I cannot properly tell you how much I love history. I think I was one of the few children who would sit and watch a history documentary with my dad and enjoy it. And although I have my favorite areas of history I love learning about (Medieval times, ancient Rome and Egypt and random highwaymen/outlaws/thieves to name a few) all of history is pretty cool to me.
I just. History is awesome. It's like a giant book of our past; all of us characters with our own back story. (maybe that's just the writer in me, I don't know) The human race writing itself. Most of the time without a thought that we are doing it.
History also helps the future. If we learn from the mistakes and successes from the past, then our future would be brighter. We can avoid the pot holes and blunders of times past, and maybe make up for it.
As a writer, I find inspiration in history. For example, my current work in progress is about two brothers who go off to find the Book of Merlin. A great sea going adventure. Even though no such book exists, the story is influenced by Arthurian legend. I had to research pirates and 1700's sailing techniques and other such bits to make sure my story was at least reasonably accurate.
I cannot tell you how often I lost track of time just reading up on random history. Pirates, after looting a ship, returned a stone fireplace they stole because it belonged to Jack Daniels. Poland avoided the Black Plague because it was cleaner than other countries around it due to it's populace being mainly Jewish. George Washington's teeth were not made of wood, but instead from cow teeth.
I understand that not everyone shares this love as history as I do. (Yay for me that my whole family enjoys history.) In fact, some may even find history-gasp-boring. To each their own. I, for one, cannot stand math. But I need to have a working understanding of it to function. Also, it's useful in writing, believe it or not. Same goes for history. It's important to know something of history when writing; you never know when it might come in handy.Characters and worlds in your writing have history as well. Without them, well, your people and the lands they live in is just blank. And blank is boring. Build the history, because that gives purpose. It explains things. I'm not saying tell your readers the complete history of the country of Arei and the rulers. But sprinkle that history throughout the story to flesh it out.
