The main water artery is the Irtysh River and its tributaries the Ishim, Om, Osha, and Tara Rivers. The region is located in the West Siberian Plain, consisting of mostly flat terrain. In the south is the Ishim Plain, gradually turning into steppe, forest and swampy taiga to the north. The soil is sandy and silty. Along the Irtysh River, in t. N. Irtysh region, there is an "oasis" microclimate, with a wooded landscape and gullies. There, the most fertile land in the region can be found. The Omsk region contains many lakes, the largest of which are Tenis-Saltaim, Ik, Ebeyty, Ulzhay and Tobol-Kushly.

## History
### Prehistory and the Middle Ages

Archeological findings indicate that the present day territory of the oblast has been inhabited for the last 14,000 years. Neolithic societies in the area lived by fishing and hunting. About three thousand years ago, pastoralism began to take hold. Ust'-Ishim man, the remains of a man that lived 45,000 years ago, was discovered in Omsk Oblast.
Various Turkic states dominated the area throughout the Medieval era. The most notable of these were the Western Turkic Khaganate and the Siberian Khanate. Siberian Tatars, Mongols, Khanty and Mansi tribes, along with others, inhabited the territory.

### Exploration of Siberia

The Russian history of Omsk began with the 1584 arrival of a Cossack force under the command of ataman Yermak Timofeyevich, who defeated local rulers and established nominal Russian control of the area. To support further expansion tsars Feodor I and Boris Godunov initiated the construction of fortified settlements and military outposts in the south of Siberia in order to defend their subjects from raiding nomadic tribesmen and to exert authority over local populations, specifically over the tribute-paying Siberian Tatars of The Baraba Lands. The first permanent Russian settlement in the region, the city of Tara, was founded in 1594, soon it began to play an important part in fur trade that connected Russia with Central Asia and China.
In 1716 a fortress was constructed at the confluence of the Om and Irtysh rivers on the orders of sublieutenant Ivan Bugholtz. The fortress would form the nucleus for the development of the future city of Omsk. By the second half of the 18th century, Omsk fortress was the largest building of any kind in the eastern part of Russia.
As Russian settlements continued to spread through the Yenisei, Tobol and Irtysh watersheds in the course of the 18th century, so did the development of the Omsk and the surrounding region. In 1753 a customs post was established to tax goods brought into the city by the ever-increasing trade with Kazakh tribesmen. In 1764, when the Siberian provinces of Russia were organized into two governorates with centers in Irkutsk and Tobolsk, the city of Tara and the fortress of Omsk were assigned to the latter. In 1780, on the orders of Catherine the Great the fortress was transferred to Kolyvan Oblast. By this time Omsk had grown to the size of a small city, however, from 1797 to 1804 it did not possess its own uyezd.

### Russian Empire

In 1804, the territories surrounding Omsk were organized into the Omsk Okrug. The city rose to prominence when Siberia was once again reorganized in 1822, Omsk became the administrative center of the General Governorate of Eastern Siberia rising above the old center of Siberia, Tobolsk. The new governorate was divided into oblasts around the cities of Omsk, Petropavlovsk, Semipalatinsk and Ust-Kamenogrsk populated by Russian colonists and okrugs populated by Kazakh nomads. In subsequent reforms the name of the Oblast was changed repeatedly to The Oblast of The Siberian Kyrgyz (1854), Akmolinsk Oblast (1868), and Omsk Oblast (1917) before finally reverting to the Omsk Governorate in 1918. The authority of the oblast followed further expansion of the empire to Central Asia and included significant parts of modern-day Kazakhstan.
In the 19th century, Omsk, given its strong system of frontier fortresses, became notorious as a premier destination for political exiles and prisoners from the European part of the Russian Empire. Decembrists, Polish rebels, French prisoners of war and political activists of every stripe found their way to Siberia. Among them was Fyodor Dostoyevsky, who spent four years (1850–1854) at the Omsk prison.
The early nineteenth century also saw the growth of industry in the city and in the rest of the Irtysh basin. The Siberian Cossack Army was headquartered in Omsk after 1808 and contributed to the development of the city, by the beginning of the 20th century the Cossacks were a dominant component in the society of both the city of Omsk and the surrounding lands, having reached a population of 174 thousand and holding title to five million hectares of agricultural land. The 18th and 19th centuries also saw the influx of a significant number of German immigrants both from Russia's Volga Regions and from abroad.

### Soviet years

In 1925 the Omsk governorate was dissolved into the newly formed Siberian Krai and again reorganized, this time as an Oblast by order of the All-Russian Central Executive Committee on 7 December 1934. Parts of the Ob-Irtysh Oblast and the West Siberian Krai as well as the southern part of Chelyabinsk Oblast were given over to Omsk. In 1943, Kurgan Oblast created from the western portion of the Chelyabinsk Oblast also got a number of Omsk territories. In 1944, the northern part of the Omsk Oblast along with the districts previously transferred to Kurgan became newly established Tyumen Oblast that included Khanty-Mansi and Yamalo-Nenets autonomous okrugs.
The 1950s saw the creation of the petroleum processing industry, as well as the development of various high-technology facilities that came to define the economy of the Oblast for the remainder of the century.

### Post-Soviet era

With the dissolution of the Soviet Union the oblast became part of the newly independent Russian Federation. The independence of Kazakhstan gave Omsk an international border to the south, while continued federal policy aiming to rectify the effects of Stalin era population transfers led to the creation of a national German district in an area with a significant, although not a majority, German population around the town of Azovo. On 19 May 1996 Omsk Oblast signed a power-sharing agreement with the federal government, granting it autonomy. This agreement would be abolished on 21 December 2001.

## Politics

During the Soviet period, the high authority in the oblast was shared between three persons: The first secretary of the Omsk CPSU Committee (who in reality had the biggest authority), the chairman of the oblast Soviet (legislative power), and the Chairman of the oblast Executive Committee (executive power). Since 1991, CPSU lost all the power, and the head of the Oblast administration, and eventually the governor was appointed/elected alongside elected regional parliament.
The politics in the oblast is governed by the Charter of Omsk Oblast. The laws within the authority of the oblast are passed by the Legislative Assembly of Omsk Oblast which is the legislative (representative) body. The highest executive body is the Omsk Oblast Administration. It also includes the executive bodies of the subdivisions such as districts, and is responsible for the daily administration. The Oblast administration supports the activities of the Governor who is the head of the oblast and acts as guarantor of the observance of the Charter in accordance with the Constitution of Russia.
As of 18 January 2019, the departmental register of registered non-profit organizations of the Office of the Ministry of Justice of the Russian Federation for the Omsk Oblast contains information on 2537 non-profit organizations, including 1332 public associations (national associations - 60, regional branches of political parties - 46, trade unions - 328, children's and youth public associations - 55), 308 religious organizations, 30 Cossack societies, and 20 public associations of Cossacks. For example, in the Omsk Oblast there are regional branches of the political parties United Russia, A Just Russia, the Communist Party of the Russian Federation, and others.
