War Changes Italy's Eastern Border

June 10, 1940

What Happened

When Italy entered World War II, it dramatically affected the country's eastern regions near Yugoslavia. The areas of Istria, Fiume (now called Rijeka), and Dalmatia became contested territories as war broke out, forcing many residents to make difficult choices about where their loyalties lay.

Impact on Citizenship

When Italy entered World War II, it affected citizenship rights in its eastern territories. If your ancestor lived in Istria, Fiume (now Rijeka), or Dalmatia, they needed to leave these regions by this date to maintain their Italian citizenship. Those who remained in these areas after this date typically lost their Italian citizenship, which affects their descendants' ability to claim citizenship today.
