Etymology

The city is named after the river Oulujoki, which originates in the lake Oulujärvi. There have been a number of other theories for the origin of the name Oulu. One possible source is a word in the Sami language meaning 'flood water', but there are other suggestions. At minimum, the structure of the word requires that, if originally given by speakers of a Uralic language, the name must be a derivative. In all likelihood, it also predates Finnish settlement and is thus a loanword from one of the now-extinct Saami languages once spoken in the area.
The most probable theory is that the name derives from the Finnish dialectal word oulu, meaning "floodwater", which is related to e.g. Southern Sami åulo, meaning "melted snow", åulot meaning "thaw". Two other word families have also been speculated to be related. The first is seen in the Northern Savo dialectal word uula and its Sami counterpart oalli, both meaning "river channel". The second is the Uralic root reconstructed as *uwa, meaning "river bed". To either of these roots, some Sami variety would have to be assumed having added further derivational suffixes.

History

Oulu is situated by the Gulf of Bothnia, at the mouth of river Oulujoki, which was an official trading centre.
Following the Treaty of Nöteborg in 1323, the status of Oulu was disputed in its ownership, as both the Novgorod Republic and the Kingdom of Sweden held much influence. In 1345, the Swedish annexed territory up to the Kemi River for the Diocese of Turku. In 1375, the Novgorodians built a defensive castle which was later captured by the Swedish forces in 1377.
The 1400s were characterized by Russian raids in the region, during these raids captured people would be killed and/or taken back to the region of Russia. In 1531, the city was granted permission to act as a trading post. In 1590, the Oulu Castle was built by the Swedes and in 1595, the Treaty of Teusina firmly established Sweden's control over Oulu.
The city was founded on 8 April 1605 by King Charles IX of Sweden, and granted city privileges in 1610. In 1765, Oulu received township rights granting them to trade outside of Sweden. Oulu was the capital of the Province of Oulu from 1776 to 2009.
In 1822, a major fire destroyed much of the city, especially the city centre as most of the city was made from wood. The architect Carl Ludvig Engel, chiefly known for the neoclassical buildings around Helsinki Senate Square, was enlisted to provide the plan for its rebuilding. With minor changes, this plan remains the basis for the layout of Oulu's town center. The Oulu Cathedral was built in 1832 to his designs, with the spire being finished in 1844. During the Åland War, part of the Crimean War, Oulu's harbour was raided by the British fleet, who destroyed ships and burned tar houses, leading to international criticism.
The city was the site of the Battle of Oulu on 3 February 1918 between the Whites and the Reds during the Finnish Civil War.
