I want to say that the author wrote for the Latin people (common folk of 1200 in Italy) as his main audience. That is, for the wide audience of general populace and not just for the scholars.
My current sentence (in context) is:
He conceived his work for the Latin populace, that is for the wide audience, which is why it contains a lot of information on how to solve everyday problems, including those connected with business and commerce.
However, I do not like the "for the Latin populace" part. I have tried "for the Latins" and "for the Latin people", but neither sounds right.
Is there a common expression for this in English?
