Prewar conflicts in europe concerned all of the following except:
control of the balkan states
alsace-lorraine
north african colonies
italians under austrian rule
italy joining the central powers

Prewar conflicts in Europe concerned all of the following except Italy joining Central Powers. This was due to the fact that Italy wasn’t one of this mentioned Central Powers.

I hope it helps, Regards.      

The prewar conflicts in Europe didn't concern themselves that much about Italians. This is because there wasn't much animosity going on between Italians and Austrians, compared to the other problems which arose at the time.
