Hubris was a basic concept of the worldview of the ancient Greeks, which largely followed Hellenism into modern times.
If someone behaved violently, recklessly, arrogantly, and insultingly toward the physical and moral rules, the laws of the state, and especially the gods, in an overestimation of his abilities and power (physical, but especially political, military, and economic), he was considered to have committed "Hubris." This could be translated as "insult" and could be described as behaving as if trying to transcend mortal nature and become God, thereby insulting and angering them.
Using the form Hubris → Atis(Ate) → Nemesis → Tisis, we can say that the ancient Greeks believed that Hubris usually caused the intervention of the gods and especially Zeus, who sent Atis to the abuser, which was the blurring and blindness of the mind.
This in turn led the abuser to new offenses until he committed a very grave error which brought about the "Nemesis", the wrath and vengeance of the gods, which brought the "Tisis", that is, his punishment and destruction.

This whole philosophy, wrapped with the religious mantle to gain respect, greater power and timelessness, is hidden in the law and structure of human nature and aims at the balance and harmony of human life.
We see in the works of the tragic poets many references to the punishment or purification that generations of people who fell into "sins" were subjected to or cities that needed to be purified because of the disrespect of leaders.
Hubris could be called recklessness or excessive enthusiasm or, for example, the disobedience of Icarus or Phaethon.
As Hubris we may consider all three campaigns of the Persians against the Greeks, and especially the last one of 480 B.C., which was prepared by Xerxes with pomp and arrogance, and left the battlefields defeated in spite of the excessive size of his army and fleet.
