Wikipedia:Presentism

Presentism, judging historical events by current standards, should be avoided. Instead, explain – without undue weight – what reliable sources have said regarding changed standards with respect to the topic.

In literary and historical analysis, presentism is the anachronistic introduction of present-day ideas and perspectives into depictions or interpretations of the past. Some modern historians seek to avoid presentism in their work because they believe it creates a distorted understanding of their subject matter.
