It was to remove the ignominious portrayal of the Native American as savage and wild that historians adopted 1992 as the year to depict them in their true light as members of civilizations worthy of study and respect.
Q1: What does in their true light mean here?
Q2: I cannot justify the role of as the year in the sentence.
Q3: I can guess, in their true light means what they are actually and indeed. In this regard, can we construct sentences like:
- This documentary shows the ancient people in their true light
or, depict something in its true light is a idiom in which depict must be included.
