Vilna- 1921 (failure) and Upper Silesia-1921(s


  • The Polish army took control of Vilna
  • Lithuania appealed to the League for help. When the league protested to Poland, they wouldn't withdraw.
  • Britain wouldn't act alone and because France didn't want to upset Poland(possibly ally to germany in the future)- they wouldn't act either.
  • The League did nothing- FAILURE.

Upper Silesia

  • Upper Silesia was an industrial region in both Germany and Poland. They both wanted control.
  • The people voted and the industrial area voted for Germany and the rural area for POland.
  • The League gave these areas to each country and built safeguards to protect against fighting.
  • Arrangements were made for supplies and this was accepted by both countries.

  • OFFICIALY Mussolini accepted but out of the public eye he changed the league's ruling and Greece payed compensation straight to Italy.
  • Mussolini then withdrew boasting of his triumph!
