To study the past is one thing; to apply it is another.
If left in books and archives, History remains a story about them. But when we see the news of yesterday in the headlines of today, history becomes a mirror.
The brutality of the cartels is not new. In the 1500s, Spain burned villages in the Americas, and England razed the fields of Ireland. Cruelty has long been a way to incite fear.
What is different now is not the act itself, but the lens through which we see it: we live in an age that names such violence as evil, where law and conscience say “this is not who we must be.”
To become an applied historian is to live inside that tension. It is to know that the darkness of human nature repeats, and yet to insist that repetition is not destiny. It is to read the patterns, recognize the warnings, and then ask: What role will I play in resisting them?
Applied history does not settle for mere remembering; it builds, teaches, writes, and reforms. It takes the lessons of the past and presses them into the service of the present. And in that way, it makes the future just a little less cruel.
It’s for that reason that I say this:
History is not there to remind us what men once did, but to warn us what men still may do.
