Ivan III of Russia in the context of "Rurikids"

The history of Russia begins with the histories of the East Slavs. The traditional start date of specifically Russian history is the establishment of the Rus' state in the north in the year 862, ruled by Varangians. In 882, Prince Oleg of Novgorod seized Kiev, uniting the northern and southern lands of the Eastern Slavs under one authority, moving the governance center to Kiev by the end of the 10th century, and maintaining northern and southern parts with significant autonomy from each other. The state adopted Christianity from the Byzantine Empire in 988, beginning the synthesis of Byzantine, Slavic and Scandinavian cultures that defined Russian culture for the next millennium. Kievan Rus' ultimately disintegrated as a state due to the Mongol invasions in 1237–1240. After the 13th century, Moscow emerged as a significant political and cultural force, driving the unification of Russian territories. By the end of the 15th century, many of the petty principalities around Moscow had been united with the Grand Duchy of Moscow, which took full control of its own sovereignty under Ivan the Great.

Ivan the Terrible transformed the Grand Duchy into the Tsardom of Russia in 1547. However, the death of Ivan's son Feodor I without issue in 1598 created a succession crisis and led Russia into a period of chaos and civil war known as the Time of Troubles, ending with the coronation of Michael Romanov as the first Tsar of the Romanov dynasty in 1613. During the rest of the seventeenth century, Russia completed the exploration and conquest of Siberia, claiming lands as far as the Pacific Ocean by the end of the century. Domestically, Russia faced numerous uprisings of the various ethnic groups under their control, as exemplified by the Cossack leader Stenka Razin, who led a revolt in 1670–1671. In 1721, in the wake of the Great Northern War, Tsar Peter the Great renamed the state as the Russian Empire; he is also noted for establishing St. Petersburg as the new capital of his Empire, and for his introducing Western European culture to Russia. In 1762, Russia came under the control of Catherine the Great, who continued the westernizing policies of Peter the Great, and ushered in the era of the Russian Enlightenment. Catherine's grandson, Alexander I, repulsed an invasion by the French Emperor Napoleon, leading Russia into the status of one of the great powers.

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 Rurik dynasty, also known as the Rurikid or Riurikid dynasty, as well as simply Rurikids or Riurikids, was a noble lineage allegedly founded by the Varangian prince Rurik, who, according to tradition, established himself at Novgorod in the year 862. The Rurikids were the ruling dynasty of Kievan Rus' and its principalities following its disintegration.

The Romanovichi ruled the southwestern territories, which were unified by Roman the Great and his son Daniel, who was in 1253 crowned by Pope Innocent IV as the king of Ruthenia. Galicia–Volhynia was eventually annexed by Poland and Lithuania. The northern and northeastern territories were unified by the Daniilovichi of Moscow; by the 15th century, Ivan III threw off the control of the Golden Horde and assumed the title of sovereign of all Russia. Ivan IV was crowned as the tsar of all Russia, where the Rurik line ruled until 1598, following which they were eventually succeeded by the House of Romanov.

Tsarist autocracy (Russian: царское самодержавие, romanized: tsarskoye samoderzhaviye), also called Tsarism, was an autocracy, a form of absolute monarchy in the Grand Duchy of Moscow and its successor states, the Tsardom of Russia and the Russian Empire. In it, the Tsar possessed in principle authority and wealth, with more power than constitutional monarchs counterbalanced by legislative authority, as well as a more religious authority than Western monarchs. The institution originated during the time of Ivan III (1462−1505) andwas limited with the introduction of constitution and national-level representative assembly (State Duma) after the 1905 Revolution. Still, the term continued to be applied to the monarchy in Russia until the Russian Revolution of 1917 by Russian revolutionaries and afterwards, in the Soviet Union.

The gathering of the Russian lands or Rus' lands (Russian: собирание русских земель) was the process in which new states – usually the Principality of Moscow and the Grand Duchy of Lithuania – acquired former territories of Kievan Rus' from the 14th century onwards, claiming to be its legitimate successor. In Russian historiography, this phenomenon represented the consolidation of a national state centered on Moscow. The sobriquet gatherer of the Russian lands or Rus' Land (Russian: собиратель русской земли, romanized: sobiratel' russkoi zemli) is also given to the grand princes of Moscow by Russian historians, especially to Ivan III. The term is also used to describe the expansion of the Grand Duchy of Lithuania into Rus' principalities; the Lithuanian grand dukes claimed authority over all territories inhabited by Rus' people (East Slavs). Some historians argue that Lithuania began "gathering Rus' lands" before Muscovy did. The rulers of Moscow adopted the title Sovereign of all Russia (later changed to Tsar of all Russia and finally Emperor and Autocrat of all Russia) while the Lithuanian Grand Dukes adopted the title King of the Lithuanians and [many] Ruthenians and later under the Polish–Lithuanian union as King of Poland, Grand Prince of Lithuania, Rus, Prussia, Samogitia, Mazovia and other.

Vasily II Vasilyevich (Russian: Василий II Васильевич; 10 March 1415 – 27 March 1462), nicknamed the Blind or the Dark (Russian: Тёмный), was Grand Prince of Moscow from 1425 until his death in 1462.

He succeeded his father, Vasily I, only to be challenged by his uncle Yuri of Zvenigorod. During this time, Moscow changed hands several times. At one point, Vasily was captured and blinded by his cousin Dmitry Shemyaka in 1446. The final victory went to Vasily, who was supported by most people. Due to his disability, he made his son Ivan III his co-ruler in his later years.
