Poland was not alone in its newfound opportunities and troubles. Most if not all of the newly independent neighbours began fighting over borders: Romania fought with Hungary over Transylvania, Yugoslavia with Italy over Rijeka, Poland with Czechoslovakia over Cieszyn Silesia, with Germany over Poznań and with Ukrainians over Eastern Galicia (Galician War). Ukrainians, Belarusians, Lithuanians, Estonians and Latvians fought against themselves and against the Russians, who were just as divided.
