My entry into the "Two Things About" discussion: History, History Writing, and History Teaching. Good for introductory lectures. I know "earlier antecedents" is redundant, but it's how I worded it originally, and I still like it: it emphasizes that the immediate causes are not always the important ones, and those causes have causes.... etc. The newer version of this, with Mark Mulligan's pyramid, can be found at: https://www.slideshare.net/jdresner/two-things-about-history You can find the original "Two Things" page at http://www.csun.edu/~dgw61315/thetwothings.html
