Volga region in the context of "Nogais"

The Bulgars (also Bulghars, Bulgari, Bolgars, Bolghars, Bolgari, Proto-Bulgarians) were Turkic semi-nomadic warrior tribes that flourished in the Pontic–Caspian steppe and the Volga region between the 5th and 7th centuries. They became known as nomadic equestrians in the Volga-Ural region, but some researchers trace Bulgar ethnic roots to Central Asia.

During their westward migration across the Eurasian Steppe, the Bulgar tribes absorbed other tribal groups and cultural influences in a process of ethnogenesis, including Iranic, Uralic, and Hunnic tribes. The Bulgars spoke a Turkic language, the Bulgar language of the Oghuric branch. They preserved the military titles, organization, and customs of Eurasian steppes as well as pagan shamanism and belief in the sky deity Tangra.

The Onoghurs, Onoğurs, or Oğurs (Ὀνόγουροι, Οὔρωγοι, Οὔγωροι; Onογurs, Ογurs; "ten tribes", "tribes") were a group of Turkic nomadic equestrians who flourished in the Pontic–Caspian steppe and the Volga region between the 5th and 7th centuries, and spoke an Oghuric language.

The Russian famine of 1921–1922, also known as the Povolzhye famine (Russian: Голод в Поволжье 'Volga region famine'), was a severe famine in the Russian Soviet Federative Socialist Republic that began early in the spring of 1921 and lasted until 1922. The famine resulted from the combined effects of severe drought, the continued effects of World War I, economic disturbance from the Russian Revolution, the Russian Civil War, and failures in the government policy of war communism (especially prodrazvyorstka). It was exacerbated by rail systems that could not distribute food efficiently.

The famine killed an estimated five million people and primarily affected the Volga and Ural River regions. Many of the starving resorted to cannibalism. The outbreaks of diseases such as cholera and typhus were also contributing factors to famine casualties.

Chagatai (چغتای, Čaġatāy), also known as Turki, Eastern Turkic, or Chagatai Turkic (Čaġatāy türkīsi), is a Turkic language that was once widely spoken across Central Asia. It remained the shared literary language in the region until the early 20th century. It was used across a wide geographic area including western or Russian Turkestan (i.e. parts of modern-day Uzbekistan, Turkmenistan, Kazakhstan, Kyrgyzstan), Eastern Turkestan (where a dialect, known as Kaşğar tılı, developed), Crimea, the Volga region (such as Tatarstan and Bashkortostan), etc. Chagatai is the direct ancestor of the Uzbek and Uyghur languages. Kazakh and Turkmen, which are not within the Karluk branch but are in the Kipchak and Oghuz branches of the Turkic languages respectively, were nonetheless heavily influenced by Chagatai for centuries.

Ali-Shir Nava'i was the greatest representative of Chagatai literature.

Islam is the second-largest religion in Europe after Christianity. Although the majority of Muslim communities in Western Europe formed as a result of immigration, there are centuries-old indigenous European Muslim communities in the Balkans, Caucasus, Crimea, and Volga region. The term "Muslim Europe" is used to refer to the Muslim-majority countries in the Balkans and the Caucasus (Albania, Azerbaijan, Bosnia and Herzegovina, Kosovo, and Turkey) and parts of countries in Central and Eastern Europe with sizable Muslim minorities (Bulgaria, Montenegro, North Macedonia, and some republics of Russia) that constitute large populations of indigenous European Muslims, although the majority are secular.

Islam expanded into the Caucasus through the Muslim conquest of Persia in the 7th century and entered Southern Europe after the Umayyad conquest of Hispania in the 8th–10th centuries; Muslim political entities existed firmly in what is today Spain, Portugal, Sicily, and Malta during the Middle Ages. The Muslim populations in these territories were either converted to Christianity or expelled by the end of the 15th century by the indigenous Christian rulers (see Reconquista). The Ottoman Empire expanded into Southeastern Europe and consolidated its political power by invading and conquering huge portions of the Serbian and Bulgarian empires, and the remaining territories of the region, including the Albanian and Romanian principalities, and the kingdoms of Bosnia, Croatia, and Hungary between the 14th and 16th centuries. Over the centuries, the Ottoman Empire gradually lost its European territories. Islam was particularly influential in the territories of Albania, Bosnia and Herzegovina, and Kosovo, and has remained the dominant religion in these countries.

The Soviet famine of 1930–1933 was a famine in the major grain-producing areas of the Soviet Union, including Ukraine and different parts of Russia (Kazakhstan, North Caucasus, Kuban, Volga region, the southern Urals, and western Siberia). Major factors included the forced collectivization of agriculture as a part of the First Five-Year Plan and forced grain procurement from farmers. These factors in conjunction with a massive investment in heavy industry decreased the agricultural workforce. It is estimated that 5.7 to 8.7 million people died from starvation across the Soviet Union. In addition, 50 to 70 million Soviet citizens starved during the famine but ultimately survived.

During this period Soviet leader Joseph Stalin ordered the kulaks (land-owning proprietors) "to be liquidated as a class". As collectivization expanded, the persecution of the kulaks, ongoing since the Russian Civil War, culminated in a massive campaign of state persecution in 1929–1932, including arrests, deportations, and executions of kulaks. Some kulaks responded with acts of sabotage such as killing their livestock and destroying crops designated for consumption by factory workers. Despite the vast death toll in the early stages, Stalin chose to continue the Five Year Plan and collectivization. By 1934, the Soviet Union had established a base of heavy industry, at the cost of millions of lives.
