On March 1, 2008, a new region appeared on the map of Russia - the Trans-Baikal Territory. It became part of the Siberian Federal District and borders on the Irkutsk and Amur regions, the republics of Yakutia and Buryatia, China and Mongolia.
The administrative center is the city of Chita.
The development of Transbaikalia began in the middle of the 7th century. Not far from the confluence of the rivers Ingoda and Chita, a Cossack detachment founded the first fortifications. Soon a whole system of prisons arose here, the Cossacks entrenched themselves not only in the valleys of the Selenga, Ingoda, Shilka, but also on the right bank of the Amur and Argun. The Argun prison became the extreme southeastern outpost of the new Cossack settlements. Thus, Transbaikalia turned out to be the territory of Russian politics, which was extremely disliked by neighboring China, which had its own views on the lands of Dauria - that was how Transbaikalia and the Amur region were generally called at that time.
