Astrakhan Oblast in the context of "Samara Time"

Kalmykia, officially the Republic of Kalmykia, is a republic of Russia, located in the Volga region of European Russia. The republic is part of the Southern Federal District, and borders Dagestan to the south and Stavropol Krai to the southwest; Volgograd Oblast to the northwest and north and Astrakhan Oblast to the north and east; Rostov Oblast to the west and the Caspian Sea to the east. Through the Caspian Depression, the Kuma river forms Kalmykia's natural border with Dagestan. Kalmykia is the only polity within Europe where the Dharmic religion of Buddhism is the predominant religion; the majority of Kalmyk people are Vajrayana Tibetan Buddhists of the Gelug and Kagyu lineages.

The Kalmykia republic covers an area of 76,100 square kilometres (29,400 square miles), with a small population of about 275,000 residents. The republic of Kalmykia is home of the Kalmyks, a people of Oirat Mongolian origin who are mainly of Tibetan Buddhist faith. The capital of the republic is the city of Elista.

The Nogais (/noʊˈɡaɪ/ noh-GY) are a Turkic people who speak a language from Kipchak branch of Turkic languages and live in Eastern Europe, North Caucasus, Volga region, Central Asia and Turkey. Most are found in Northern Dagestan and Stavropol Krai, as well as in Karachay-Cherkessia, Chechnya and Astrakhan Oblast; some also live in Dobruja (Romania and Bulgaria), Turkey, Kazakhstan, Uzbekistan, Ukraine and a small Nogai diaspora is found in Syria and Jordan. They speak the Nogai language and are descendants of various Mongolic and Turkic tribes who formed the Nogai Horde. There are nine main groups of Nogais: the Ak Nogai, the Karagash, the Koban-Nogai, the Kundraw-Nogai, the Achikulak-Nogai, the Qara-Nogai, the Utars, Bug-Nogai, and the Yurt-Nogai.

Astrakhan (Russian: Астрахань, IPA: [ˈastrəxənʲ] ) is the largest city and administrative centre of Astrakhan Oblast in southern Russia. The city lies on two banks of the Volga, in the upper part of the Volga Delta, on eleven islands of the Caspian Depression, 100 km (62 mi) from the Caspian Sea, with a population of 475,629 residents at the 2021 Census. At an elevation of 28 meters (92 ft) below sea level, it is the lowest city in Russia.

Astrakhan was formerly the capital of the Khanate of Astrakhan (a remnant of the Golden Horde) of the Astrakhan Tatars, and was located on the higher right bank of the Volga, eleven kilometres (6.8 mi) from the present-day city. Situated on caravan and water routes, it developed from a village into a large trading centre, before being conquered by Timur in 1395 and captured by Ivan the Terrible in 1556 and in 1558 it was moved to its present site.

The Volga Delta is the largest river delta in Europe and occurs where Europe's largest river system, the Volga River, drains into the Caspian Sea in Russia's Astrakhan Oblast, north-east of the republic of Kalmykia. The delta is located in the Caspian Depression—the far eastern part of the delta lies in Kazakhstan. The delta drains into the Caspian approximately 60 km (37 mi) downstream from the city of Astrakhan.

The Volga delta has grown significantly in the 20th century because of changes in the level of the Caspian Sea. In 1880, the delta had an area of 3,222 km (1,244 sq mi). Today the Volga Delta covers an area of 27,224 km (10,511 sq mi) and is approximately 160 km (100 mi) across. It has a classical "delta pattern". The delta lies in the arid climate zone, characterized by very little rainfall. The region receives less than one inch of rainfall in January and July in normal years. Strong winds often sweep across the delta and form linear dunes. Along the front of the delta, one will find muddy sand shoals, mudflats, and coquina banks.

The Order of the Red Banner Southern Military District (Russian: Южный военный округ, romanized: Yuzhnyy voyennyy okrug) is a military district of Russia.It is one of the five military districts of the Russian Armed Forces, with its jurisdiction primarily within the North Caucasus region of the country, and Russian bases in South Caucasian post-Soviet states. The Southern Military District was created as part of the 2008 military reforms, and founded by Presidential Decree №1144 signed on September 20, 2010, to replace the North Caucasus Military District, and absorbing the military commands of the Black Sea Fleet and Caspian Flotilla. The district began operation on October 22, 2010, under the command of Colonel-General Aleksandr Galkin.

The Southern Military District is the smallest military district in Russia by geographic size. The district contains 13 federal subjects of Russia: Adygea, Astrakhan Oblast, Chechnya, Dagestan, Ingushetia, Kabardino-Balkaria, Kalmykia, Karachay-Cherkessia, Krasnodar Krai, North Ossetia-Alania, Rostov Oblast, Stavropol Krai and Volgograd Oblast. After the full-scale Russian invasion of Ukraine was launched on 24 February 2022, six oblasts of Ukraine, partially occupied by Russia, were announced as being added to the district: the Crimea, Donetsk, Kherson, Lugansk, Sevastopol and Zaporozhye. These territories are components of Ukraine which since early 2022 have been partially or fully militarily occupied by Russian military forces.

Volgograd Oblast (Russian: Волгоградская область, IPA: [vəɫɡɐˈgratskəjə ˈobɫəsʲtʲ]) is a federal subject (oblast) of Russia, located in the Lower Volga region of Southern Russia. Its administrative center is Volgograd. The population of the oblast was 2,500,781 in the 2021 Census.

Formerly known as Stalingrad Oblast, it was given its present name in 1961, when the city of Stalingrad was renamed Volgograd as part of the process of de-Stalinization. Volgograd Oblast borders Rostov Oblast in the southwest, Voronezh Oblast in the northwest, Saratov Oblast in the north, Astrakhan Oblast and the Republic of Kalmykia in the southeast, and has an international border with Kazakhstan in the east. The two main rivers in European Russia, the Don and the Volga, run through the oblast and are connected by the Volga–Don Canal. Volgograd Oblast's strategic waterways have made it a popular route for shipping and for the generation of hydroelectricity.

A khurul (Kalmyk: хурул, romanized: khurul; Mongolian: хурэ / хүрээ, romanized: khure / khüree or hure or küriye) is a Buddhist monastery (temple, abode) in Kalmyk (Mongol-Oirat) Lamaism. Some of the most famous Kalmyk khuruls are the Burkhan Bakshin Altan Sume (contemporary) in Elista, Republic of Kalmykia, Russia, and the Khosheutovsky khurul (which was originally in the Kalmyk AO / Kalmyk ASSR, but is now located in Astrakhan Oblast, Russia).

The Khanate of Astrakhan was a Tatar rump state of the Golden Horde. The khanate existed in the 15th and 16th centuries in the area adjacent to the mouth of the Volga river, around the modern city of Astrakhan. Its khans claimed patrilineal descent from Toqa Temür, the thirteenth son of Jochi and grandson of Genghis Khan.

Mahmud bin Küchük established the Khanate in the 1460s. The capital was the city of Xacitarxan, also known as Astrakhan in Russian chronicles. Its territory included the Lower Volga valley and the Volga Delta, including most of what is now Astrakhan Oblast and the steppeland on the right bank of Volga in present-day Kalmykia. To the south was the Caspian Sea, to the east the Nogai Horde, and to the west Nogais who were theoretically subjects of the Crimean Khanate.
