Nationalism & The Creation Of Italy

I think that nationalism are countries who have broken up from a larger country and have mad their own country / Nation. I am a Nationalistic because I live in a country which is not ruled by another empire or another country. The country I live in has its own law, currency, flag, we have symbols for this country. In this country we all speak a common language, we have a history for this country. Most of the people in this country follow a certain culture. I do many thing that show i am Nationalistic I follow the culture of the country I live in. I speak the common language of this country. I use the currency of this country, I do the Pledge of Allegiance to the flag of this country.
Nationalism was also used to create the nation of Italy. Before a long time ago Italy used to be a part of the Austria-Hungary empire. But when other countries started to declare independence Italy was very influenced by them. So, when Italy wanted their independence the had a war of independence. They're were riots all over Italy which also triggered many other riots in Europe. They named their nation and slowly broke away from the Austria-Hungary empire. Then they made a flag for their nation was not part of any other nation or empire. So this is how Italy used nationalism to gain independence.
