From the editors "What follows is intended to spark the world history teacher's imagination. It is not meant as a prescription or an instant, whole-cloth, replacement for existing content in someone's courses. Instead, what I'm doing is "reasoning with content," by starting with historical information I have access to as a consequence of the trajectory of my teaching and research career thus far. My aim is to model a "bottom up" approach to world history that incorporates the ground underneath our students' feet (wherever they may be) by highlighting a selected world historical process that can be used to link their locality to other places and times in world history. The world historian's goal of illustrating how the local and the global interact can be brought home to where we teach."
