Italians are descendants of Rome and are well equipped. Why are their fighting capacities so low?

Although Italians are descendants of Rome, they did not directly inherit the blood of Rome. He inherited a long history of culture. In fact, when the farming people slowly developed a set of culture with a long history, its militancy was gradually eliminated. So in fact, Italians can't compete with those barbaric peoples in the north.

The northern Germanic people are quite brave and good at using destructive means, similar to the Huns in ancient China. But at that time, the Roman Empire lasted for such a long time, and all aspects were weak in the later period, and the army could not continue to maintain its original combat effectiveness. On the contrary, it is a nation-state gradually formed by all ethnic groups in the north, with certain fighting capacity and national style. They opened the road to conquest and went south directly, destroying the ancient Roman Empire.

The Italians who stayed at that time, as a group of intellectuals, stayed in a small place. Moreover, the Italians are the seat of the ancient papal state, and Christianity was quite aggressive before it spread to the whole world in the early stage. But in the later period, it gradually became docile, mainly because the Pope was no longer in charge of the regime, while the Italian regime was controlled by some nobles with a long history. These nobles, because of their long-term luxury and little understanding of war, have gradually become less aggressive.
