In 1946, the Italian people voted to form the Italian Republic with 54% of the population voting in favor of the Republic, while 46% voting in favor of the monarchy.
Most of the support for the Republic were in Italy's North, while support for the Monarchy was in Italy's South.
A thing which was observed by many people, is that the monarchy would have won in 1946 had Vittoro Emmanuel III abdicated in favor of his son in 1943, rather than 1946. The Italian public grew angered at Vittoro Emmanuel, and while Umbrio II was popular, he was only in power for a month before the monarchy was voted out.
What would have happened in Vittoro Emmanuel III abdicated in 1943/1944 in favor of his son, Umbrio II, who would have likely won the election to keep the monarchy.
How would the Kingdom if Italy survive to modern day.
