Around 18,000 BC, during the Weichselian glaciation, a thick cover of ice stretched over Scandinavia,[2] which eventually receded from the islands around 9000 BC.[3] Around 8000 BC the highest peaks of the then submerged archipelago rose from the Baltic Sea.[4] The sea levels would alternate in the Baltic Sea,[5] but a land bridge to Åland never formed, indicating the first humans came by boat or over the ice.[1]
Due to the forebulge effect after the icecaps melted, the area around Åland is still rising several millimeters per year, marginally expanding the archipelago's surface.[6]
Many Bronze Age villages have been found on Åland. Ceramics and animal bones have been found on Kökar.[9] Signs of livestock have been found from the Bronze Age on Åland.[10]
Viking age
Dense settlements were built on Fasta Åland during this time.[8] Large burial grounds have been found on Åland as well.[11] Arabic mint coins from 400 C.E. have been found on Åland.[1] On Åland, there are six hillforts from this period.[12] There was extensive trade with other areas, as far as Arabia.[8][13][14] The first signs of Christianity were found from the Middle Ages.[8]
Middle Ages
The first wooden churches are built on Åland.[8][13] Åland Islands might have been occupied by Eric the Saint, other sources claim Åland was already an integral part of Sweden. The first stone churches where built in the 1300s to 1400s on Åland.[13][8] When construction began on Kastelholm Castle is not exactly known but it most likely began in the 1380s[8][15] Kastelholm is first mentioned in 1388[15] Many noble families would live on Åland.[13] The Franciscan order would found a monastery on Hamnö in Kökar in the 1400s.[13] Åland would join the Kalmar Union.
Swedish rule
In 1507 the Danish naval officer Søren Norby would capture Kastelholm castle.[13][8] Many battles would take place between the Danish and Swedish over Kastelholm between 1521 - 1523.[8]Gustav Vasa would make Åland a royal castle county in 1537.[13] Gustav Vasa would also establish 3 large breeding farm estates.[13] Catholicism came to an end on Åland and monasteries would be closed and the churces and monasteries had give their silver to the state.[13]
Between 1665 and 1668 the Kastelholm witch trials would take place on Åland where over 20 women would be accused of witchcraft and would be executed.[13] The first school would be founded on Åland in the 1600s in Saltvik.[13]
During the Great Northern War many Ålanders fled west from the advancing Russians.[13] The Battle of Grengam would take place in Åland during the Great Northern war on 7 August 1720.
In 1829 the Fortress of Bomarsund begins construction.[8][17] As part of the Crimean War the Anglo-French invasion of Åland takes place. The coalition force attacks and destroys the fortress of Bomarsund during the Battle of Bomarsund.[8] The British prime minister Palmerston had protested against this fortification some twenty years prior, without effect. The Treaty of Paris forbids the fortification of the islands after the destruction of Bomarsund.[18]
As the result of abundant Anopheles claviger mosquitoes, malaria was endemic in Åland for at least 150 years, with severe outbreaks being recorded in the 18th century, and in 1853 and 1862.[19]
In 1882, Lemströms canal opens to ship traffic.[8] A telegraph cable is in use from Mariehamn to Nystad in 1877. The Önningeby artists' colony would be founded in 1886. The first telephone is installed in Mariehamnin 1892.[20] A Russian garrison is established in the Islands in 1906. Some attention went to the earlier Treaty of Paris when Russia, under pretext of stopping the smuggling of arms into Finland, placed considerable naval and military forces on the islands. Secret Treaty of Björkö (Russia and Germany), which gives Russia a free hand to install military forces on the islands is signed in 1907.
World War 1
World War I breaks out and Russia begins building fortifications on Åland.[8][21] Fortifications would be built on Saggö, Börkö, Sålis, Frebbenby, Mellantrop, Kungsö, Korsö, Herrö, Storklobb och Kökar.[21] Many Ålanders wanted to join Sweden.[8][22] A referendum would be held on Åland and 95% was willing to join Sweden.[23] Finland would declare independence from Russia in 1917 and had sent troops to take over Åland. Sweden would send troops to Åland on 13 February 1918. The Finnish Whites would take Boxö and Saggö. Finnish reds would land on Åland on 17 February 1918. The Finnish Whites and Reds would fight over Godby and the Whites would win. Germans would land on Åland on 28 February 1918.
Interwar period
In 1918 the islanders would internationally plead to reunite with Sweden. In 1919 Sweden brings the question before the Paris Peace Conference on 18 March but the islands remain part of Finland.[18] Also in 1919 the 1919 Ålandic status referendum takes place where the islanders would have a unofficial referendum to integrate into Sweden. In 1921 the Åland convention re-establishes the demilitarised status of the islands.
