some hundreds/ some hundred

[sb70012]

1. Some hundreds years ago, our city belonged to Azerbaijan.
2. Some hundred years ago, our city belonged to Azerbaijan.

Hi friends,

Would you please tell me which one is grammatically ok?
I am confused about the usage of "hundreds".

If our city belonged to Azerbaijan approximately 100 years ago [for example, 98 or 103 years], then it is "Some hundred years ago". However, it would be more normal to express it as "Around one hundred years ago", or "Approximately one hundred years ago".

If our city belonged to Azerbaijan several hundreds of years ago [ for example, 400 or 700 years], then it is "Some hundreds of years ago". Again, it would be more normal to express it as "Several hundreds of years ago", or "Several hundred years ago", or just "Hundreds of years ago". Note the "of" following the plural "hundreds", but not the singular "hundred".
