Fall of the Western Roman Empire.

As it was hard to established certain political authority, rulers of these kingdoms introduced feudal system, that was based on loyalty. It was the dominant form throughout Middle Ages.

As well, because Italy was not unified, it was not as powerful as countries like Spain, France and England.
