30 sept 1921 año - Upper Silesia. Both Germany and Poland claimed the area so a plebiscite was held to decide
who should have it, and 60% of people voted Germany. However, Poland claimed most of
these votes came from people no longer living in Silesia. They complained and the League
split the area. This was accepted, just. Poland had 50% population, but only 33% land,
and half a million Poles were in confirmed. German land. Germany lost 75% of their mines.
