View all animal worksheets. The Irtysh River was the site of ancient civilizations of the Mongol and Turkic peoples.

One of the many famous battles fought along this river is the Battle of Irtysh River, which was fought in between the Tang dynasty and the Western Turkic Khaganate. With the battle resulting in the defeat of the latter, it was one of the key events leading to the supremacy of the Tang over the Turks in the region for some time to come. Over the years, different dynasties have fought numerous wars with each other to establish their power in the Irtysh River basin.

Currently, however, the river is shared by the 3 countries of China, Kazakhstan and Russia. In modern times, the waters of the Irtysh River support the needs of millions living along its banks in China, Kazakhstan, and Russia.

In Kazakhstan and Russia, the river serves as a significant transport route for maritime war machines, passenger ships and cargo ships during the ice-free season. A large number of hydroelectric power stations have been built along the Irtysh in China, Kazakhstan, and Siberia to meet the electricity needs of the human settlements based near the river. The Irtysh is longer, but the Ob has more volume, and when they meet, at Khanty Mansiysk a town named for the two dominant local indigenous groups , their course becomes sluggish and marshy.

The far north of Russia is mostly flat and marshy, with little precipitation. Agriculture is severely limited by harsh climate and year-round permafrost. The Ob becomes divided into many ribbons, subject to enormous spring floods and dangerous ice flows during summer thaws. Here the river valley can at times reach 25 mi 40 km wide. Fortified wooden stockades were built at river junctions as trappers and merchants moved eastward, including such cities as Tobolsk on the Irtysh, and Salekhard on the Ob.
