a middle eastern nation, it's been a kingdom for a long time. it was once a british mandate for a few decades, but this never worked well. the sultan has had absolute power in the country for centuries. oman was able to become extremely wealthy with its nationalized oil company. although it's not something that people generally think of in the middle east, this nation has a pretty high standard of living and doesn't have crazy strict relgious laws.
oh man, what's the name of the country? yeah, oman, that's it!
