how were different people were treated in Arad empire?

It appears there might be a confusion regarding the term "Arad empire," as there is no widely recognized historical empire by this name. However, if you are asking about how different people were treated in ancient empires in general or in a similarly named empire, I can certainly provide some information on that topic.

In many ancient empires, such as the Persian Empire, the Roman Empire, or the various dynasties of China, there was a wide diversity of people under their control, and treatment could vary greatly depending on several factors, including:

1. **Social Status**: People of high social status, such as nobility, aristocracy, and wealthy merchants, usually enjoyed privileges and influence that commoners did not. They often had better living conditions, access to education, and the ear of the government.

2. **Ethnicity and Race**: Different ethnic groups within an empire were often treated according to their relationship with the imperial power—whether they were seen as allies, conquered peoples, or somewhere in between. In some cases, there was tolerance and even assimilation of diverse cultures; in others, there was discrimination and harsh treatment.

3. **Legal Status**: Citizenship vs. non-citizenship could make a massive difference in how one was treated within an empire. For example, Roman citizens were protected by Roman laws and entitled to certain rights that were not extended to non-citizens or slaves.

4. **Occupation**: People's jobs or roles within the society also influenced their treatment. Tradespeople, soldiers, artists, bureaucrats, and religious officials each had their own roles and could expect treatment commensurate with their position and contribution to the empire.

5. **Gender**: Gender roles were typically well-defined, and treatment varied significantly based on gender. In many societies, men had more legal rights and social freedoms, while women were often limited to domestic spheres and had lesser agency in public life.

6. **Religion**: Freedom of religion varied across empires. Some, like the Achaemenid Persians, were known for their relative tolerance of other religions. Others imposed state religions or were less tolerant, leading to persecution or even forced conversions.

6. **Geographical Location**: The core regions of an empire, where the capital and main administrative bodies were located, often received more attention and better treatment than outlying provinces or newly conquered territories.

If you meant a specific empire or civilization that closely resembles "Arad," please provide additional details or correct the name, and I'd be happy to provide more targeted information.
