The government of Darius (Dan 6:1-6:1)

“It pleased Darius

To set over the kingdom

One hundred twenty satraps,

Stationed throughout

The whole kingdom.”

This Darius appears to be based on Darius I (522-486 BCE), the third Persian Emperor. This new ruler in Persian Babylon set up 120 satraps throughout the old Babylonian kingdom. These satraps were provincial governors in the Persian, not Babylonian empire.
