Im nationalistic when i celebrate holidays like Thanksgiving or The Fourth of July. Also during special events like the olympics I cheer on american competitor's.
Nationalism began in Italy when citizens got tired of being ruled by various Austrians. The people decided they wanted to become one nation independent from Austria. Italy became a nation state with the help of Camillo di Cavour a Sardinian king who claimed northern italy and Garibaldi the man who liberated southern Italy. The two parts of Italy were finally united as Cavour ruled over them.
