How can we successfully achieve the pre-contextualization point? (How far back in history do we have to go to?)
IF (really really big IF) the DBQ is about 1200, go back to about 1000. The land-based empires: Islam / the Islamic Empires & the Mongols.
You don’t need to go back at all. You can write contextualization about a broader topic before or during the time period of the prompt - as long as you connect it to the topic of the prompt!
