History of Finland
Prehistory
If the archeological finds from Wolf Cave are the result of Neanderthals' activities, the first people inhabited Finland approximately 120,000–130,000 years ago. The area that is now Finland was settled in, at the latest, around 8,500 BC during the Stone Age towards the end of the last glacial period. The artefacts the first settlers left behind present characteristics that are shared with those found in Estonia, Russia, and Norway. The earliest people were hunter-gatherers, using stone tools.

The first pottery appeared in 5200 BC, when the Comb Ceramic culture was introduced. The arrival of the Corded Ware culture in Southern coastal Finland between 3000 and 2500 BC may have coincided with the start of agriculture. Even with the introduction of agriculture, hunting and fishing continued to be important parts of the subsistence economy.

In the Bronze Age permanent all-year-round cultivation and animal husbandry spread, but the cold climate phase slowed the change. Cultures in Finland shared common features in pottery and also axes had similarities but local features existed. The Seima-Turbino phenomenon brought the first bronze artefacts to the region and possibly also the Finno-Ugric languages. Commercial contacts that had so far mostly been to Estonia started to extend to Scandinavia. Domestic manufacture of bronze artefacts started 1300 BC with Maaninka-type bronze axes . Bronze was imported from Volga region and from Southern Scandinavia.
In the Iron Age population grew especially in Häme and Savo regions. Finland proper was the most densely populated area. Cultural contacts to the Baltics and Scandinavia became more frequent. Commercial contacts in the Baltic Sea region grew and extended during the eighth and ninth centuries.
Main exports from Finland were furs, slaves, castoreum, and falcons to European courts. Imports included silk and other fabrics, jewelry, Ulfberht swords, and, in lesser extent, glass. Production of iron started approximately in 500 BC.
At the end of the ninth century, indigenous artefact culture, especially women's jewelry and weapons, had more common local features than ever before. This has been interpreted to be expressing common Finnish identity which was born from an image of common origin.
An early form of Finnic languages spread to the Baltic Sea region approximately 1900 BC with the Seima-Turbino-phenomenon. Common Finnic language was spoken around Gulf of Finland 2000 years ago. The dialects from which the modern-day Finnish language was developed came into existence during the Iron Age. Although distantly related, the Sami retained the hunter-gatherer lifestyle longer than the Finns. The Sami cultural identity and the Sami language have survived in Lapland, the northernmost province, but the Sami have been displaced or assimilated elsewhere.
The 12th and 13th centuries were a violent time in the northern Baltic Sea. The Livonian Crusade was ongoing and the Finnish tribes such as the Tavastians and Karelians were in frequent conflicts with Novgorod and with each other. Also, during the 12th and 13th centuries several crusades from the Catholic realms of the Baltic Sea area were made against the Finnish tribes. According to historical sources, Danes waged at least three crusades to Finland, in 1187 or slightly earlier, in 1191 and in 1202, and Swedes, possibly the so-called second crusade to Finland, in 1249 against Tavastians and the third crusade to Finland in 1293 against the Karelians. The so-called first crusade to Finland, possibly in 1155, is most likely an unreal event. Also, it is possible that Germans made violent conversion of Finnish pagans in the 13th century. According to a papal letter from 1241, the king of Norway was also fighting against "nearby pagans" at that time.

Swedish era

As a result of the crusades (mostly with the second crusade led by Birger Jarl) and the colonization of some Finnish coastal areas with Christian Swedish population during the Middle Ages, including the old capital Turku, Finland gradually became part of the kingdom of Sweden and the sphere of influence of the Catholic Church. Due to the Swedish conquest, the Finnish upper class lost its position and lands to the new Swedish and German nobility and to the Catholic Church. In Sweden even in the 17th and 18th centuries, it was clear that Finland was a conquered country and its inhabitants could be treated arbitrarily. Swedish kings visited Finland rarely and in Swedish contemporary texts Finns were portrayed to be primitive and their language inferior.
Swedish became the dominant language of the nobility, administration, and education; Finnish was chiefly a language for the peasantry, clergy, and local courts in predominantly Finnish-speaking areas. During the Protestant Reformation, the Finns gradually converted to Lutheranism.
In the 16th century, Mikael Agricola published the first written works in Finnish, and Finland's current capital city, Helsinki, was founded by Gustav I of Sweden. The first university in Finland, the Royal Academy of Turku, was established in 1640. The Finns reaped a reputation in the Thirty Years' War (1618–1648) as a well-trained cavalrymen called "Hakkapeliitta", that division excelled in sudden and savage attacks, raiding and reconnaissance, which King Gustavus Adolphus took advantage of in his significant battles, like in the Battle of Breitenfeld (1631) and the Battle of Rain (1632). Finland suffered a severe famine in 1696–1697, during which about one third of the Finnish population died, and a devastating plague a few years later.
In the 18th century, wars between Sweden and Russia twice led to the occupation of Finland by Russian forces, times known to the Finns as the Greater Wrath (1714–1721) and the Lesser Wrath (1742–1743). It is estimated that almost an entire generation of young men was lost during the Great Wrath, due mainly to the destruction of homes and farms, and to the burning of Helsinki. By this time Finland was the predominant term for the whole area from the Gulf of Bothnia to the Russian border.
Two Russo-Swedish wars in twenty-five years served as reminders to the Finnish people of the precarious position between Sweden and Russia. An increasingly vocal elite in Finland soon determined that Finnish ties with Sweden were becoming too costly, and following the Russo-Swedish War (1788–1790), the Finnish elite's desire to break with Sweden only heightened.

Even before the war there were conspiring politicians, among them Georg Magnus Sprengtporten, who had supported Gustav III's coup in 1772. Sprengtporten fell out with the king and resigned his commission in 1777. In the following decade he tried to secure Russian support for an autonomous Finland, and later became an adviser to Catherine II.[62] In the spirit of the notion of Adolf Ivar Arwidsson (1791–1858) – "we are not Swedes, we do not want to become Russians, let us therefore be Finns" – a Finnish national identity started to become established.[63]
Notwithstanding the efforts of Finland's elite and nobility to break ties with Sweden, there was no genuine independence movement in Finland until the early 20th century. As a matter of fact, at this time the Finnish peasantry was outraged by the actions of their elite and almost exclusively supported Gustav's actions against the conspirators. (The High Court of Turku condemned Sprengtporten as a traitor around 1793.) The Swedish era ended in the Finnish War in 1809.
Russian era
On 29 March 1809, having been taken over by the armies of Alexander I of Russia in the Finnish War, Finland became an autonomous Grand Duchy in the Russian Empire with the recognition given at the Diet held in Porvoo. This situation lasted until the end of 1917. In 1812, Alexander I incorporated the Russian Vyborg province into the Grand Duchy of Finland. In 1854, Finland became involved in Russia's involvement in the Crimean War, when the British and French navies bombed the Finnish coast and Åland during the so-called Åland War. During the Russian era, the Finnish language began to gain recognition. From the 1860s onwards, a strong Finnish nationalist movement known as the Fennoman movement grew, and one of its most prominent leading figures of the movement was the philosopher J. V. Snellman, who was strictly inclined to Hegel's idealism, and who pushed for the stabilization of the status of the Finnish language and its own currency, the Finnish markka, in the Grand Duchy of Finland. Milestones included the publication of what would become Finland's national epic – the Kalevala – in 1835, and the Finnish language's achieving equal legal status with Swedish in 1892.

The Finnish famine of 1866–1868 killed approximately 15% of the population, making it one of the worst famines in European history. The famine led the Russian Empire to ease financial regulations, and investment rose in following decades. Economic and political development was rapid. The gross domestic product (GDP) per capita was still half of that of the United States and a third of that of Britain.
In 1906, universal suffrage was adopted in the Grand Duchy of Finland. However, the relationship between the Grand Duchy and the Russian Empire soured when the Russian government made moves to restrict Finnish autonomy. For example, the universal suffrage was, in practice, virtually meaningless, since the tsar did not have to approve any of the laws adopted by the Finnish parliament. Desire for independence gained ground, first among radical liberals and socialists. The case is known as the "Russification of Finland", driven by a declaration called the February Manifesto by the last tsar of Russian Empire, Nicholas II, on 15 February 1899.
