* An example of a decree by a human ruler was the proclamation by Caesar Augustus that everyone living in the Roman Empire must go back to their hometown in order to be counted in a census.
* To decree something, or to "issue a decree," means to give an order that must be obeyed. This could be translated as to "order" or to "command" or to "formally require" or to "publicly make a law."
* Something that is "decreed" to happen means that this "will definitely happen" or "has been decided upon and will not be changed" or "declared absolutely that this will happen."
