Describe the role of armies according to machiavelli the prince.?

Niccolò Machiavelli in The Prince describes the role of the three armies: mercenary, auxiliary troops and a prince’s troops.

Mercenary and auxiliary troops are considered to be dangerous because they are driven by ambition, power and money. Therefore, a prince should have his army.  

So, Machiavelli advises the Prince to use internal troops made out of civilians because he could rely on it. They will fight for the kingdom and will not betray him.

“the iliad” (gr: “iliás”) is an epic poem by the ancient greek poet homer, which recounts some of the significant events of the final weeks of the trojan war and the greek siege of the city of troy (which was also known as ilion, ilios or ilium in ancient times).
