Title: Grand Duchy of Finland
Content:  The Grand Duchy of Finland (Suomen suuriruhtinaskunta; Storfurstendömet Finland; Великое княжество Финляндское, Velikoye knyazhestvo Finlyandskoye, alternatively Grand Principality of Finland) was the predecessor state of modern Finland. It existed between 1809 and 1917 as an autonomous part of the Russian Empire. Originating in the 16th century as a titular grand duchy held by the King of Sweden, the country became autonomous after its annexation by Russia in the Finnish War of 1808–1809. The Grand Duke of Finland was the Romanov Emperor of Russia, represented by the Governor-General. Due to the governmental structure of the Russian Empire and Finnish initiative, the Grand Duchy's autonomy expanded until the end of the 19th century. The Senate of Finland, founded in 1809, became the most important governmental organ and the precursor to the modern Government 
Title: Architecture of Finland
Content:  The cornerstone of Finland as a state was laid in 1809 at the Diet of Porvoo, where Czar Alexander I proclaimed himself constitutional ruler of the new Grand Duchy of Finland and promised to maintain the faith and laws of the land. The creation of a capital was a clear indication of the Czar's will to make the new Grand Duchy a functioning entity. On April 8, 1812 Alexander I declared Helsinki the capital of the Grand Duchy of Finland. At that time Helsinki was only a small wooden town of about 4000 inhabitants, albeit with huge island fortress of Sveaborg 
Title: Grand Duke of Finland
Content:  Grand Duke of Finland, alternatively the Grand Prince of Finland (Suomen suuriruhtinas, Storfurste av Finland, Великий князь Финляндский), was, from around 1580 to 1809, a title in use by most Swedish monarchs. Between 1809 and 1917, it was the official title of the ruler of the autonomous Grand Principality of Finland, who was also the Emperor of Russia. The anachronistic female form of the title in English would be Grand Duchess of Finland (Storfurstinna av Finland, Suomen suuriruhtinatar). The only women to have used the title were the Swedish queens regnant Kristina and Ulrika Eleonora. A few crown princes of Sweden also were called Grand Duke of Finland.
Title: Grand Duke of Finland
Content:  During the Finnish War between Sweden and Russia, the four estates of occupied Finland were assembled at the Diet of Porvoo on 29 March 1809 to pledge allegiance to Emperor Alexander I of Russia, who had already earlier during the war adopted the title Grand Duke of Finland to his long list of titles. Following the Swedish defeat in the war and the signing of the Treaty of Fredrikshamn on 17 September 1809, Finland became in some aspects an autonomous Grand Duchy, as in an informal real union with the Russian Empire. The Imperial Grand Duke of Finland ruled Finland through his Governor General and a national Senate appointed by him. Although no Grand Duke ever explicitly recognised Finland as a separate state in its own right, the country nevertheless enjoyed a high degree of autonomy, until its independence in 1917.

The government offices that remained in Turku were finally moved to the new capital after the Great Fire of Turku, which destroyed a large portion of the city in 1827. After the fire, a new and safer city plan was drawn up by German architect Carl Ludvig Engel, who had also designed the new capital, Helsinki. Turku remained the largest city in Finland for another twenty years.  In 1918, a new university, the Åbo Akademi – the only Swedish-language university in Finland – was

Content:  Finland, the Supreme Court of Finland, and the Supreme Administrative Court of Finland. Economic, social and political changes in the Grand Duchy of Finland closely paralleled those in the rest of the Russian Empire and in the rest of Europe. The economy grew slowly during the first half of the 19th century. The reign of Alexander II (1855–1881) saw significant cultural, social and intellectual progress, and an industrializing economy. Tensions increased after Saint Petersburg adopted Russification policies in 1889; the new circumstances saw the introduction of limited autonomy and the reduction of Finnish cultural expression. Unrest in Russia and Finland during the First World War (1914–1918) and the subsequent collapse of the Russian Empire in 1917 resulted in the Finnish Declaration of Independence and the end of the Grand Duchy.
Title: Monarchy of Finland
Content:  Following the capture of Finland from Sweden by Russia in 1809, Finland kept the Swedish constitution formally intact and became an autonomous region within the Russian Empire under the title of Grand Principality of Finland. The Russian Emperor wielded the powers formerly reserved for the King of Sweden as the Grand Prince of Finland, creatively applying the autocratic Swedish constitution of 1772 and 1789. The first Grand Prince, Alexander I of Russia, was the grandson of Duke Peter of Holstein-Gottorp, who had held the imperial throne for just 6 months in 1762 as Peter III of Russia.

Title: Finland–Russia relations
Content:  Finland–Russia relations have been conducted over many centuries, from wars between Sweden and Russia in the early 18th century, to the planned and realized creation and annexation of the Grand Duchy of Finland within the Russian Empire during Napoleonic times in the early 19th century, to the dissolution of the personal union between Russia and Finland after the abdication of Russia's last czar in 1917, and subsequent birth of modern Finland, with support of the bolshevik (Soviet) Russian government. Finland had its own civil war with minor involvement by Soviet Russia, was later invaded by the USSR, and had its internal politics influenced by it. Relations since then have been both warm and cool, fluctuating with time. Russia has an embassy in Helsinki, a consulate-general in Turku and consulates in Lappeenranta and Mariehamn. Finland has an embassy in Moscow, a consulate-general in Saint Petersburg and two branches of the consulate (in Murmansk and Petrozavodsk).
