Farming/ slavery.
This answer really depends on what the question is asking, the southern economy banked heavily off of farming, BUT it was impossible to provide and have such an abundance of crops without slavery. So, it depends on the options you have.
Hope this helps, man!
English, Chinese, French, Japanese, are a few that come to mind, If you are talking about Imperialistic Great Britian and France during the Age of Imperialism. I'm not sure about all of those other ones, except Latin was I'm sure dead around that age.
The feature is the rule of law. Unlike people, legislature cannot be affected by passion and if law rules then everyone is equal in the eyes of law. If a man rules and has absolute power, they can be affected by various things that might make them abuse their power, and law cannot abuse power on its own.
