Sometimes. It all depends on context. Do you have one in mind?

Hi. Do we put the definitive article "the" before "Jewish people or English people?"
Here is one: "The greatest representatives of Jewish people have always shared Armenians’ pain and tragedy."
I am not sure about the word representatives there- you're talking about a people spread across many nations, so it is hard for them to have representatives.
