The Easter Riots (Swedish: Påskkravallerna) is the name given to a period of unrest in Uppsala, Sweden, during the Easter of 1943. The fascist group Swedish Socialist Union (SSS, Swedish: Svensk Socialistisk Samling, previously the National Socialist Workers' Party) held its national congress in Uppsala, amid the Second World War and only days after the Warsaw Ghetto Uprising. The unrest climaxed on 26 April, when the SSS ended the congress by holding a demonstration at the Royal Mounds of Old Uppsala. Thousands of anti-fascists gathered to protest against the Nazi gathering at the Royal Mounds, a historical site that held much political symbolism among Swedish nationalists. Policemen had been called in from Stockholm to defend the demonstration, and after the situation became increasingly tense they resorted to violence, dispersing the peacefully protesting crowds and onlookers alike with heavy force.

Uppsala ( up-SAH-lə; Swedish: [ˈɵ̂pːˌsɑːla] ; archaically spelled Upsala) is the capital of Uppsala County and the fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located 71 km (44 mi) north of the capital Stockholm, it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical centre of Sweden, being the seat of the Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its greatest extent. Today, it serves as the residence of the Governor of Uppsala County. Founded in 1477, Uppsala University is the oldest centre of higher education in Scandinavia. Among the many scholars associated with the city are Anders Celsius, inventor of the centigrade temperature scale that now bears his name, and Carl Linnaeus, the father of taxonomy. Other Uppsala residents include filmmaker Ingmar Bergman, diplomat Dag Hammarskjöld, chemists Jöns Jacob Berzelius and Svante Arrhenius, actress Viveca Lindfors, and singer Malena Ernman.
