I often see people wear the label of historian without the vaguest clue what it means. Not knowing that a true historian is interested in all of human history.
True historians are as much interested in the Pre-Colombian tribal wars of modern day Peru as they are in the Battle of Hasting. They aren’t selective or bias. They do not let their personal feelings, religious belief, nor opinions get in the way of what they record and whats to learn about the past.
They search for, read about anything dealing with humans and cultures of the past they can find and is always looking for that which no one is talking about.
Even those who specialized in a certain eras or cultures are as zestful about the other eras as those who have no specialty.
Anthropology and history or herstory goes together like love and marriage. You can’t have a love or zest for one without the other.
A true test if you’re dealing with a true historian is you will note their involvement in diversity of the human cultures.
