How did Persian empire keep its people from rebelling against it?

The Persian Empire maintained control over its diverse populations through a combination of tolerance, effective governance, and infrastructure development. By allowing local customs, religions, and laws to continue, the Persians fostered loyalty among conquered peoples. The establishment of a sophisticated administrative system, including satraps (governors) who oversaw various regions, helped ensure efficient governance. Additionally, the construction of roads and communication networks facilitated trade and mobility, further integrating the empire and reducing the likelihood of rebellion.
