The league of nations had some successes and some failures. Their successes were in the Aaland Islands and in Upper Silecia.
In the Aaland islands the problem was that Sweden and Finland both claimed ownership of these islands, and it seemed that war could broke between them. The League’s action was to give Finland the islands and, for lucky, Sweden was in accord.
In Upper Silesia, the problem was that this area of land in the polish and Germany borders had a mixed population. The league interfered doing a plebiscite. After the voting, the territory was divided between the both countries.
For lucky this problems were solved, but the league failed in other important problems: in Corfu and in Vilna.
In Corfu the problem was that an Italian general was killed in the borders of Albania and Greece. Mussolini demanded reparations and an enquiry. The Greeks refused and Mussolini bombard and invaded Corfu. The league’s action was to made a comite and the decision was to ask Italy to pay 50 m. lire. Mussolini claimed that the league had no right to interfere and said that if this interference continued, Italy would leave the league. the authority of the league had been undermined. In this problem the league showed its debility by going back when a big country gave them pressure.
In Vilna the problem was between Poland and Lithuania. Vilna was the capital of Lithuania, but the population was predominantly Polish. Polish invaded Vilna and Lithuania went to talk with the league. The league’s action was : “nothing”. It was unbelievable that they didn’t care and do nothing, it was a league made up to gave peace to the countries, ¿would this reactions made the people to be peaceful in the 1920’s? No, definitely no.
In my conclusion, as I said from the start, the Locarno treaty was the one who gave peace to European people in the 1920’s. The Locarno treaty only had successes and made people to feel comfortable and secure , the league of nations, beside it had some successes, its failures were terrible and people would remember them for ever.
