Grand Duchy of Moscow in the context of "Golden Horde"

Russia, or the Russian Federation, is a country in Eastern Europe and North Asia. It is the largest country in the world, spanning eleven time zones and sharing land borders with fourteen countries. With a population of over 140 million, Russia is the most populous country in Europe and the ninth-most populous country in the world. It is a highly urbanised country, with sixteen of its urban areas having more than 1 million inhabitants. Moscow, the most populous metropolitan area in Europe, is the capital and largest city of Russia; and Saint Petersburg is its second-largest city and cultural centre.

Human settlement on the territory of modern Russia dates back to the Lower Paleolithic. The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries AD. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Kievan Rus' ultimately disintegrated; the Grand Duchy of Moscow led the unification of Russian lands, leading to the proclamation of the Tsardom of Russia in 1547. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers, developing into the Russian Empire, which remains the third-largest empire in history. However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR—the world's first constitutionally socialist state. Following the Russian Civil War, the Russian SFSR established the Soviet Union with three other Soviet republics, within which it was the largest and principal constituent. The Soviet Union underwent rapid industrialisation in the 1930s, amidst the deaths of millions under Joseph Stalin's rule, and later played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front—rising as a global superpower. With the onset of the Cold War, it competed with the United States for ideological dominance and international influence. The Soviet era of the 20th century saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.

Pskov (Russian: Псков, IPA: [psˈkof] ; see also names in other languages) is a city in northwestern Russia and the administrative center of Pskov Oblast, located about 20 kilometers (12 mi) east of the Estonian border, on the Velikaya River. Population: 193,082 (2021 census); 203,279 (2010 census); 202,780 (2002 census); 203,789 (1989 Soviet census).

Pskov is one of the oldest cities in Russia. During the Middle Ages, it served as the capital of the Pskov Republic and was a trading post of the Hanseatic League before it was incorporated into the Grand Duchy of Moscow and became an important border fortress in the Tsardom of Russia.

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.

The word Rus' or Rus referred initially to a group of Scandinavian Vikings, also known as Varangians, who founded the medieval state of Kievan Rus' in Eastern Europe in the 10th century. The term gradually acquired the meaning of the aforementioned dynastic polity itself, and also the geographic region of its heartlands Kiev, Pereiaslavl' and Chernihiv. Russia is a Hellenized rendering of the same word, and Ruthenia is its Latinized form.

Following the decline of Kievan Rus' in the 12th century, its territory fragmented into multiple polities. The northeastern principality of Vladimir-Suzdal played a crucial role in the eventual rise of the Grand Duchy of Moscow, which, by the 14th to 16th centuries, had consolidated power over most of northeastern Rus'. The name Russia began to appear in official documents during this time, alongside the older term Rus'. By the 15th century, Muscovite rulers adopted the title "Grand Prince of all Rus'," signaling their claim over the legacy of Kievan Rus'. The term Russia gradually replaced Rus', and by the 16th century, under Ivan IV, the state officially became the Tsardom of Russia. Despite this, the term Muscovy persisted in Europe, especially in Latin Catholic regions, but Russia was increasingly recognized across Northern Europe and the courts of the Holy Roman Empire.

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.

The Principality of Yaroslavl (Russian: Ярославское княжество, romanized: Yaroslavskoye knyazhestvo) was a principality with its capital in the city of Yaroslavl. It existed from 1218 until 1463 (de jure until 1471) when it became part of the Grand Duchy of Moscow.
