Question about Loyalty

[Boriak]

From the readme:
You can control loyalty to some extent by giving important offices to family members, and by building entertainment and security buildings.

How do you give your family members important offices?

How does the 'rings of loyalty' meter work? Does a family member rebel only if he has one or no rings of loyalty? Or is it a probability equation like with spies/assassins where the eye meter tells you the chance of success?

[DimeBagHo]

Offices are a type of ancillary. They will granted to your family members from time to time as your empire expands, and you can move them from one member to another.

Loyalty is a matter of probability. On hard, three rings is generally safe, while a leader with zero rings is nearly certain to rebel.

Oh yes, the read seals.

The readme says that if I wish to avoid my generals rebelling I should simply destroy the independant faction (Greek or Roman). But the Romans can destroy their rebels very easy compared to the Greeks. Is this difference made on purpose?
