Enslave
What is it ?
Enslaving an empire basically forces that empire to submit to you. When this
happens the slave empire pays you tribute, at 15% of their income. This tribute
will then be transferred over to your tribute reserves; in return you transfer
the credits to your empire's treasury to use.
This allows empires to expand differently rather than just getting more
planets. However nothing comes with out a price. When you enslave another
empire you will have to send in reinforcements whenever another empire tries to
enslave that empire. Note that when another empire enslaves your slave empire,
you will lose tribute coming from particular slave empire. Reinforcement
usually comes from your 4rd and 5th stack only. If you do not have any 4rd or
5th stack, then no reinforcements will be sent.
How to do it ?
To enslave an empire, simply change your attack type to `Enslave` in the
attacking page. You will have to do a significant amount of damage prior to
enslaving the empire.
If I am not enslaved ?
To encourage empires to be independent (or to fight for independence), all
empires not enslaved will generate an additional 15% more income. This bonus
does not apply when income is negative.
