Sources?
Ten sources for hundreds of years of history? That means almost none of this can be verified. It also means any editor who wants to can remove what's here. So, consider this if you add to the timeline without a source to point to: your work will most likely be replaced in the future because there's nothing to indicate it's worth anything.
