The Tsar of all Russia, formally the Sovereign, Tsar and Grand Prince of all Russia, was the title of the Russian monarch from 1547 to 1721. During this period, the state was a tsardom.
The first Russian monarch to be crowned as tsar was Ivan IV, who had held the title of sovereign and grand prince. In 1721, Peter I adopted the title of emperor and proclaimed the Russian Empire. The old title continued to be popularly used to refer to the emperor.
The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about 22,800,000 km (8,800,000 sq mi), roughly one-sixth of the world's landmass, making it the third-largest empire in history, behind only the British and Mongol empires. It also colonized Alaska between 1799 and 1867. The empire's 1897 census, the only one it conducted, found a population of 125.6 million with considerable ethnic, linguistic, religious, and socioeconomic diversity.
From the 10th to 17th century, the Russians had been ruled by a noble class known as the boyars, above whom was the tsar, the absolute monarch. The groundwork of the Russian Empire was laid by Ivan III who ruled from 1462 to 1505, and greatly expanded his domain, established a centralized Russian national state, and secured independence against the Tatars. His grandson, Ivan IV (r. 1533–1584), became in 1547 the first Russian monarch to be crowned tsar of all Russia. Between 1550 and 1700, the Russian state grew by an average of 35,000 km (14,000 sq mi) per year. Peter I transformed the tsardom into an empire, and fought numerous wars that turned a vast realm into a major European power. He moved the Russian capital from Moscow to the new model city of Saint Petersburg, and led a cultural revolution that introduced a modern, scientific, rationalist, and Western-oriented system. Catherine the Great (r. 1762–1796) presided over further expansion of the Russian state by conquest, colonization, and diplomacy, while continuing Peter's policy of modernization. Alexander I (r. 1801–1825) helped defeat the militaristic ambitions of Napoleon and subsequently constituted the Holy Alliance, which aimed to restrain the rise of secularism and liberalism across Europe. Russia further expanded to the west, south, and east, strengthening its position as a European power. Its victories in the Russo-Turkish Wars were later checked by defeat in the Crimean War (1853–1856), leading to a period of reform and conquests in Central Asia. Alexander II (r. 1855–1881) initiated numerous reforms, most notably the 1861 emancipation of all 23 million serfs.
The emperor and autocrat of all Russia was the official title of the Russian monarch from 1721 to 1917.
The title originated in connection with Russia's victory in the Great Northern War (1700–1721) and appeared as an adaptation of the tsar's title under the accepted system of titling in Europe. The title was transformed from the previous title of tsar and grand prince of all Russia. The old title tsar (or tsaritsa) continued to be popularly used to refer to the emperor (or empress) until the monarchy was abolished in 1917.
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.
Alexei Mikhailovich (Russian: Алексей Михайлович, IPA: [ɐlʲɪkˈsʲej mʲɪˈxajləvʲɪtɕ]; 19 March [O.S. 9 March] 1629 – 8 February [O.S. 29 January] 1676), also known as Alexis, was Tsar of all Russia from 1645 until his death in 1676. He was the second Russian tsar from the House of Romanov.
He was the first tsar to sign laws on his own authority and his council passed the Sobornoye Ulozheniye of 1649, which strengthened the bonds between autocracy and the lower nobility. In religious matters, he sided closely with Patriarch Nikon during the schism in the Russian Orthodox Church which saw unpopular liturgical reforms.
The House of Romanov (also transliterated as Romanoff. Russian: Романовы, romanized: Romanovy, IPA: [rɐˈmanəvɨ]) was the reigning imperial house of Russia from 1613 to 1917. They achieved prominence after Anastasia Romanovna married Ivan the Terrible, the first crowned tsar of all Russia. Nicholas II, the last Emperor of Russia, and his immediate family were executed in 1918, but there are still living descendants of other members of the imperial house.
The house consisted of boyars in Russia (the highest rank in the Russian nobility at the time) under the reigning Rurik dynasty, which became extinct upon the death of Feodor I in 1598. The Time of Troubles, caused by the resulting succession crisis, saw several pretenders and imposters lay claim to the Russian throne during the Polish-Lithuanian occupation. On 21 February 1613, the Zemsky Sobor elected Michael Romanov as tsar, establishing the Romanovs as Russia's second reigning dynasty.
