Upsala Idrottsförening, commonly known as Upsala IF, is a Swedish sports club located in the city of Uppsala. Background. Upsala IF was formed on 11 December 1904 when IK Swithiod and Erikslunds IK decided to merge. It was intended that the new club would be named Allmänna Idrottsklubben, Uppsala, but the club was refused entry into the Riksidrottsförbundet (Swedish Sports Confederation) because of the similarity to the name used by AIK in the northern suburbs of Stockholm. The name was eventually changed at the beginning of 1907 to Upsala Idrottsförening and the club joined the RF.
