When I was in the third grade we spent a whole year on early American history. We learned a little bit about Christianity as part of the lesson.

When I was in the 6th grade we spent almost half the year on the Holocaust. We learned a little bit about Judaism as part of the lesson.

When I was in the 9th grade we spent almost half the year on Greek and Roman gods. We learned a little bit about Greek and Roman religions as part of the lesson.

When I was in 11th grade we spent almost half the year in World History on the middle east. We learned a little bit about Islam as part of the lesson.

When I was in college I took a course in philosophy. Many religions and how the various philosophers felt about their religion and how that created their viewpoint was part of the lesson.

I don't know how you separate religion from history.
