil war and the Great Patriotic War.

Since the 1930s the industrial construction of the city had begun. Mechanical engineering plants, the air plant, brick and concrete plants, tea fabric, and food industry plants were being built. Economic development of the city contributed to scientific, educational and cultural development. The first Higher education in Eastern Siberia, Irkutsk State University was founded in 1918. Its departments were developing as independent institutes: medical, pedagogical, finance-economical. In 1930 the metallurgic institute was opened, in 1934 the agricultural institute was organized.

The early Soviets educated women in traditional professions like nursing and primary education. At right is the Irkutsk orphanage named for E. Medvednikova, which served both as an eleemosynary institution and educational facility.

Since the 1950s a rapid development of the city of Irkutsk took place. In 1947 streetcar routes were opened in the city and trolleybus routes were opened in 1972. In 1958 a TV center was established. The city's larger districts and micro regions construction period began. New districts such as Baykalsky, Solnechny, Yubileyny, Primorsky, Akademgorodok and others were created.^[36]

Soviet era

During the Soviet period, the high authority in the oblast was shared between three persons: The first secretary of the Irkutsk CPSU Committee (who in reality had the biggest authority),^{[citation needed]} the chairman of the oblast Soviet (legislative power), and the chairman of the oblast Executive Committee (executive power). After the abolition of Article 6 of the Constitution of the USSR in March 1990, the CPSU lost its monopoly on power. The head of the Oblast administration, and eventually the governor was appointed/elected alongside elected regional parliament.

Russian Federation

The Charter of Irkutsk Oblast is the fundamental law of the region. The Legislative Assembly of Irkutsk Oblast is the province's standing legislative (representative) body. The Legislative Assembly exercises its authority by passing laws, resolutions, and other legal acts and by supervising the implementation and observance of the laws and other legal acts passed by it. The highest executive body is the Oblast Government, which includes territorial executive bodies such as district administrations, committees, and commissions that facilitate development and run the day to day matters of the province. The Oblast administration supports the activities of the Governor who is the highest official and acts as guarantor of the observance of the oblast Charter in accordance with the Constitution of Russia.

Religion

According to the 2012 Arena Atlas survey, 28.1% of the population of Irkutsk Oblast adhered to the Russian Orthodox Church, 5.7% belonged to other Orthodox churches or identified as Orthodox without belonging to a church, and 6.7% identified as other Christians. Muslims accounted for 1.2% of the population, while 2.2% followed pagan or other traditional religions. A further 37.2% described themselves as spiritual but not religious, 17.5% as atheist, and 1.4% followed other religions or did not answer the question.^[43] The survey presents results for the population of the oblast as a whole and does not provide a reliable separate religious breakdown for its ethnic communities. Among the Buryats of the western Baikal region, including those of the Ust-Orda Buryat Okrug, shamanism has traditionally had a particularly strong presence. Buddhism and Russian Orthodoxy are also practised by some Buryats, and religious affiliation does not always correspond to exclusive practice: ancestral rites, the veneration of sacred natural places and other shamanic traditions may coexist with Buddhism or Christianity.^[45]

Population

Irkutsk Oblast registered natural population growth in 2008, the first time after 1993.^[47] Still, the future prospects for population growth in Irkutsk seems bleak. In 2007, women in Irkutsk were having an average of 1.602 children each. Fertility rate was extremely low in urban areas, where women were having just 1.477 children each. In rural areas however, the fertility rate was slightly above replaceable levels. In rural areas of Irkutsk Oblast, women were having an average of 2.165 children each. (Figures are not available for 2008, although for Russia as a whole fertility rates for 2008 were approx. 6% higher than that in 2007, and for Irkutsk 9% higher).^[48]
