This chapter talks about expelling barbarians from Italy. Just as it was in the fifth century, when the barbarians took over the Roman empire, Italy still had barbarians in their soil. Nicholas, is sending a message to all princes in their different principalities to raise in arms and fight against them.
Now, we have seen all over this book that the author is clearly stating to wage war and to endure a strong hand whenever is necessary to keep a government up. In this final chapter he talks about joining forces for the barbarians to leave Italian provinces.
This is to me a classical example of medieval time’s way of doing things, like; they would join forces to fight a common enemy. In today’s nowadays or modern times, what I can get from them is World War II, where different nations joined to fight against other nations, who they believed had it wrong.
In Central America, I would quote the example of William Walker, the pirate, wanting to take over the region. All of Central Americans joined and expelled him in one of the most glorious fights of our history.
To sum all up, this is a brilliant book for politicians, if they wish to stay in power, the methods, even though medieval at times, are the same in it essence.
