On November 4th Italy celebrates the “National Unity Day” and the “Armed Forces Day” in remembrance of the end of World War I. On that day in 1918, with the entry of the Italian victorious troops into Trento and Trieste and after almost three years and a half of fighting, the "Great War" ended.
 
The national unification process, which started during the “Risorgimento”, symbolically ended. It  led to the proclamation of the Kingdom of Italy on March 17th 1861.
