This was the first success of the League in the 1920s.
The dispute over the islands was between Finland and Sweden.
Most of the islanders wanted to be ruled by Sweden.
The League investigated and awarded the League to Finland, with safeguards for the islanders, including demilitarisation.
Sweden accepted the judgement.
Upper Silesia, 1921:
It was the second success of the League in the 1920s.
Upper Silesia contained valuableindustrialarea.
It was located on the border between Poland and Germany.
Originally, it was given to Poland by the draftTOV.
However, the Germans protested and a plebiscite was held.
The overall results of the vote suggested that it should be awarded to Germany but in some parts of Silesian territory, there was a majority in favour of Poland.
After riots and protests, the League suggested a partition: WesternUpperSilesia went to Germany and EasternUpperSilesia went to Poland.
Mosul, 1924:
It was the third success of the League in the 1920s.
At first, the Kurdish-populated province of Mosul was claimed by Turkey which was a part of the British-mandated territory of Iraq.
The League investigated the problem and awarded Mosul to Iraq.
Turkey accepted the judgement.
Bulgaria, 1925:
It was the final success of the League in the 1920s.
Greece was ordered to pay 45k pounds in compensation for the invasion of Bulgarianterritory.
This was judged as an inappropriate response to the shooting incident on the shared border in which a Greek sentry was killed in an exchange of fire.
Greece accepted the ruling but it felt that it was treated unfairly and that Italy was treated more generously and differently in similar circumstances.
The League wasn't just concerned with the resolution of disputes. It also wanted to identify issues that affected the peace and wellbeing of the world- directly or indirectly. This led to formation of agencies, commissions and committees.
