Crash Course is produced and directed by Stan Muller, our script supervisor is Danica Johnson, the show is written by my high school history teacher Raoul Meyer and myself, and our graphics team is Thought Bubble. Oh, our intern, I'm sorry, Meredith the Intern. Our intern is Meredith Danko. Last week's Phrase of the Week was homogenous, mythologized, unitary polity. Thank you for that suggestion. If you want to guess this week's Phrase of the Week or suggest future ones you can do so in comments, where you can also ask questions about today's video that will be answered by our team of historians. Thanks for watching Crash Course, remember you can get this shirt, the Mongol shirt, or our poster at DFTBA.com.
