Khanate of Kazan in the context of "Volga Tatars"

Ivan IV Vasilyevich (Russian: Иван IV Васильевич; 25 August [O.S. 15 August] 1530 – 28 March [O.S. 18 March] 1584), commonly known as Ivan the Terrible, was Grand Prince of Moscow and all Russia from 1533 to 1547, and the first Tsar and Grand Prince of all Russia from 1547 until his death in 1584. Ivan's reign was characterised by Russia's transformation from a medieval state to a fledgling empire, but at an immense cost to its people and long-term economy.

Ivan IV was the eldest son of Vasili III by his second wife Elena Glinskaya, and a grandson of Ivan III. He succeeded his father after his death, when he was three years old. A group of reformers united around the young Ivan, crowning him as tsar in 1547 at the age of 16. In the early years of his reign, Ivan ruled with the group of reformers known as the Chosen Council and established the Zemsky Sobor, a new assembly convened by the tsar. He also revised the legal code and introduced reforms, including elements of local self-government, as well as establishing the first Russian standing army, the streltsy. Ivan conquered the khanates of Kazan and Astrakhan, bringing the entire length of the Volga river under Russian control.

The Turco-Mongol or Turko-Mongol tradition was an ethnocultural synthesis that arose in Asia during the 14th century among the ruling elites of the Golden Horde and the Chagatai Khanate. The ruling Mongol elites of these khanates eventually assimilated into the Turkic populations that they conquered and ruled over, thus becoming known as Turco-Mongols. These elites gradually adopted Islam, as well as Turkic languages, while retaining Mongol political and legal institutions.

The Turco-Mongols founded many Islamic successor states after the collapse of the Mongol khanates, such as the Kazakh Khanate, the Tatar khanates that succeeded the Golden Horde (e.g., Crimean Khanate, Astrakhan Khanate, Khanate of Kazan), and the Timurid Empire, which succeeded the Chagatai Khanate in Central Asia. Babur (1483–1530), a Turco-Mongol prince and a descendant of Timur, founded the Mughal Empire, which ruled much of the Indian subcontinent. The Turks and Tatars also ruled part of Egypt, exercising political and military authority during the Mamluk Sultanate.

Kazan is the largest city and capital of Tatarstan, Russia. The city lies at the confluence of the Volga and the Kazanka rivers, covering an area of 425.3 square kilometres (164.2 square miles), with a population of over 1.3 million residents, and up to nearly 2 million residents in the greater metropolitan area. Kazan is the fifth-largest city in Russia, being the most populous city on the Volga and within the Volga Federal District.

Historically, Kazan was the capital of the Khanate of Kazan, and was conquered by Ivan the Terrible in the 16th century, at which point the city became a part of the Tsardom of Russia. The city was seized (and largely destroyed) during Pugachev's Rebellion (1773–1775), but was later rebuilt during the reign of Catherine the Great. In the following centuries, Kazan grew to become a major industrial, cultural and religious centre of Russia. In 1920, after the Russian SFSR became a part of the Soviet Union, Kazan became the capital of the Tatar Autonomous Soviet Socialist Republic (Tatar ASSR). Following the dissolution of the Soviet Union, Kazan remained the capital of the Republic of Tatarstan.

The siege of Kazan or Fall of Kazan in 1552 was the final battle of the Russo-Kazan Wars and led to the fall of the Khanate of Kazan. Conflict continued after the fall of Kazan, however, as rebel governments formed in Çalım and Mişätamaq, and a new khan was invited from the Nogais. This guerrilla war lingered until 1556.

The Russo-Kazan Wars were a series of short, intermittent wars fought between the Grand Principality of Moscow and the Khanate of Kazan between 1437 and 1556. Most of these were wars of succession in Kazan, in which Muscovy intervened on behalf of the dynastic interests of its main ally, the Crimean Khanate. For most of the period, neither side sought to conquer the other, until Ivan the Terrible decided to annex Kazan upon the successful 1552 siege, which was followed by a rebellion lasting until 1556.

Vasili III Ivanovich (Russian: Василий III Иванович; Christian name: Gavriil; monastic name: Varlaam; 25 March 1479 – 3 December 1533) was Grand Prince of Moscow and all Russia from 1505 until his death in 1533.

He was the second son of Ivan III by his second wife Sophia Paleologue. Following on the ambitions of his father, Vasili annexed Pskov and Ryazan – the last remaining autonomous Russian territories – and captured the city of Smolensk from Lithuania. He also strengthened Russian influence in Kazan and the Volga region. Several nobles were exiled, sentenced, or executed for criticizing his policies.

Yermak Timofeyevich (Russian: Ермак Тимофеевич, IPA: [jɪrˈmak tʲɪmɐˈfʲejɪvʲɪt͡ɕ]; 1532 (supposedly) – August 5 or 6, 1585) was a Cossack ataman who started the Russian conquest of Siberia during the reign of the Russian Tsar Ivan the Terrible. He is today a hero in Russian folklore and myths.

Russian interests in the fur trade fueled their desire to expand east into Siberia. The Tatar Khanate of Kazan established by Ulugh Muhammad was the best entryway into Siberia. In 1552, Ivan the Terrible's modernized army toppled the khanate. After the takeover of Kazan, the tsar looked to the powerful and affluent Stroganov merchant family to spearhead the eastward expansion. In the late 1570s, the Stroganovs recruited Cossack fighters to invade Asia on behalf of the tsar. These Cossacks elected Yermak as the leader of their armed forces, and in 1582 Yermak set out with an army of 840 to attack the Khanate of Sibir.
