This sentences seems to be correct : The Babylonians are most famous for their early development of agriculture and trade.
Would it be correct to say (zero article): Babylonians are most famous for their early development of agriculture and trade ?
If not, why not? These sentences are correct for me, would you agree?
Where did Romans come from? (zero article) OR Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. (zero article before Egyptians).
In short, do we always need the determinate article before groups of people who lived in ancient civilizations or are zero articles possible too? What is the difference and how do you know when to use or not use one?
Also how does this compare to nationalities? Italians love cooking is correct when referring to nationality (i.e. all people from Italy) but The Italians love cooking, would be correct only when referring to a group of people one knows, similar to Are the Italians coming over to dinner tonight? Whereas those nationalities which do not have a plural would take the to refer to the whole group, eg. The British speak British English.
Thanks in advance.
