Document 4: Örebro SK: The 2003 season under new coach Stefan Lundin started well for Örebro, but yet again a poor ending of the season saw the team end up in eighth place. Promising goalkeeper John Alvbåge and Danish veteran Lars Larsen introduced themselves and soon became favourites of the Örebro crowd. The 2004 season became one of the darkest years in club history. First, Örebro had to fight hard to avoid relegation. A heroic effort with five straight wins at the end of the season earned a mid table finishing (seventh, later amended to eighth), but in the end effort proved futile. Economic problems had haunted ÖSK for a period of time as the club faced major deficits. Even after yet another heroic attempt by both supporters and sponsors the club was relegated by "Elitlicensnämnden" (eng: The Elite license board), who ruled that the balance sheet of the club did not comply with the standards of the Swedish Football Association. Örebro SK's appeal failed and the club was forced to play in Superettan.

Document 15: League of Nations: Åland is a collection of around 6,500 islands in the Baltic Sea, midway between Sweden and Finland. The islands are almost exclusively Swedish-speaking, but in 1809, the Åland Islands, along with Finland, were taken by Imperial Russia. In December 1917, during the turmoil of the Russian October Revolution, Finland declared its independence, but most of the Ålanders wished to rejoin Sweden. The Finnish government considered the islands to be a part of their new nation, as the Russians had included Åland in the Grand Duchy of Finland, formed in 1809. By 1920, the dispute had escalated to the point that there was danger of war. The British government referred the problem to the League's Council, but Finland would not let the League intervene, as they considered it an internal matter. The League created a small panel to decide if it should investigate the matter and, with an affirmative response, a neutral commission was created. In June 1921, the League announced its decision: the islands were to remain a part of Finland, but with guaranteed protection of the islanders, including demilitarisation. With Sweden's reluctant agreement, this became the first European international agreement concluded directly through the League.
