options for the last blank: for instance, as a result

Explanation:

The sentence before the blank describes Amanirenas' actions (protecting Kush's land and pushing out the Roman Empire), and the sentence after describes Kush experiencing peace. "As a result" shows a cause - effect relationship, which is appropriate here. "For instance" is used for giving examples, which doesn't fit the context.

Answer:

As a result
