Can anybody give me more examples on how to use these words? I know for sure than you should not use dominion as domain for the Internet but apart from that sight difference both words seem to be synonyms to me.

```
and Death shall have no Dominion by Dylan Thomas

```

**UPDATE** 

to [Wordreference](http://www.wordreference.com/thesaurus/dominion) as a governed area they have the same meaning? So I guess "The domain of the Roman Empire" or "The dominion of the Roman Empire" are both legal. Am I right?
