Alexander I of Russia in the context of "Imperial Russia"

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 Russo-Persian War of 1804–1813 was one of the many wars between the Persian Empire and Imperial Russia, and, like many of their other conflicts, began as a territorial dispute. The new Persian king, Fath Ali Shah Qajar, wanted to consolidate the northernmost reaches of his kingdom—modern-day Georgia—which had been annexed by Tsar Paul I several years after the Russo-Persian War of 1796. Like his Persian counterpart, the Tsar Alexander I was also new to the throne and equally determined to control the disputed territories.

The war ended in 1813 with the Treaty of Gulistan which ceded the previously disputed territory of Georgia to Imperial Russia, and also the undisputed Iranian territories of Dagestan, most of what is modern Azerbaijan, and minor parts of Armenia.

Turku (/ˈtʊərkuː/ TOOR-koo; Finnish: [ˈturku] ; Swedish: Åbo, Finland Swedish: [ˈoːbu] ) is a city in Finland and the regional capital of Southwest Finland. It is located on the southwestern coast of the country at the mouth of the River Aura. The population of Turku is approximately 207,000, while the metropolitan area has a population of approximately 317,000. It is the 6th–most populous municipality in Finland, and the third–most populous urban area in the country after Helsinki and Tampere.

Turku is Finland's oldest city. It is not known when Turku was granted city status. Pope Gregory IX first mentioned the town of Aboa in his Bulla in 1229, and this year is now used as the founding year of the city. Turku was the most important city in the eastern part (today's Finland) of the Kingdom of Sweden. After the Finnish War, Finland became an autonomous Grand Duchy of the Russian Empire in 1809, and Turku became the capital of the Grand Duchy. However, Turku lost its status as capital only three years later in 1812, when Tsar Alexander I of Russia decided to move the capital to Helsinki. It was only after the last great fire in 1827 that most government institutions were moved to Helsinki along with the Royal Academy of Turku, founded in 1640, which later became the University of Helsinki, thus consolidating Helsinki's position as the new capital. Turku was Finland's most populous city until the late 1840s and remains the regional capital, an important business and cultural centre, and a port.

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 Holy Alliance (German: Heilige Allianz; Russian: Священный союз, romanized: Svyashchennyy soyuz), also called the Grand Alliance, was a coalition linking the absolute monarchist great powers of Austria, Prussia, and Russia, which was created after the final defeat of Napoleon at the behest of Emperor Alexander I of Russia and signed in Paris on 26 September 1815.

The alliance aimed to restrain secular liberalism in Europe in the wake of the devastating French Revolutionary Wars and the Napoleonic Wars; it nominally succeeded in this until the Crimean War. Chancellor Otto von Bismarck managed to reunite the Holy Alliance, as League of the Three Emperors, following the unification of Germany in 1871. However the alliance faltered by the 1880s due to Austrian and Russian conflicts of interest over the decline of the Ottoman Empire.

Nicholas I (6 July [O.S. 25 June] 1796 – 2 March [O.S. 18 February] 1855) was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland from 1825 to 1855. He was the third son of Paul I and younger brother of his predecessor, Alexander I. Nicholas's thirty-year reign began with the failed Decembrist revolt. He is mainly remembered as a reactionary whose controversial reign was marked by geographical expansion, centralisation of administrative policies, and repression of dissent both in Russia and among its neighbors. Nicholas had a happy marriage that produced a large family, with all of their seven children surviving childhood.

Nicholas's biographer Nicholas V. Riasanovsky said that he displayed determination, singleness of purpose, and an iron will, along with a powerful sense of duty and a dedication to very hard work. He saw himself as a soldier—a junior officer consumed by spit and polish. A handsome man, he was highly nervous and aggressive. Trained as a military engineer, he was a stickler for minute detail. In his public persona, stated Riasanovsky, "Nicholas I came to represent autocracy personified: infinitely majestic, determined and powerful, hard as stone, and relentless as fate."

The Senate of Finland (Finnish: Suomen senaatti; Swedish: Senaten för Finland) combined the functions of cabinet and supreme court in the Grand Duchy of Finland from 1816 to 1917 and in independent Finland from 1917 to 1918.

The body that would become the Senate was established on August 18, 1809, when Tsar Alexander I of Russia summoned the Diet of Porvoo and directed the Diet to draw up regulations for a Government Council. In 1816, Alexander renamed this body the Senate to demonstrate that it was equal to rather than inferior to its Russian equivalent.

Finland declared its independence on 6 December 1917. The formal Declaration of Independence was only part of the long process leading to the independence of Finland.
