In what ways did the rulers of Assyria rule over the state and keep the conquered peoples in subjection?

During their heyday, the rulers of Assyria ruled over many nations. This is due to the aggressive foreign policy towards neighboring states. Naturally, many conquered peoples rebelled against the rule of the Assyrian kings. The government reacted rather harshly to this. Whole peoples could be evicted from their country. But the main way to fight the uprisings was the extermination of those who resisted in order to give a clear example to the rest of what awaits anyone who dares to rebel against the rule of the Assyrians.
